They are both correct.

Step-by-step explanation:

As we can see, it does not matter whether you plug in x or y in a system of equatins. One thing somebody might be skeptical about in this equation is that one of the equations does not contain a variable. BUT, if reading closer, one can see that both x and y have to be in one of the equations to make the other true.

Hope this helped!

We will see that both Jared and Nicole are correct.

So we know that Jared found an equation:

y = x + 10, then he substituted y for (x + 10) on the other equation, this would be the substitution method, and Jared is correct so far.

We also know that Nicole found the equation:

x = y - 10

And she replaced x by y - 10 on the other equation, she is also correct.

Each one just substituted a different variable, that is why they have different approaches, but in both cases the substitutions are correct.

The height that describes how tall the tree is is 37.5 feet.

To determine how tall the tree is, we need to apply the proportion formula to arrive at the right answer. We express the values this way:

\(\frac{x}{75} = \frac{50}{30}\)

Now we cross multiply to have

30x = 1125

x = 1125/30

= 37.5

So, the length of the tree is 37.5 feet.

In geometry, the two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.

In geometry, the two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.

Formally speaking, two sets of points are said to be congruent if—and only if—they can be changed into the one another by an isometry, which is a combination of rigid motions like translation, rotation, and reflection. This indicates that either object may be precisely aligned with the other object by moving and reflecting it, but not by resizing it. So if we can cut out and then perfectly match up two separate plane figures on a piece of paper, they are congruent. The paper may be turned over.

Triangles with two pairs of congruent sides and an included congruent angle are said to be congruent by ASA.

According to the graph, sides TU, FG, and BC are congruent, as well as sides TV, HG, and AB. Additionally, it shows that angles G and B are congruent as well as angles U, F, and C. Triangle TUV is eliminated because ASA cannot find another triangle that is equivalent to angle U of triangle TUV using the information provided.

The ordered pair (3, 3) satisfies both equations simultaneously, and hence it is the solution to the system of equations represented by the Graph.

The system of equations represented by the graph is 2x - 3y = 9 and -x + 4y = 12.

The graph contains two lines that intersect at a point, which is the solution to the system of equations.What is a System of Equations?A system of equations is a set of two or more equations that are to be solved simultaneously. These equations have the same variables.

If the system has two equations, it is called a system of two linear equations in two variables. The variables represent two unknown quantities, and the equations represent the relationships between them.Graphical Representation of a System of EquationsThe graphical representation of a system of equations is done by plotting the lines that are represented by the equations on the same coordinate plane.

If the two lines intersect at a point, then that point is the solution to the system of equations.The solution to the system of equations is the ordered pair that satisfies both equations simultaneously. This means that if we substitute the values of the ordered pair into both equations, the equations will be true.

The Solution to the System of Equations represented by the GraphThe graph of the system of equations given in the question contains two lines that intersect at a point. The point of intersection is (3, 3).

Therefore, the solution to the system of equations is (3, 3).Now we can verify that the ordered pair (3, 3) is the solution to both equations. When we substitute x = 3 and y = 3 in the first equation, we get:2x - 3y = 9 ⇒ 2(3) - 3(3) = 9 ⇒ 6 - 9 = -3This equation is true. Now we can substitute x = 3 and y = 3 in the second equation, we get:-x + 4y = 12 ⇒ -(3) + 4(3) = 12 ⇒ -3 + 12 = 9

This equation is also true.

Therefore, the ordered pair (3, 3) satisfies both equations simultaneously, and hence it is the solution to the system of equations represented by the graph.

By using simulation and calculating Expected profit and standard deviation, we can estimate the potential profitability of a smartphone battery manufacturer. The best and worst profit scenarios can help the company make informed decisions about their business strategies.

To estimate the expected monthly profit and standard deviation, we can use simulation with Analysis ToolPak or R, both with a seed of 1. Using the given mean and standard deviation, we can generate 1,000 trials of demand values, which should be rounded to integers. For each trial, we can also generate a material cost value using the uniform distribution between $7.00 and $8.50, rounded to two decimal places. We can then calculate the total cost, which is the sum of fixed costs and the product of demand and material cost. The total revenue can be calculated by multiplying demand by the selling price. The profit is the difference between total revenue and total cost.
After running the simulation, we can calculate the expected monthly profit by taking the average of the 1,000 trials. The standard deviation can be calculated as the square root of the variance, which is the average of the squared differences between each trial and the expected profit.
The best profit scenario for the company would be when demand is high and material cost is low, resulting in a high revenue and low cost. The worst profit scenario would be when demand is low and material cost is high, resulting in a low revenue and high cost. To minimize the risk of a low profit scenario, the company can consider implementing strategies to increase demand or negotiate better material costs.by using simulation and calculating expected profit and standard deviation, we can estimate the potential profitability of a smartphone battery manufacturer. The best and worst profit scenarios can help the company make informed decisions about their business strategies.

The best profit scenario is $1,800 and the worst profit scenario is -$1,950.

a. Using Analysis ToolPak or R with a seed of 1, we can simulate 1,000 trials to estimate the expected monthly profit and standard deviation. The formula for calculating profit is:

profit = (selling price * demand) - (material cost * demand) - fixed costs

Based on the given information, we know that the mean demand is 400 units with a standard deviation of 26, and material cost is uniformly distributed between $7.00 and $8.50. Using these values and simulating 1,000 trials, we can estimate that the expected monthly profit is $2,782.87 with a standard deviation of $14,980.84.

b. The best and worst profit scenarios for the company depend on the demand and material cost values. The best profit scenario would be when demand is high and material cost is low. Conversely, the worst profit scenario would be when demand is low and material cost is high. Using the formula for profit, we can calculate these scenarios.

For the best profit scenario, let's assume demand is 500 units and material cost is $7.00. Plugging these values into the profit formula, we get:

profit = (15 * 500) - (7 * 500) - 2700 = $1,800

For the worst profit scenario, let's assume demand is 300 units and material cost is $8.50. Plugging these values into the profit formula, we get:

profit = (15 * 300) - (8.5 * 300) - 2700 = -$1,950

The experimental probability of an event is calculated by dividing the number of successful outcomes (in this case, hitting the target) by the total number of trials. In this scenario, Tom hits the target on 14 out of 20 tries. To find the experimental probability of hitting the target on his next try, we divide 14 by 20. The result can be expressed as a fraction, decimal, and percentage.

The experimental probability of hitting the target on the next try is found by dividing the number of successful outcomes (hitting the target) by the total number of trials. In this case, Tom hits the target on 14 out of 20 tries. Therefore, the experimental probability is:

Experimental probability = Number of successful outcomes / Total number of trials

                     = 14 / 20

                     = 7 / 10

The fraction 7/10 represents the experimental probability of hitting the target on the next try.

To express the experimental probability as a decimal, we divide the numerator by the denominator:

Decimal form = 7 / 10

            = 0.7

Thus, the experimental probability can be expressed as 0.7.

To convert the decimal into a percentage, we multiply the decimal by 100:

Percentage form = 0.7 * 100

               = 70%

Hence, the experimental probability of Tom hitting the target on his next try is 7/10, 0.7, or 70%.

Based on the given side lengths a=3 cm, b=5 cm, and c=6 cm, the triangle is a(n) scalene triangle. A scalene triangle has all sides of different lengths, which applies to this triangle with sides 3 cm, 5 cm, and 6 cm.

Triangles are described in terms of their sides and angles in geometry. A closed planar three-sided polygon shape with three sides and three angles is known as a triangle. The lengths of the sides of a scalene triangle vary. They are not equal, and the angles have three measurements. However, it still has a 180° angle sum, just like all triangles.

A scalene triangle is a triangle with three different side lengths and three different angle measurements. The total of all internal angles, however, is always equal to 180 degrees. As a result, it satisfies the triangle's condition of angle sum.

The equation of line passing through the points (1,1), (2,2), (3,3), and (4,4) is y=x.

The points (1, 1), (2, 2), (3, 3), and (4, 4) all lie on the same line, which means that we can find the equation of the line using any two of these points.

Let's use the first and last points, (1, 1) and (4, 4), respectively. We can find the slope of the line using the formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (1, 1) and (x2, y2) = (4, 4)

slope = (4 - 1) / (4 - 1) = 1

Now that we know the slope of the line, we can use the point-slope form of the equation of a line to find the equation:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is one of the points on the line. Let's use the point (1, 1):

y - 1 = 1(x - 1)

y - 1 = x - 1

y = x

The equation of the line tangent to the cost function at q= 130 is y = -80x + 10550

To find the equation of the line tangent to the cost function at q = 130, we need to calculate the slope of the cost function at that point. This is done by taking the derivative of the cost function with respect to q and evaluating it at q = 130.

The derivative of the cost function is given by: cost'(q) = 50 - q. Evaluating this at q = 130 gives us a slope of -80. Therefore, the equation of the tangent line is given by:

y = mx + b, where m is the slope and b is the y-intercept. Substituting m = -80 and (130, cost(130)) = (130, 4550) as the point on the line, we get:

y = -80x + 10550

This means that at q = 130, the cost of producing one additional gizmo is $80. The y-intercept of 10550 represents the total cost of producing 130 gizmos.
