The equation in point-slope form is y - 5 = (5/3)(x + 5). The general form of the equation is 5x - 3y + 40 = 0.

To find the equation of a line parallel to the given line and passing through the point (-5,5), we can use the point-slope form of a linear equation. The point-slope form is y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line and m is the slope of the line. First, we need to find the slope of the given line, and then we can substitute the values into the point-slope form to obtain the equation. Additionally, we can convert the equation to the general form, which is Ax + By + C = 0, by rearranging the terms.

The given line has the equation 5x - 3y - 2 = 0. To find the slope of this line, we can rearrange the equation in slope-intercept form (y = mx + b), where m represents the slope. Rearranging the equation gives us:

-3y = -5x + 2

y = (5/3)x - 2/3

From the equation, we can see that the slope of the given line is 5/3. Since the line we want to find is parallel to this line, it will have the same slope.

Now, using the point-slope form with the point (-5,5) and the slope 5/3, we can write the equation:

y - 5 = (5/3)(x - (-5))

y - 5 = (5/3)(x + 5)

This is the equation of the line in point-slope form.

To convert it to general form, we can multiply through by 3 to eliminate the fraction:

3y - 15 = 5x + 25

5x - 3y + 40 = 0

This is the equation of the line in general form.

Rita's first mistake was in her attempt to simplify the equation 3�+12−12=18. She incorrectly subtracted 12 from both sides of the equation, which resulted in 3�=6 instead of 3�=18.3. The correct step would have been to subtract 12 from only the right side of the equation, resulting in 3�=6+12 or 3�=18. From there, she correctly set up the equation �=5 and calculated the solution to be 7.

This mistake is a common one, as students often mistakenly apply operations to both sides of an equation when they should only be applying them to one side.

It is important to remember the basic rules of algebra, such as the fact that whatever operation is performed to one side of the equation must also be performed to the other side in order to maintain balance. By correctly applying these rules, students can avoid making common mistakes and arrive at the correct solution.

Answer:   oof amount minutes

Step-by-step explanation:

The pool will have the same amount of water in 427 minutes.

Thus c. The pools will have the same amount of water at 427 minutes.

A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.

It is given that,

Amount of water in Pool A = 7, 646 gallons

Rate of draining of Pool A = 8 gallons per minute

Amount of water in Pool B = 8500 gallons

Rate of draining of Pool B = 10 gallons per minute

Now m the number of minutes that the pools contain the same amount of water.

Therefore amount of water in Pool A draining in m minutes,

= 7646 - (8 × m)

= 7646 - 8m          ...(i)

And amount of water in Pool B in draining m minutes,

= 8500 - (10× m)

= 8500 - 10m     ...(ii)

Equating equation (i) and (ii) we get,

7646 - 8m = 8500 - 10m

Collecting like terms we get,

10m - 8m = 8500 - 7646

Solving we get,

2m = 854

or, m = 854/2

⇒  m = 427 minutes

The pool will have the same amount of water in 427 minutes.

Thus c. The pools will have the same amount of water at 427 minutes.

The cylinder that is sliced by the plane which is not parallel to the base of the cylinder and intersects only at the lateral surface is called an ellipse.

When a cylinder with a longitudinal axis (z) is sliced at an angle to the xy plane, an elliptical shape is created.

In a circle, every plane crosses a circular cylinder perpendicularly to its axis. A plane that is neither at right angles to the axis nor parallel to it, crosses the cylinder in an elliptical shape.

b) Solving the matrix equation, we find r = 8, l = 4, and i = 3. The florist can use 8 roses, 4 lilies, and 3 irises for each centerpiece.

a) The system of linear equations representing the situation is:

r + l + i = 15 (total flowers in one centerpiece)

r = 2(l + i) (twice as many roses as irises and lilies combined)

10(2.50r + 4l + 2i) = 370 (total budget)'

Matrix equation: AX = B, where

A = [[1, 1, 1], [2, -1, -1], [25, 40, 20]],

X = [[r], [l], [i]], and

The performance is likely to increase, as the feature size will be reduced, leading to increased efficiency of the processor.

Effect of Decreasing Feature Size on Processor Performance

The performance of a processor is largely determined by its feature size. As the feature size decreases, the processor can process more information in a given time due to the increased efficiency of its components. In this case, the designer has chosen to use a manufacturing process that decreases the feature size of the processor. This means that the processor will be able to process more information in a given time, leading to an increase in performance. All else being constant, the performance of the processor is likely to increase.

Step-by-step explanation:

m1: Sides 1 and 2 are congruent so angle will be the exact same as m2:

180° - 55° = 125 | 125 / 2 = 62.5°

m2: same as m1; 62.5°

m3: equivalent to 55° due to its location

m4: angle of a line is 180° so 180° - 105° = 75°

m5: angles of triangle add to 180° so 180° - (75° + 55°) = 50°

Step-by-step explanation:

The total cost of the television is $360 if a woman bought a new color television with a $40 down payment and 16 monthly payments of $20 each.

It is defined as the amount one party needs to pay to another party as the first party borrowed an amount that will be credited by the second party. Debt occurs when one party cannot be able to purchase something under normal circumstances.

We know the formula for the monthly payment:

\(\rm Monthly \ Payment \:=\:\dfrac{\left A\left(i\right)\left(1+i\right)^{n}\right}{\left(1+i\right)^{n}-1}\)

It is given that:

A woman bought a new color television with a $40 down payment and 16 monthly payments of $20 each.

Down payment = $40

Number of months = 16

Per month payment = $20

The total cost of the television = 40 + 16(20)

The total cost of the television = 40 + 320

The total cost of the television = $360

Thus, the total cost of the television is $360 if a woman bought a new color television with a $40 down payment and 16 monthly payments of $20 each.

A company claims that its tablet computers have an average recharge time of 3 hours with a standard deviation of 1.4 hours. Using a random sample of 50 company tablet computers, a consumer group determines a mean recharge time of 2.5 hours. H0: µ = 3 Ha: µ < 3 a = 5% σ = 1.4 z* = –1.65.

Based on the given information, we can perform a one-sample z-test to determine if the sample mean of 2.5 hours is significantly different from the claimed population mean of 3 hours, with a significance level of 0.05.

The null hypothesis H0 is that the population mean recharge time µ is equal to 3 hours, and the alternative hypothesis Ha is that µ is less than 3 hours.

We will find the test statistic z using the formula

z = (x - µ) / (σ / √n)

Where x is the sample mean of 2.5 hours, µ is the population mean of 3 hours, σ is the population standard deviation of 1.4 hours, and n is the sample size of 50.

z = (2.5 - 3) / (1.4 / √50) = -2.38

The calculated test statistic z of -2.38 is less than the critical value z* of -1.65 at a significance level of 0.05, indicating that we can reject the null hypothesis H0.

Hence, we can conclude that the mean recharge time of the company tablet computers is less than 3 hours, based on the sample of 50 tablets tested by the consumer group.

a) The set of points satisfying the equation |z| = 2 is a circle with radius 2 and center at the origin.

b) The set of points satisfying the inequality |z - 2i| < 3 is an ellipse with center at 2i and semi-major axis 3.

a) The absolute value of a complex number is its distance from the origin. So, |z| = 2 means that all points satisfying this equation are 2 units away from the origin. This forms a circle with radius 2 and center at the origin.

b) The distance between a complex number z and the number 2i is |z - 2i|. So, |z - 2i| < 3 means that all points satisfying this inequality are less than 3 units away from 2i. This forms an ellipse with center at 2i and semi-major axis 3.
