If y(x) = 3(x+5) +4/x, what is f(a+ 2)?

Answer:

x=4

Step-by-step explanation:

First subtract by doing 64 minus 36. You are left with 28, divide by 7 and your answer is 4.

Answer: X = 4

Step-by-step explanation:

Answer:
(3/4)*(x) = 2/3

Step-by-step explanation:
If you make an equation (3/4)*(x) = 2/3 then the x would represent how many 3/4ths will be equal to 2/3rds since multiplying by that number x represents is like adding up how many of the 3/4ths you need to equal what’s on the other side of the equals sign - so from there you just solve the equation for x..

Answer:

3 times at most

Step-by-step explanation:

\(2\frac{2}{3}\div\frac{3}{4}\)

\(\frac{8}{3}\div\frac{3}{4}\)

\(\frac{8}{3}*\frac{4}{3}\)

\(\frac{32}{9}\)

\(3\frac{5}{9}\)

Therefore, 3/4 goes into 2 2/3 three times at most  

An absolute value is the numerical value of a number without consideration of its sign. It can be represented graphically by a straight line known as a number line. Absolute value equations are equations that include absolute values of variables or unknown quantities. The following are examples of how to write an absolute value equation in the form |x-c|=d to fit the provided solution sets:

Example 1:

Solution set: {x|x≤-3 or x≥1}
Absolute value equation: |x-(-1)|=4
Explanation: -1 is the midpoint of the two ranges (-3 and 1) in the solution set. |x-(-1)|=|x+1| is the absolute value expression for the midpoint -1. The distance d from -1 to the solutions' furthest endpoints, 1 and -3, is four, hence the value of d in the absolute value equation is 4.

(c) 15i + 4b ≥ 100 inequality represents this scenario.

To represent the scenario described in the problem, we need to use an inequality that relates the amount of money Emily spends on ink and brushes to the total amount of money she has available. Let's call the amount of ink Emily buys "x" and the number of brushes "y". Then the total amount of money she spends is:

Total cost = 8x + 18y

We want to know when this total cost is less than or equal to $100, so we can write:

8x + 18y ≤ 100

This inequality means that the total cost of ink and brushes must be less than or equal to the amount of money Emily has available. Therefore, the answer is (c) 15i + 4b ≥ 100.

Correct Question :

Emily has $100 extra to spend on supplies for her T-shirt-making business. She wants to buy ink, i, which costs $8 a bottle, and ne brushes, b, which are $18 each. Which inequality below represents this scenario?

The number of pounds Kaitlin will buy

p < 5

Explanation:

Given that each pound of candy costs $6

Since Kaitlin will spend less than $30 on candy, let the number of pounds she can buy with less than $30 be p, then

6p < 30

Divide both sides by 6

p < 30/6 = 5

A true statement based on the given information is that ΔCAT and ΔDOG are similar triangles, meaning their corresponding angles are congruent and their corresponding sides are in proportion.

If all pairs of corresponding angles and sides in triangles ΔCAT and ΔDOG are congruent, it implies that the two triangles are similar. In similar triangles, the corresponding angles are congruent, and the corresponding sides are in proportion.

Based on this information, the following true statement can be made:

The ratio of the lengths of the corresponding sides in ΔCAT and ΔDOG is equal.

For example, if the corresponding sides are CA and DO, the ratio CA/DO will be equal to the ratio of the lengths of the other corresponding sides.

Answer:

1. y = 0.437798+0.829539X

2. there is a significant effect

3. 7.523

4. 41.914

5. no

6. 0.8777

Step-by-step explanation:

1.

from the regression output we have

intercept = 0.437798

slope = 0.829539

the regression line would therefore be =

y = 0.437798 + 0.829539X

2.

h0 = regression is not significant

h1: regression is significant

alpha = 0.05

p value = 0.0001

we compare p-value with alpha

0.0001<0.05

we therefore reject H0 and conclude that hours spent studying have significant effect on total points.

3.

To get standard error of estimate:

mean sum of squared error = MSE

MSE = 56.5974

y = 0.437798 + 0.829539(50)

y = 41.914

Answer:

x = 4

Step-by-step explanation:

if a line is parallel to a side of a triangle and it intersects the other two sides then id divides those sides proportionally.

DE is such a line , then

\(\frac{BD}{AD}\) = \(\frac{BE}{EC}\)  ( substitute values )

\(\frac{x+2}{x}\) = \(\frac{3}{2}\) ( cross- multiply )

3x = 2(x + 2)

3x = 2x + 4 ( subtract 2x from both sides )

x = 4

Based off of this information, it looks like there are more online shoppers than in-store shoppers, more simply because there are 4 arrays that have more online shoppers than in-store shoppers, and 3 arrays that have more in-store shoppers than online shoppers, and 1 array that has an even amount of shoppers. But if you add up the numbers for a total of 160/161, you see there are more in-store shoppers than online shoppers.

So there are more in-store shoppers total.

To determine the cost of carpeting the room, we first need to calculate the area of the room that needs to be carpeted.

The area of the room is:

A = l × w

A = 6 m × 4 m

A = 24 square meters

Next, we need to determine the area of the carpet required. Since the carpet has a width of 1.5 m, we can think of the room as being covered by a series of strips of carpet, each of width 1.5 m. We need to calculate the length of each strip and then multiply that by the width of the carpet.

The length of each strip is equal to the length of the room, which is 6 m. So, the area of each strip of carpet is:

A_strip = l × w_carpet

A_strip = 6 m × 1.5 m

A_strip = 9 square meters

To cover the entire room, we will need to use several strips of carpet. The number of strips required is the total area of the room divided by the area of each strip:

Number of strips = A / A_strip

Number of strips = 24 square meters / 9 square meters

Number of strips = 2.6667 strips

Since we cannot use a fractional number of strips, we will need to round up to 3 strips of carpet.

The total area of carpet required is the area of each strip multiplied by the number of strips:

Total area of carpet = A_strip × Number of strips

Total area of carpet = 9 square meters × 3

Total area of carpet = 27 square meters

Finally, we can calculate the cost of carpeting the room at the given rate of rupees 200 per meter:

Cost of carpeting = Total area of carpet × Cost per meter

Cost of carpeting = 27 square meters × Rs. 200 per meter

Cost of carpeting = Rs. 5,400

Therefore, the cost of carpeting the rectangular room of 6 m long and 4 m wide with the carpet of width 1.5 m at rupees 200 per meter would be Rs. 5,400.

Step-by-step explanation:

Option (b) is the correct answer: Perpendicular segments.

Perpendicular rays, perpendicular segments, perpendicular lines, and parallel lines are important concepts in geometry that describe the relationship between lines and line segments.

1. Perpendicular Rays: Perpendicular rays are two rays that intersect at point and form a right angle (90 degrees) at the point of intersection. The rays extend indefinitely in opposite directions from the point of intersection.

2. Perpendicular Segments: Perpendicular segments are line segments that intersect at a right angle. They share a common endpoint but do not extend indefinitely like rays. The right angle is formed at the point of intersection.

3. Perpendicular Lines: Perpendicular lines are lines that intersect at a right angle. They continue indefinitely in opposite directions and form four right angles at the point of intersection. Perpendicular lines are often denoted by a symbol ⊥.

4. Parallel Lines: Parallel lines are lines that never intersect. They remain equidistant from each other at all points. Parallel lines have the same slope and do not converge or diverge. In Euclidean geometry, parallel lines are denoted by a double vertical line symbol (||).

Understanding these concepts is fundamental in geometry as they help define angles, shapes, and spatial relationships. The properties of perpendicular and parallel lines play a crucial role in various geometric theorems and applications.
