Answer:

The answer to question 14 is (6, 5), and the answer to question 15 is D) x = -2 and y = 1.

Step-by-step explanation:

Question 14 explanation: Because each line on the graph represents a different function, that means that the point where they intersect is the answer, as the point both appear on the equations y = \frac{1}{2} x+2 and y=x-1. Since the two equations' point of intersection is (6, 5), that means the solution to the system of equations is the point (6, 5).

Question 15 explanation: The solution to the system of equations 3x+4y=-2 and 2x-4y=-8 would be the x and y values that satisfy both equations. If you select the pair on selection D, you'll find that it's valid. 3(-2)+4(1)=-2 ⇒ -6+4=-2 ⇒ -2 = -2, which is true, so choice D works for the first equation. 2(-2)-4(1)=-8 ⇒ -4-4=-8 ⇒ -8=-8, which is also true. This means that x = -2 and y = 1 is the solution to the system of equations, making choice D the correct answer.

Express all possible lengths for this scrap as a compound inequality will be L ≤ 24.

<h3>What is inequality?</h3>

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

To repair a leak a plumber needs a pipe that is within 3/4 of an inch of 32 inches.

⇒ 3/4 x 32

⇒ 24

He already has a 48-inch pipe.

Let the variable L represents the length of the extra (scrap) that is removed from the 48-inch pipe will be

Then express all possible lengths for this scrap as a compound inequality will be

L + 24 ≤ 48

       L ≤ 48 - 24

       L ≤ 24

More about the inequality link is given below.

For brainiest:):):):):):):):):)
Bond [772]

Answer: $7,488

Step-by-step explanation:

For answer B:

The formula for the new balance would be A=P(1 + r)t

A = new balance

P = principal balance -> $900

r = rate (in decimal form)

t = time in years -> 8 years

To find the rate, convert 4% to decimal  

4/100 = 0.04

A=P(1+ r)t  

A=900(1+0.04)8

A=900(1.04)8

A=$7,488
