Answer:

y = 1/2x + 4

Step-by-step explanation:

If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.

So solve for b: using y = mx + b

2 = 1/2(-4) + b

2 = -2 + b

4 = b

Put it all together

y = 1/2x + 4

Answer:

A. 48r² - 10r + 3

Step-by-step explanation:

Solve (6r - 1) × (-8r - 3)

1. <u>Distribute 6r and -1</u> (into -8r - 3):

-48r² - 18r + 8r + 3

2. <u>Combine like terms</u> (-18r and 8r):

-48r² - 10r + 3

So, your answer is -48r² - 10r + 3
