Answer: A

Step-by-step explanation:

Distribute 3x^2 into (x +9) first:

3x^2 × x = 3x^3

3x^2 × 9 = 27x^2

Next distribute 7 into (x+9):

7 × x = 7x

7×9 = 63

Add any like terms (none in this problem)

3x^3 + 27x^2 + 7x + 63

Do FOIL. Front, outside, inside, then last. The answer you will get is A, 3x^3+27x^2+7x+63.

Answer:

A= y= -2x+7.

B= y= - $\frac{3}{2}$ x+ 6

Step-by-step explanation:

The linear equation is y=mx+b

A= y= -2x+7.

-2 represents he slope and 7 represents the y intercept.

B= y= - $\frac{3}{2}$ x+ 6

- $\frac{3}{2}$ is the slop and 6 is the y intercept.

Hope this helps :)

I think it’s positive. As it gets heavier, the cost has a positive slope, or increases. I’m not absolutely sure though
