Pretty sure the answer would be 1/A^4

**Answer:**

y = -8

**Step-by-step explanation:**

Solve as a system of equations

2x + y = -8 multiply this equation by 2

-4x + 2y = -16 Do not change

Solving: 4x + 2y = -16

<u> -4x +2y = -16 </u>

4y = -32

y = -8

2x + y = -8 Solve for x

2x = -y - 8

x = -y/2 - 8/2

x = -1/2y - 4 Substitute this into your second equation

-4x + 2y = -16

-4(-1/2y - 4) + 2y = -16

2y -16 +2y = -16

4y - 16 = -16

4y = -32

y = -8 x = -1/2(-8) -4 = 4 - 4 = 0

Checking the answer

2(0) + -8 = -8

-4(0) +2(-8) = -1 6 = 0 -16 = -16

**Answer:**

2.

**Step-by-step explanation:**

2 pennies equal 2 cents.

The volume of the cereal box in cubic inches will be 10.5 x 7.5 x 2.5 inches or 196.875 cubic inches. Volume is determined by multiplying length times width times thickness and is expressed in cubic measurements whether cubic inches, feet or meters or centimeters say.

I'm sorry if I'm wrong, but I'm trying. I think it's -10, because if you think of it, you may think that oh, it's going to be the oppisite, so I got -10. If I'm wrong, I'm very sorry.
