Answer: x = -3

Step-by-step explanation:

-7/-7x = 21/-7

that cancels out the -7 on the left side, and leaves us with -3 on the right side!

x = -3

Can someone solve this problem for me
Aleks [24]

Answer:

(C) 90 in^{2}

Step-by-step explanation:

The figure is a combination of two parallelograms. So, to find the area of the whole figure, all you have to do is find the area of each parallelogram separately (they happen to be the same in this problem) and then add them up. The formula for the area of a parallelogram is <u>A = base*height</u>. In each parallelogram, the base is 15 in., and the height is 3 in. Therefore, the area of each parallelogram is 45 in^{2} and the area of the whole figure is 90 in^{2}.

Hope this helps :)

Answer: y≤4x+3 and y≤-3x-5

Step-by-step explanation:

The slope of the first line is 4. The slope of (-1,-1) and (0,3) is 4. And the line passes through 3, so the y-intercept is 3.

The slope of the second line is 3. The slope of (-3,4) and (-1,-2) is -3. And the line passes through -5, so the y-intercept of the second line is -5
