Answer:

x=10

y=-10

Step-by-step explanation:

multiply first row by 7

14x−21y=350

​7x+8y=−10

multiply second row by 2

14x−21y=350

​14x+16y=−20

subtract the first row by the second row

−37y=370

solve for y

y=−10

substitute y=-10

14x−21×−10=350

solve for x

x=10

and thats your answer

x=10

y=-10

Soloha48 [4]

Answer:

  The volume of a cube with side length 2 is 8.

Step-by-step explanation:

The argument of the function is the side length. In v(2), the argument is 2, so the side length of the cube of interest is 2 units.

The value of the function is the volume of the cube. The value of v(2) is 8, so that is the volume of the cube whose side length is 2.
