Solve the problem using a system of equations: The difference of the squares of two numbers is 30. The difference of the square of the first number and twice the square of the second number is 5. Enter two such numbers separated by a comma. For example −2,5. Leave the answer in radical form if applicable.

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

the answer is c
