Answer:

Your answer is C. y= \sqrt[7]{\frac{x}{8} }

Step-by-step explanation:

f(x)=8x^7\\y = 8x^7

switch y and x to for inverse.

x = 8y^2

Now solve y by itself.

x=8y^7\\\frac{x}{8}=y^7\\ \sqrt[7]{\frac{x}{8} } =y

The sum of John’s and Matt’s ages is 42. The difference of their ages is 6. If Matt is older than John, what are their ages? Mat
jasenka [17]
Matt is 24 and John is 18. 24 - 18 is 6. And 24 + 18 would equal 42.

John Sells Hamburgers For $3 Each and cheeseburgers for $3.50 each. One afternoon, he sells a total of 24 burgers for $79. How M
Alexxx [7]
Let the hamburgers be x and cheese burgers be y.

x + y = 24
3x + 3.5 y = 79

x = 24 - y.

Substituting the value of x,

3( 24 - y) + 3.5 y = 79

 72- 3y + 3.5 y = 79
72 + 0.5 y = 79

0.5y = 79 - 72 = 7
1/2 y = 7

thus, y = 7 * 2 = 14

Substituting the value for x,

x + y = 24
x + 14 = 24
x = 24-14 = 10
Thus, x = 10.

Thus, she sold 10 hamburgers and 14 cheeseburgers
