Solve for x.
12x + 17 / 6x + 1

12x + 17 + 6x + 1

Reorder the terms:

17 + 12x + -6x = 77

Combine like terms: 12x + -6x = 6x

17 + 6x = 77

Solving

17 + 6x = 77

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-17' to each side of the equation.

17 + -17 + 6x = 77 + -17

Combine like terms: 17 + -17 = 0

0 + 6x = 77 + -17

6x = 77 + -17

Combine like terms: 77 + -17 = 60

6x = 60

Divide each side by '6'.

x = 10

Simplifying

x = 10

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
