Please help me with 13 and 14

Mathematics
1 answer:
Karo-lina-s [1.5K]3 years ago
4 0

Answer:

13. x = 6

14. x = 3.5

Step-by-step explanation:

13. To find x when f(x) = -17, set the equation f(x) equal to -17 and solve.

-3x + 1 = -17                    Subtract 1 from both sides

-3x = -17 - 1

-3x = -18                          Divide by -3

x = 6

14. To find x when g(x) = 31, set the equation g(x) equal to 31 and solve.

10x - 4 = 31                    Add 4 to both sides

10x = 31 + 4

10x = 35                        Divide by 10

x = 3.5
