Answer:

x = -1, 3

Step-by-step explanation:

so what you need to do is graph each one because that's what the questions ask. One way for you to check your answer is to set the two equations equal to each other.

-x + 5 = x^2 - 3x + 2

you want to end up with one equation and having the equation equal 0. So add x to both sides to cancel out the x on the left side and then subtract 5 from both sides to cancel out the 5 on the left side.

0 = x^2 - 2x - 3

now you factor

0 = (x - 3) (x + 1)

x = -1, 3

Answer:

-9, 15

Step-by-step explanation:

Subtract 7 and multiply by 4

1/4 |2x-6| +7 = 13

1/4 |2x -6| = 6

|2x -6| = 24

2x -6 = ± 24

2x = 6 ±24

x = 3 ±12

x = -9, 15

_____

For graphing purposes, it is often convenient to rewrite the equation so the solutions are where the function is zero. Here, we can do that by subtracting 13 from the equation.

(1/4 |2x -6| +7) -13 = 0
