5:
A function follows the rule y = -75 - 5x. When the function's output is 25, the equation is 25 = -75 - 5x.

What is the function input when the output is 25?


20
-20
10
-10

6:
Which of the following expressions could be interpreted as "a number times negative seven added to five equals two"?


x - 7 + 5 = 2
5 + 7x = 2
-7x - 5 = 2
5 - 7x = 2

Answer 1

1) -5 + w/3 = -1
w/3 = -1 + 5
w = 4*3
w = 12

2) 24-3x = -27
-3x = -27 - 24
3x = 51
x = 51/3
x = 17

3) -17 + n/5 = 33
n/5 = 33 + 17
n = 50 * 5
n = 250

4) A) 3m + 2 = -10

5) 25 = -75 - 5x
-5x = 25 + 75
x = 100 / -5
x = -20

6) D) 5 - 7x = 2

Hope this helps!
