Replace x in the equations and see which one gets the matching y :

-5(0) = 0 +1 = 1

-5(1) = -5 + 1 = -4

-5(-1) = 5 +6 = 6

The first equation works.

-x-5

- -5x^2 - 3

or

(-x-5) - (-5x^2 - 3)

First, distribute the -. So then it becomes

-x - 5 + 5x^2 + 3

Since you can't add 5x^2 to -x. You can only combine -5 and 3.

Thus it becomes

- x + 5x^2 -2

However, you order in exponents so

5x^2 - x - 2

would be the correct answer.

**Answer:**

20 cakes were sold

**Step-by-step explanation:**

I assume the question is how many cakes did they sell

set up equation

$5 per cake equals $100

5x = 100

divide both sides by 5

5x ÷ 5 = 100 ÷ 5

1x = 20

x = 20
