Tony spent $100 on books to give away as prizes to his students. at the store, he bought 4 more books than planned, spending $5 per book. which equation can be used to find the number of books he originally wanted to buy. x

Step-by-step explanation:

I'm going to assume that all books cost the same.

Let

x ------> the number of books he originally wanted to buy

we know that

-----> equation that can be used to find the number of books he originally wanted to buy

solve for x

its a trick question

step-by-step explanation:

dogs love water, just turn on the hose and it will run in circles chasing the water all day : )

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
