Jose bought 4 comic books and 2 nonfiction books. the 4 comic books cost him 8y dollars. if the cost of one nonfiction book is (3+7y)dollars more expensive than the cost of one comic book, find

write out the equation:

8y=3+7y  (I'm assuming y is the amount of comic books)
8=3+7
8=10

Obviously the equation isn't equal. The nonfiction is greater. By the way, I took out the y because I assumed that y was the amount of books and there was no need to write out 8 times one. On a test, make sure you specify this of the teacher may take off points, if she is using Common Core.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
