Lucy's goal for her cycling class at the gym is to burn 450 calories in one hour. The number of calories, she actually bums in one hour varies from her goal by no more than 45 calories. Which inequality represents this scenario?

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

i believe so, according to my "strange" way of figuring out weird math problems like this.

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
