Thomas paid a one-time registration fee of $15 and $10 for each cycling class he took. Write an equation in slope- intercept form to represent this relationship.

%40

step-by-step explanation:

perimeter of the base times height

step-by-step explanation:

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
