The equation y=9x represents the total cost y for x movie tickets. A. In this situation, which quantity is dependent and which is
independent? Justify your answer.

B. Eight friends want to go see a movie. what would the total cost be, explain how u found the answer.

A) y or total cost is the dependent variable and x which is the number of movie tickets is the independent variable. Y is called dependent because its value depends on the value of x.

B) So 8 is the number of tickets which is X. So x=8. The total cost y will be: 8x9= 72

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

i think the amount would be $140.62
