Tay has a $30 gift card to CoffeeBucks. They spend $2.50 on a tasty beverage every school day. Tay wants to know how many beverages they can buy using the gift card. Explain why Tay’s inequality 30-2.50x0 represents this situation.

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

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
