The difference of five times the cube of x and two times the square of x is 18

x=3√2 or x=4

Step-by-step explanation:

5*x^3-2*x^2=18

x^2(5x-2)=18

x^2=18 or 5x-2=18

x=√18 or 5x=20

x=√9*2 or x=4

x=3√2 or x=4

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
