Using the question from above-- The Wright family is trying to take their whole family to the aquarium. Adult tickets are $15.88 and children's tickets are 9.44. If
they want to spend no more than $100 and there are 2 adults and 5 children, will
they be able to go? Now that we know they will be able to go, how much will they
have left over from the $100?

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

step-by-step explanation:

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
