Y=
–
48x+34
y=x2–48x–30

-8/+8

Step-by-step explanation:

First set them equal since both equal to y.

-48x+34=-48x-30

Now solve for the equation.

=64

Now take the sqaure root of both.

x=-8 or x=+8 since whatever you multiply with x^2 its positive.

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

150.6

all i did was i multiplied 5.02 by 30
