On Saturday, you drove 10 miles. On Sunday, you drove 50 miles. The number of miles drove on Sunday is what percent of the number of miles drove on Saturday? The number of miles drove on Sunday is % of the number of miles drove on Saturday. what is the percent?

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
