Select the correct answer. what is the solution set of y = x2 2x 7 and y = x 7? a. {(0, 7), (-1, 6)} b. {(0, 7), (-7, 0)} c. {(0
Kaylis [27]

Answer:

a. {(0, 7), (-1, 6)}

Step-by-step explanation:

y = x^{2} +2x+7\\y=x+7

subtract the equations

y = x^{2} +2x+7 \\-       \ \ \ \ \  y=x+7\\y - y =x^{2} +2x+7-(x+7)\\0=x^{2} +x\\x = 0 \ and \ x= -1

for y = x^{2} +2x+7, substitute x = 0

y = (0)^{2} +2(0)+7\\y = 0 +0+7\\y=7

for y = x^{2} +2x+7, substitute x = 0

y = (-1)^{2} +2(-1)+7\\y = 1 -2+7\\y=6
