Answer:
Option A.
Step-by-step explanation:
System of equations is
-x² + 2x + 10 = y -------(1)
and y = x + 4 ---------(2)
By substituting the value of y from equation 2 to equation 1
-x² + 2x + 10 = x + 4
-x² + 2x - x + 10 - 4 = 0
-x² + x + 6 = 0
x² - x - 6 = 0
x² - 3x + 2x - 6 = 0
x(x - 3) + 2(x + 3) = 0
(x - 3)(x + 2) = 0
x = 3, -2
Now in the given options for x = 3, -2, values of y will be = 7, 2
Option A. will be the answer.
