Answer:
(-1, 16) and (2, 10)
Step-by-step explanation:
Substituting -1 in place of x in the first equation, we have
y = (-1)²-3(-1)+12 = 1--3+12 = 1+3+12 = 4+12 = 16.
Substituting -1 in place of x in the second equation gives us
y=-2(-1)+14 = 2+14 = 16
This makes the first ordered pair (-1, 16).
Substituting 2 in place of x in the first equation gives us
y=2²-3(2)+12 = 4-6+12 = -2+12 = 10
Substituting 2 in place of x in the second equation gives us
y=-2(2)+14 = -4+14 = 10
This means the ordered pair (2, 10) is the second solution.
