Set up a system of equations.
X+y=6
Y-x =40
Substitution method.
Y=6-x
(6-x)-x =40
6-2x=40
-2x=34
X= -17
Plug it back into the equation.
-17+y=6
Y=33
(-17,33) is one of the possible answers.
Answer:
{2, 4}

Answer:
x = 3.
Step-by-step explanation:
The parabola opens downwards.
it's x = 3 (because of the (x- 3))
6.9 +3.9+7.9/2=54+27+31.5=112.5
