Answer:
42
Step-by-step explanation:
Shanice: 88
Greg: (88 - 4) ÷ 2 = 84 ÷ 2 = 42
X+y+5=0
y=-x-5
If a solution exists y=y so we can say
x^2-9x+10=-x-5 add x+5 to both sides
x^2-8x+15=0 now factor
x^2-3x-5x+15=0
x(x-3)-5(x-3)
(x-5)(x-3) so x=3 and 5, using y=-x-5
y(3)=-8 and y(5)=-10
So the two solutions are:
(3,-8) and (5,-10)
and
so

and you rationalize denominator by multiplying numerator and denominatr by
so that gives--

Your answer is
