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)
Answer I think that it is x times 1 times 100= altitude.
Step-by-step explanation:
400/2= 200
but if you do it 700/6
it doesn't make sense unless
2 x 1 =2
2 x 100+200
