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:
The area of Blanket A is 18yd^2
Answer:
circumcenter
Step-by-step explanation:
The intersection of the perpendicular bisectors of a triangle is known as the <u>circumcenter</u>.
Answer:
x=3
Step-by-step explanation:
2 Subtract 44 from both sides.
y-4=2(x-3)y−4=2(x−3)
3 Divide both sides by 22.
\frac{y-4}{2}=x-3
2
y−4
=x−3
4 Add 33 to both sides.
\frac{y-4}{2}+3=x
2
y−4
+3=x
5 Switch sides.
x=\frac{y-4}{2}+3x=
2
y−4
+3
