X^2-9x=-8
x^2-9x+8=-8+8
x^2-9x+8=0
(x-8)(x-1)=0
x-8=0
x-8+8=0+8
x=8
x-1=0
x-1+1=0+1
x=1
There are 2 solutions, which are 1 and 8
Answer:
40--C A ---is not[figure it out in your own words,your teacher might suspect something] and B---times 40
Step-by-step explanation:
b--40+40=80 80+40=120 and 120+40=160 A=subtract 40 from all the other answers such as 40-160=120 40-120=80 and 40-80=40

Answer:
Step-by-step explanation:
3y + 39 = 33
3y = -6
y = -2
1/4(-2)= -2/4 = -1/2
5x + 4 < 29
5x < 29 - 4
5x < 25
x < 25/5
x < 5
solution set is { 3,4 }
