Answer:
There is 1 solution
Step-by-step explanation:
y = -3 (x+1) ^2
Using the zero product property
0 = -3 (x+1) ^2
Divide by -3
0 = (x+1) ^2
Take the square root of each side
sqrt(0) = sqrt( (x+1) ^2)
0 = x+1
Subtract 1 from each side
-1 =x

Answer:
Step-by-step explanation:
I dont know wish I could help, srry.
-5y+8=-3y+10
-5y+3y=10-8
-2y=2
-2y/-2=2/-2
y=-1
I grouped the alike variable to one side, and the number to the other side, added and subtracted it, divided both sides by -2, and got -1
Answer:
Step-by-step explanation:
We have three similar triangles:
therefore the sides are in proportion:
We have AD = a, CD = 16 and BD = 4. Substitute:
<em>cross multiply</em>
and other proportion:
We have AB = b, BC = 16 + 4 = 20 and BD = 4. Substitute:
<em>cross multiply</em>
