Answer:
D. 8x=16
Step-by-step explanation:
If y=2x, then
2x+3y=16
2x+3(2x) =16
2x +6x=16
8x=16
A=(-13+9)/4 = -1
a=-1
15=5m
m=3
Answer:
D. 1 and 20
Step-by-step explanation:
To solve the equation, factor the quadratic and set the factors equal to 0.
d^2 - 21d + 20 becomes (d-20)(d-1) since -1*-20 = 20 and -1+-20 = -21.
Set each equal to 0 and solve for x.
d-20 = 0 d = 20
d - 1 = 0 d = 1
