Answer:
see below
Step-by-step explanation:
If the base of the exponential term is greater than 1, it represents growth.
If the base of the exponential term is less than 1, it represent decay.
If there is no exponential term, the characterization as exponential growth or decay does not apply.
If I=P*r*t, we can input 450 in for I, 3000 in for the principal (P, or the starting rate), and 3 for t=time because there were three years, resulting in 450=9000*r. Next, we can divide both sides by 9000 to get 0.05 or 5% as our answer.
Answer:
x=10 , y=20
Step-by-step explanation:
2x=x+10
2x–x=10
x=10
y=2x
y=2(10)
y=20
