Answer:
Step-by-step explanation:
if t varies inversely proportional as r, then,
t ∞ 1/r
t = k.1/r
t = k/r
substitute t =6 and r = 5 into the equation above
6 = k/5
k = 5 x 6 = 30
the equation that represents this variation is given by,
t =30/r
tr = 30
when r =15,
t = 30/15
t =2

Answer:
D. 4.5%.
Step-by-step explanation:
Interest earned in 6 months = 572.6 - 560 = $12.60.
As a percentage this is (12.60 * 100) / 560
= $ 2.25%.
So the annual interest is 2 * 2.25
= 4.5%.

Answer:
y=3x+(-6)
Step-by-step explanation:
y=mx+b
b is the initial condition which means any the point where the slope crosses the y axes.
m is the growth, also known as how much y increases when x increases by 1.
