Answer:
9 yr = jennifer's age
18 yr = denise's age
12 yr = anne'e age
Step-by-step explanation:
Let x = jennifer's age
then 2x = denise's age
and x + 3 = anne'e age
x + 2x + x + 3 = 39
4x + 3 = 39
4x = 36
x = 9 yr = jennifer's age
2x = 18 yr = denise's age
x + 3 = 12 yr = anne'e age
This is an exponential growth. (typing it into a graphing tool helps)
The rate of change is the slope of your function except with exponential growth/decay you are finding the rate of change over a given interval because its not a constant slope.
Answer:
start at 0 and go up 3 and put a point (your x)
start at 0 and also go up 5 and put a point (your y)
draw LINE HORIZONALY ACROSS THE (LEFT TO RIGHT ) on each line
you should have two horizonal lines parallel

Answer: $409.55
Step-by-step explanation:
100% - 16% = 84%
84% of 487.56 = 409.5504.
Round to nearest hundredth.
$409.55
The answer would be km for the distance.
