Answer:
b
Step-by-step explanation:
In y=mx+b form, the b is the y-intercept, therefore where the line crosses the y-axis on the graph. In this graph, the line crosses the y-axis at 100. This means that the "b" value is 100. So far, our equation is y=mx+100.
Next, to find m, you go to any other point on the graph and see how much units (rise over run) you went to get there. I picked the point (2,150), You can see that it took me 1 unit up and 2 units to the right to get to that point, leading us to believe the slope is 1/2.
Finally, put everything together and you get the answer of y=1/2x+100 (the letters do not matter) :)

What is compound interest?</h3>
Compound interest is the addition of interest to the principal sum of a loan or deposit.
C.I. = Amount - Principle
Amount is given as-
A = P {1 + (r/n)}^(nt)
where A is the final amount
P is the initial principle amount
r is the interest rate
t is the time period elapsed
n is number of times interest applied per time period
Now it is given that
P = $5000
r = 5.3%
n = 1 years, since its annually
t = 4 years
⇒ A = P {1 + (r/n)}^(nt)
⇒ A = 5000 {1 + (5.3/100*1)}^(4*1)
⇒ A = 5000 {1 + (0.053)}^(4)
⇒ A = 5000 {1.053}^(4)
⇒ A = 5000 * 1.23
⇒ A = $6147.28
⇒ A ≈ $6147
Hence,Isabella will have $6147 after 4years.

Answer: 2
Step-by-step explanation:
100 + 84s = 66 + 101s
34 = 17s
s = 2
The coordinates of image of vertex D after a reflection across the x-axis is (5, 3).
Then, the number must be greatest in the series.
