Answer:
y = -5/9x + 4.1
(try doing this yourself first with different points to make sure this is the right answer, because im to lazy to check myself but ill try checking D:)
Step-by-step explanation:
first you have to find the slope . to do this use the equation y2 - y1/ x2 - x1
so write as -2 - 3/ -7 - 2 is equal to -5/-9
so now write y = -5/9x + b
we must now find the y-intercept so substitute one of the points given. lets substitute 2,3 it looks easier. So it will look like 3 = -5/9(2) + b
3 = -5/9(2) + b
3 = -10/9 + b
b = 3 + 10/9
b = 4.111111
um just round to the tenth place
<h3>Answer: $26.62 </h3>
============================
Work Shown:
P = 20 is the amount deposited
r = 0.10 is the decimal form of the 10% interest rate
n = 1 means we compound 1 time per year (annually)
t = 3 is the number of years
Plug those four values into the compound interest formula below
A = P*(1+r/n)^(n*t)
A = 20*(1+0.1/1)^(1*3)
A = 20*(1+0.1)^(3)
A = 20*(1.1)^(3)
A = 20*1.331
A = 26.62
Answer:
$41.31
Step-by-step explanation:
45 times 0.15 = 6.75
45 - 6.75 = 38.25
38.25 times 1.08 = 41.31
