Answer:
adding 36
Step-by-step explanation:
should be:
y-27=x²-12x
y-27=x²-12x
+12 +12
y-15=x²+x
y-15=x³
+15 +15
y=15x³
<h3>The worth after 4 years is $ 680.24</h3>
<em><u>Solution:</u></em>
<em><u>The formula for compound interest, including principal sum, is:</u></em>

Where,
A = the future value of the investment
P = the principal investment amount
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = the time the money is invested
From given,
n = 1 ( since interest is compounded annually)
p = 500
t = 4

<em><u>Substituting the values we get,</u></em>

Thus the worth after 4 years is $ 680.24

Answer:
96
Step-by-step explanation:
Divide 64 by 2
add 32+ 64
x=96
Direct variation is y=kx, inverse variation is y=k/x....
-5y=-2x divide both sides by -5
y=2.5x
So this is a direct variation with a constant of 2.5
