Answer:
<h2>
88859.375 & f(n)= 28000(0.75)×</h2>
Step-by-step explanation:
using the information on the problem a function can can be made
f(n)= 28000(0.75)×
where x is the amount of years
plug in 4 for x in the equation to get
f(4)=8859.375

n=number of nickles
q=number of quarters
d=number of dimes
4 more dmes than nickles, 3 more quarters than dimes
d+4=n
q=3+d
total value is 455 cents
10d+5n+25q=455
divide both sides by 5 to simplify
2d+n+5q=91
now we convert all to one coin
q=3+d and n+4=d
subsitute 3+d for q and n+4 for d
2(n+4)+n+5(3+d)=91
2(n+4)+n+5(3+n+4)=91
2(n+4)+n+5(n+7)=91
2n+8+n+5n+35=91
8n+43=91
minus 43 both sides
8n=48
divide both sides by 8
n=6
sub back
n+4=d
6+4=d
10=d
q=3+d
q=3+10
q=13
6 nickles
10 dimes
13 quarters
Answer:
m = 1
b = 0
Step-by-step explanation:
Slope(m) = ![\frac{y}{x}=\frac{1}{1}=1](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7Bx%7D%3D%5Cfrac%7B1%7D%7B1%7D%3D1)
Y-intercept(b) = 0
Equation: y = x
