In the middle there are 13 units away.
Let c=ice cream and p=pie
3c-20=p
p+c=500
Substitute for p.
p=130 and c=370
4p+2c=54
4p+2(21-p)=54
4p+42-2p=54
2p+42=54
2p=12
p=6
4p+2c=54
4(6)+2c=54
24+2c=54
2c=30
c=15
p=6, c=15
Answer:
f(8)=4
Step-by-step explanation:
Put the equation in y=mx+b
-3x+12y=24
Add 3x to both sides
12y=3x+24
Divide 12 on both sides
y=3/12x+2
Simplify the fraction
y=1/4x+2
Substitute 8 for x
y=1/4(8)+2
y=2+2
y=4
So, f(8)=4
Hope this helps! :)
