Answer:
17/7 (2 3/7 or 2.
428571...)
Step-by-step explanation:
f(x) = 4x-2
Find f(5)
- f(5) = 4(5)-3
- f(5) = 20-3
- f(5) = 17
g(x) = -2x+1
Find g(-3)
- g(-3) = -2(-3)+1
- g(-3) = 6+1
- g(-3) = 7
Find f(5)/g(-3)
- f(5)/g(-3)
- 17/7 (2 3/7 or 2.
428571...)
P is the cost of a pound of peanuts and F is the cost of a pound of dried fruit
0.5p+0.75f=6.5
0.75p+0.25f=4.5
Rearrange
0.5p=-0.75f+6.5
Simplify
P=-1.25f+13
Substitute
0.75(-1.25f+13)+0.25f=4.5
simplify
-0.9375f+9.75+0.25f=4.5
<span>-0.6875f+9.75=4.5
</span>-0.6875f=-5.25
f=7.636364
Round
F=$<span>7.64 per pound
</span>
Plug in
0.75p+0.25(7.64)=4.5
Simplify
0.75p+<span>1.91=4.5
0.75p=</span><span>2.59
</span>p=3.453333
Round
P=$3.45 per pound of peanuts
Final
P=$3.45 per pound of peanuts
F=$7.64 per pound of dried fruit
