Answer:
3 and a half hours
Step-by-step explanation:
y=mx+b
$30.50=$8x+$2.50
$30.50-$2.50=$8x+$2.50-$2.50
$28=$8x
$28/$8=$8x/$8
x=3.5 hours
F(x)=2x(2)−96
Step 1: Add -4x to both sides.
xf+ −4x = 4x−96+ −4x
xf −4x= −96
Step 2: Factor out variable x.
x(f−4)= −96
Step 3: Divide both sides by f-4.
x(f−4)/ f−4 = −96/ f−4
x= −96/f−4
Answer:
x= −96/ f−4

Answer:
5
Step-by-step explanation:
Add the latter two equations and you get ...
(a +b) +(a -b) = (7) +(3)
2a = 10 . . . . . . . . . . . . . . . simplify
a = 5 . . . . . . . divide by 2
Sorry...I dont understand......
12 would be the y intercept because x is 0 and y is 12
