3x + 1 = 6x - 4
-3x +4 -3x +4
5 = 3x
5/3 = x x is 5 divided by 3
Opposite sides must be parallel (arrows indicate this) and equal (set up and equation)
Answer:
Step-by-step explanation:
This is clearly a linear relationship. If Alex rented the movie for 0 days, he'd owe nothing. If he paid $6 for a 3-day rental, the slope of this line would be m = rise / run = $6/(3 days) = $2/day, which is positive.
Then the equation for this graph is C(x) = ($2/day)x, where x is the number of days for which the movie is rented.
Using this formula, we find three particular points on the graph:
(1, $2), (2, $4), (3, ($6)
3x + x =12.80
Combine like terms
4x=12.80
Divide both sides by 4 to isolate x
X=3.20
Pat has 3 times = 3.20x3= 9.60
12.80-9.60 =3.20 Jerry’s money
