Answer:
Inequality: 22 + 5x ≥ 59
Minimum amount: 7.4
Realistic number: 8
Represented on a graph: I think it would look like a vertical line starting at the x value of 8, and continue right forever
Step-by-step explanation:
22 because that's how much she has already, 5x will represent her earnings relative to the number of driveways she pressure washes, and greater than or equal to 59 because she needs $59 or more to buy the video game.
22 + 5x ≥ 59 (subtract 22 from each side)
5x ≥ 37 (divide each side by 5)
x ≥ 7.4

Answer: a. and b.
.
Step-by-step explanation:
Let as consider,
Volume (in gallons) of water in the container = v
The number of minutes = t
(a)
From the given graph it is clear that the line passing through the points (0,0) and (3,2). So, the equation of line is
Therefore, the required formula is .
(b)
We have,
Multiply both sides by 3/2.
Therefore, the required formula is .
