3)
fixed cost =$ 99
variable cost per hour = $ 19
total cost can be given as
t = 99 + 19h
where h is number of hours vehicle used.
4) weekend daily cost is $ 29.99
total day she rented = friday + saturday + sunday = 3 days
so total rent = 29.99 × 3 = $ 89.97
Answer:
Hey there!
The first equation has no solutions, as it is parallel lines.
The second equation has infinitely many solutions, as it is basically the same line, and the two lines intersect at infinite points.
The third equation is just one solution.
Let me know if this helps :)
Slope intercept form will help you find the function of the line :) [ y = mx + b ]
at time = 0 (y-intercept) the pool is 72in deep
the pool loses 2 inches of water every 1 hour. or -2/1
so your equation is y = -2x + 72
Good Luck!
A). $2 since on the graph you look at the bottom and the numbers represent the bags of candy. So then you look at the side and see that 2 is the only one plotted to 1
This was a quadratic formula
sin is the y value
here is me solving it
