Answer: 7 hours.
Step-by-step explanation:
The rental price is 15. Add 5 per hour (5x) and the total must be equal to $50
15+5x=50
Solve for x;
Through: (4,-4), slope= 1/4
2 answers:
First off you'll want to find the equation for a line that passes through the point (4,-4) and has a slope of 1/4. You can use the formula y=mx+b
- m is the slope, and
- b is the y-intercept
So right now we have this...y=1/4x+b.
We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (4,-4). So, why not plug in for x the number 4 and for y the number -4? This will allow us to solve for b for the particular line that passes through the point you gave!
(4,-4). y=mx+b or -4=1/4 × 4+b, or solving for b: b=-4-(1/4)(4). b=-5.
The equation of the line that passes through the point (4,-4) with a slope of 1/4
is y=1/4x-5, now you'll need to graph it, I'll just put a picture in.
Hope this helps you, have a BLESSED and wonderful day, as well as a safe one!

Given t = time and h = height
From the equation.
h is the axis od symmetry
(h, k) is the vertex.
In the equation, h is 1 and k is 16.
So the maximum value is 16 at t = 1.
The ball reaches maximum at 16 and it takes t = 1 to reach the maximum point.
