Hello!
Set the equation to show equal 15h+75=225.
Solve for h which h=10
Have a great day!

225 = 15h + 75
150 = 15h
10=h

<h3>Slope = 10</h3><h3>y intercept at (0,750)</h3><h3>x intercept at (-75, 0)</h3>

=====================================

Explanation:

The function f(x) = 10x+750 is the same as y = 10x+750

It is in the form y = mx+b where m = 10 is the slope and b = 750 is the y intercept. So that covers the first two parts of the answer.

The x intercept is found by replacing y with 0, then solving for x like shown below

y = 10x + 750

0 = 10x + 750

10x + 750 = 0

10x = -750 ....... subtract 750 from both sides

x = -750/10 .... divide both sides by 10

x = -75

So x = -75 plugged into the function leads to y = 0

Meaning that x = -75 and y = 0 pair up together to get the point (-75,0) which is the x intercept. This is the location where the line crosses the x axis.

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 2 units,
Serggg [28]

Answer:

2

Step-by-step explanation:

he value of K would be 2 because the function f(x) is the equation of a line. K is represented as the y-intercept. When a line is shifted down 2 units, the y-intercept also gets shifted down 2 units. In f(x) the y-intercept is zero. So the difference would be 2 units
