Answer:

Step-by-step explanation:
Slope intercept form :
y = mx + b
m is the slope
b is the y-intercept
Let's look for m, use the formula
to determine it.


Now find b, we simply need to plug in one of our coordinates to get our answer.
(12, -9)

Solve for b :
-9 = -6 + b
-3 = b
b = -3
Our slope intercept is :

Answer:
4,250,000 riyals
Step-by-step explanation:
The total cost of drilling a 500-meter well is the sum of fixed costs (1,000,000 riyals) and variable costs.
By integrating the marginal cost function we get the variable costs function. Evaluating the variable costs function from 0 to 500 meters, gives us the total variable cost.

Total cost of drilling is:

Let's call x1: The rate per hour of the number one mechanic. X2: The rate per hour of mechanic number two. The first thing you should do is identify the system of equations that best describes the problem. In this case it is a system of 2 equations with two unknowns which when solved gives a total of x1 = 85 $ / h and x2 = 50 $ / h. Attached solution.
