EXPLANATION
Let us find the gradient of the line:
by rewriting it in the slope intercept form.
We divide through by 4 now;
This is now in the form;
where
is he slope.
This implies that the slope of the line that is perpendicular to this line will be the negative reciprocal of .
Thus the perpendicular line has slope,
.
Let the perpendicular line have equation,
When we substitute the slope we have;
We substitute the point. to find c.
We substitute c to obtain;
Or
The question is an illustration of a system of linear equations.
- The system of linear equations is:
and
- The solution to the equation is (25,500)
Let the number of miles be x.
<u>Getting trained and licensed</u>
- One time cost: $450
- Gas and Insurance: $2 per mile
So, the equation is:
<u>Delivery</u>
- First delivery: $350
- Rate: $6 per mile
So, the equation is:
Hence, the system of linear equations is:
and
To solve the equation, we equate both, as follows:
Collect like terms
Divide both sides by 4
Substitute 25 for x in
Hence, the solution to the equation is (25,500)
