The amount of hours you worked would be 7.5, you divide 600 by 80.
Answer:
B
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
If you're looking for direct correlation, you're looking for a proportion for the second box. So you set the ratio of 2.5:5.5 up as a fraction. 2.5/5.5 and set it equal to the second box 3/x.
2.5 = 3
5.5 x
cross multiply
16.5=2.5x
and divide
16.5/2.5 and you get your answer
The line is positive
The line is positive because it slants to the right.
It wouldve been negative if it slanted to the left.
First of all, we compute the points of interest, i.e. the points where the curve cuts the x axis: since the expression is already factored, we have

Which means that the roots are

Next, we can expand the function definition:

In this form, it is much easier to compute the derivative:

If we evaluate the derivative in the points of interest, we have

This means that we are looking for the equations of three lines, of which we know a point and the slope. The equation

is what we need. The three lines are:
This is the tangent at x = -2
This is the tangent at x = 0
This is the tangent at x = 1
