Answer:
A
Step-by-step explanation:
when you substitute 4 in x and 3 in y, your result are 11 no 10
Add 165 to 245. That is a total of 410kWh.
245kWh is more than 50% of 410kWh.
So, according to the plan, you will pay NightTimer rate for kWh at night and DayTimer rate during the day.
The work done:

The raw, accurate, answer is that the value to pay is $22.08085.
In real terms, it is closer to your $22.08 option. That is the one I'd take.
Step 1
Find the equation of f(x)
we have the points
(-10,-6) and (0,4)
Find the slope m
The function in slope intercept form is equal to
we have
-----> the point (0,4) is the y-intercept
substitute
step 2
Find the equation of g(x)
we have the points
(-2,-6) and (0,4)
Find the slope m
The function in slope intercept form is equal to
we have
-----> the point (0,4) is the y-intercept
substitute
step 3
Find the value of k
we have
-----> equation A
-----> equation B
----> equation C
substitute equation A and equation C in equation B and solve for k
The correct answer is: -tan 32degrees
