54
a rule I follow:
same signs positive,
different signs negative.
-9 * -3 = 27
27 + 27 = 54
We must take into account the following change of units:

Applying the change of units we have that the electric consumption for 1 year is given by:

Then, the total cost is given by:
Answer:

Answer:

Step-by-step explanation:
The side that is parallel to BC is EF
Find the slope of EF:

Easiest way is just put the formula in point-slope form and simplify.
Let's use point F, which is (6,2)

Simplify:

Add 2 on both sides:
