In 1980, wind turbines in Europe generated about 5 gigawatt-hours of energy. Over the next 15 years, the amount of energy increased about 59% (each year). How many gigawatt-hours were generated
To solve this equation we must first plug in 5 for x.

<span> (5 - 4x)
</span>↓

(5 - 4 · 5)
The next step would be to multiply 4 by 5 to get rid of the parenthesis within our main parenthesis.

(5 - 4 · 5)

(5 - 20)
The next step would be to subtract both of the numbers within the parenthesis.

(-15)
Now we must multiply.
-

· 15 = -

-

Now we simplify our answer to get our final answer.
-5
I would think so since you have to weigh each person and then add all the weights together and then divide this number by the total number of people weighed.
Would probably mostly hinge on the actual weighing part I think for the data gathering.
Answer:
11
Step-by-step explanation:
When you plug in -2 for x you get -4(-2) +3
8 +3 = 11
F(-2)=11
Hope this helps, have a nice day
