The graph is shown below.
5u - (-20u) - u - 18u + (-11u) = 10
5u + 20u - u - 18u - 11u = 10
-5u = 10
-5(-2) = 10
So, in conclusion, X, is equal to -2.
Answer:
The first part is B= -2t + 95.
Step-by-step explanation:
Every hour the battery drops by 2 so the equation is
current battery charge= (time)(-2)+(starting battery charge)
