Step-by-step explanation:
Answer:
x + 4 = 9 + 2x - 15
Step-by-step explanation:
Since, E is between F and G.
Therefore,
FG = EF + EG
x + 4 = 9 + 2x - 15
x + 4 = 2x - 6
4 + 6 = 2x - x
10 = x
or
x = 10
Answer:

Step-by-step explanation:
The initial number of cells = 100 and it doubles every hour.
Let the exponential function be

In 1 hour, A = 2P

Therefore, the model of the given situation is given by

If he puts in $25 every month and there are 12 months in one year, just multiply 25 by 12 to find that Maurice will save $300 a year.
