4a-2=a+4
+2 to both sides
4a=a+6
-a from both sides
3a=6
If you are answering a question or about how many pages he has in his book, it is 550 pages in his book total. If it's how much longer Naoya will have to read to finish their book it is 10 hours.
What you must do in this case is to use the potential type function given in the problem:
a (b) ^ x = c
We have:
new car for $ 17,930
a = 17930
The value of the car depreciated by 19% per year
b = 1-0.19 = 0.81
the car is worth no more than $ 1,900
c = 1900
the exponential inequality is:
a (b) ^ x ≤ c
17930 (0.81) ^ x ≤ 1900
Answer:
the exponential inequality is:
17930 (0.81) ^ x ≤ 1900
where
x: number of years
The percent of change=the amount of change/the starting number
in this case, the amount of change is 36-6=30
the starting number is 6
the percent of change is therefore: 30/6=5=500%
Answer:
3850 is the answer ur looking for
