Paraphin [41]

Answer: The correct answer is Choice D.

This is an example of an exponential equation. They are in the form of y=ab^x, where a is the starting value, b is the rate and x is the number of years.

Our data starts at 2500 and increases by 5%, or 100% + 5% = 1.05.

If you put them together, you have the equation y = 2500(1.05)^x, Choice D.

A number is decreased by 40% to 525. what is the original amount?

zhenek [66]

Answer:

875

Step-by-step explanation:

X = ( 525 × 100 ) ÷ 60

X = 875

N = x + y - n = 5 and part two x = u + v = o whats the answer?

Colt1911 [192]

Just substitute the value of x from second equation into first equation:
N = x + y - n = 5
N = u + v + y - n = 5
N = 0 + y - n = 5

In short, N would be equal to y - n which is still equal to 5

Hope this helps!
