Oh this is a great question. For future reference, the formula for this would be called an exponential growth or decay function, here it Is;
Y = a( 1+r )ˣ or Y = a( 1 - r )ˣ 
the answer could be found by plugging your numbers into these equations
For example: 
Y = 15,250 ( 1 - .075)⁶ 
A value = starting value of object
R value= decimal equivalent of percent increase or decrease
x value = number of years it has been

Z1 and Z2 are complementary. The mZ1 = 25°. What is the mZ2?​
Elina [12.6K]

Answer:

<h2>65°</h2>

Step-by-step explanation:

Complementary means that the two angles add to 90 degrees. Since we know the measure of one angle, we will subtract 25 from 90 to get 65 degrees for angle 2.

How do I solve this equation? I need a refresher on Algebra.
yaroslaw [1]
These equations seem tricky, but aren't as hard as you think. Just solve it like you are regularly adding fractions.

Your common denominator is 9x + 9, so

1/(9x+9)  =  36/(9x + 9)   -    (5x + 5)/9

1 - 36 + 5x + 5 / 9x - 9
30x - 30/9x - 9
10x-10/3x - 3
10(x-1)/3(x-1)
10/3

Hope this helped!
