Y = 500(1 + r)^x; where r is the rate and x is the number of years.
500(1 + r)^2 = 551.25
(1 + r)^2 = 551.25/500 = 1.1025
1 + r = sqrt(1.1025) = 1.05
Therefore, the equation that represents y, the value of the item after x years is
y = 500(1.05)^x
Well, it really depends on the context they are in. For instance,

is different than

or

or

They all are interpret differently. For instance, one is a line, another is a square and one is a cube.
Answer:
x
Step-by-step explanation:
x^5
---------
x^4
When we divide exponents with the same base, we can subtract the exponents
x^(5-4)
x^1
x
The unknown number is n. So n is the unknown variable in the equation.
In order to write an equation in which n is included we must know some dependence of n with other values.
We know that <span>the difference of three times a number and 44 is −19. So, we can write:
3*n-44=-19
3*n=-19+44
3*n=25
n=25/3
