How many solutions does the following equation have ?<br> −3x+9−2x=−12−5x
nasty-shy [4]

\text{Solve for x:}\\\\-3x+9-2x=-12-5x\\\\\text{Combine like terms}\\\\-5x+9=-12-5x\\\\\text{Add 5x to both sides}\\\\9=-12\\\\\text{Since that's not valid, there would be no solutions}\\\\\boxed{\text{No solutions}}

erik [133]
If s is the Riley`s sister`s age and Riley is 3 years older so Riley`s age is:
s/3 so the sum of their ages is:
s + s/3 = 4s/3 :)))

Given the sequence below, and that sequence has a domain of n 2 1, find the fifth
solmaris [256]

The fifth term of f(n) = n² - 3 is 22

\texttt{ }

<h3>Further explanation</h3>

Firstly , let us learn about types of sequence in mathematics.

Arithmetic Progression is a sequence of numbers in which each of adjacent numbers have a constant difference.

\boxed{T_n = a + (n-1)d}

\boxed{S_n = \frac{1}{2}n ( 2a + (n-1)d )}

<em>Tn = n-th term of the sequence</em>

<em>Sn = sum of the first n numbers of the sequence</em>

<em>a = the initial term of the sequence</em>

<em>d = common difference between adjacent numbers</em>

\texttt{ }

Geometric Progression is a sequence of numbers in which each of adjacent numbers have a constant ration.

\boxed{T_n = a ~ r^{n-1}}

\boxed{S_n = \frac{a( 1 - r^n ) }{1 - r}}

<em>Tn = n-th term of the sequence</em>

<em>Sn = sum of the first n numbers of the sequence</em>

<em>a = the initial term of the sequence</em>

<em>r = common ratio between adjacent numbers</em>

Let us now tackle the problem!

\texttt{ }

<u>Given:</u>

f(n) = n² - 3

<u>Asked:</u>

f(5) = ?

<u>Solution:</u>

\texttt{for } n \geq 1 :

f(n) = n^2 - 3

f(5) = 5^2 - 3

f(5) = 25 - 3

f(5) = \boxed{22}
