Answer:
x = 9.7 (9.6875)
Step-by-step explanation:
180=6x+12+5x+13+5x
155 = 16x
9.6875 = x

Answer:
see explanation
Step-by-step explanation:
If f(x) and are inverse functions, then
f()(x) = x
Thus substitute x = (x) into f(x)
f( )
= 5 ( ) - 6
= x + 6 - 6
= x
Thus f(x) and (x) are inverse functions
Factorization involves breaking down an expression.
- The factorized expression of is
- The other factor of is
- The factorized expression of x^3 - 1 is
The sum of cubes is given as:
<u>(a) Verify the formula</u>
Expand the expression on the right-hand side
Collect like terms
The formula has been verified
<u>(b) Factorized 8x^3+ 27</u>
We have:
Express 27 as 3^3
Express 8 as 2^3
Rewrite as:
Given that:
The expression becomes
<u>(c)The other factor of 2^3 - b^3</u>
By difference of cubes, we have:
So, the equation becomes
This gives
Hence, the other factor of is
<u>(c) Factor x^3 - 1</u>
We have:
Express 1 as 1^3 in x^3 - 1
becomes
