D, the first equation of the piece wise function is linear, all linear is one is to one function, and the second is essentially a log
1. write the division as a fraction
9+n/2>16 → 9+1/2n>16
2. multiply both sides of the inequality by 2
2x9+2x1/2n>2x16
3. multiply the numbers and reduce the numbers with greatest common divisor 2 (remove number 2, the common factor from equation)
18+n>32
4. move constant to the right by adding its opposite to both sides
18+n-18>32-18
5. eliminate the opposites
n>32-18
6. subtract the numbers
n>14
hope this helped!
Raise the fraction to the highest term 1/5 to 15ths is ![\frac{3}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B15%7D)
<em><u>Solution:</u></em>
Given that we have to raise the fraction to the highest term 1/5 to 15ths
To raise a fraction to higher term, first you divide the larger denominator by them smaller denominator
Then multiply both the numerator and denominator by the same number, as a result that will give a new denominator.
Let "x" be the numerator of new fraction
![\frac{1}{5} = \frac{x}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%20%3D%20%5Cfrac%7Bx%7D%7B15%7D)
To make the denominator 5 to 15 we have to multiply both numerator and denominator by 3
![\frac{1 \times 3}{5 \times 3} = \frac{3}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B1%20%5Ctimes%203%7D%7B5%20%5Ctimes%203%7D%20%3D%20%5Cfrac%7B3%7D%7B15%7D)
