N=number of African animals in the zoo;
we suggest this equation:
172=45+n/2
Least common multiple=2
172*2=45*2+n
344=90+n
n=344-90
n=254
Answer: there are 254 African animals in the zoo.
Answer:

Step-by-step explanation:
Answer:
The price of a game is 
Step-by-step explanation:
Let
x ----> the list price of a game
Remember that

To find out the price of a game that's been discounted 18% off its list price, multiply the list price by the number 0.82
so

<h3>
Answer:</h3>
- d. The y-intercept is 1 space higher.
- a. 9 to the power of -1/2
<h3>
Step-by-step explanation:</h3>
1. Changing f(x) to f(x) + 1 adds 1 to every output value of the function, moving that value "1 space higher". This is true for the y-intercept, too.
___
2. The rules of exponents apply:
- a^b · a^c = a^(b+c)
- 1/a^b = a^-b
You apparently want to simplify ...
... 9^(1/4) × 9^(1/2) / 9^(5/4)
... = 9^(1/4 + 1/2 - 5/4)
... = 9^((1+2-5)/4)
... = 9^(-2/4) = 9^(-1/2)
