Answers to numbers 2 and 3

For both of them you just make them into fraction.
For #2
$\frac{36}{120}$
and then you simplify it
36. ÷12 3
-----. =. --------
120. ÷12 10
After this you want to change the fraction to a percentage.Percentage are out of 100

so you simply will multiply by 10 to the top and bottom
3. 30
----. * 10 =. -----. = 30%
10. 100

The answer is 30%

For number #3
you simply put 63 over 240
63
-----
240
$63 \div 3= 21$
$240 \div 3 = 80$
$\frac{21}{80}$
21
----
80
is that answer because it can't be simplified
after that

Given the function y=log3(x+2)-2. List the transformations

slava [35]

Answer:

Exponential transformation.

Step-by-step explanation:

y = log_3 (x + 3) - 2

To transform this into exponential, we have:

Adding 2 to both sides

y + 2 = log_3 (x + 3)

3^(y + 2) = x + 3

x = 3^(y + 2) - 3
