Answer:
x = 9
Step-by-step explanation:
For the lines to be parallel, then
9x + 8 and 15x - 46 are alternate angles and congruent, thus
15x - 46 = 9x + 8 ( subtract 9x from both sides )
6x - 46 = 8 ( add 46 to both sides )
6x = 54 ( divide both sides by 6 )
x = 9
Answers:
1. A.Complementary
2. C. Neither
3. B. Supplementary
4. Z= 128
Why?
The angles for #1 equal 90. For 2 it is not either option. 3 equals 180 and for 4 is 180-52 and you get 128
Answer:
The inverse will be:

Step-by-step explanation:
In order to find the inverse of the equation, we do a variable change, since we are finding the inverse, :



Now solve for y'.
First add 4 in both sides of the equation and change to the left y'.

= x + 4
Second divide by 9
/9 = (x + 4)/9
= (x + 4)/9
Now you will have to clear y, with the square root.

Simplifying terms


You can check the answer by doing the evaluation of the following equation:
(f o
) (x)
substitute the equation for y' or inverse function 
f(
)
Now substitue the value into f(x)
You will have

=x
Answer:
No
Step-by-step explanation:
Since 1/2 =0.5
0.5 > 0.4
Therefore
1/2 >0.4
