Answer:
I would believe the answer is A
1)
Let unknown number be x
3x + 5 = 65
3x = 60
x = 20
Therefore, unknown number is 20.
The slope-intercept form of a line:

m - slope
b - y-intercept
Convert 2x + 3y = -6 to the slope-intercet form:
<em>subtract 2x from both sides</em>
<em>divide both sides by 3</em>

Let
and 

We have 
Therefore

We have the equation of a line:

Put the coordinates of the point (0, 0) to the equation:


Answer: 
Answer:

Step-by-step explanation:
The area of a regular polygon is calculated using the formula;

where
is the apothem and p is the perimeter.
It was given that, the apothem is,
and the perimeter is 
We substitute into the formula to obtain;


To the nearest square inch, we have;

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.
[/tex] =
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
