Answer:
Step-by-step explanation:
Let's start by finding Sandra's salary this year.
We are given that she saved $3,360 or 8% of her total salary this year.
Let's represent her total salary this year as "x" and set up an equation:
Note that any percentage is equivalent to that number over 100.
Multiply 100 to both sides:
Divide both sides by 8
The question states "this year her salary was $2000 more than in the previous year".
This means that her salary in the previous year is equivalent to:
For this case we have by definition, that the sum of the exterior angles of a polygon is equal to 360 degrees, only when considering only one exterior angle for each vertex of the polygon, regardless of the number of sides it possesses. That said we have to:
The external angle of a regular polygon is given by:
Where:
n: It is the number of sides of the polygon
Then, for a nonagon each exterior angle will measure:
Answer:
40 degrees each exterior angle
360 degrees the sum
So the steps to find the inverse are:
Now let's solve for y as such:
<u>Your inverse is f^-1(x) = 3/2x + 3</u>
