Answer: -3, -5, -7 from top to bottom
Step-by-step explanation:
just plug in the x to the function f(x)=-x
which mean f(x)=-3, f(x)=-5, f(x)=-7
Given:
A plane flying a straight course observes a mountain at a bearing of 35° to the right of its course.
The distance between plan and mountain is 10 km.
A short time later, the bearing to the mountain becomes 45°.
Here NM is the distance between the plane from the mountain when the second bearing is taken.
We need to find the measure of NM.

The sum of the supplementary angles is 180 degrees.





We know that the sum of all three angles of the triangle is 180 degrees.






Consider the sine law.

Take the equation to find the measure of NM.





Hence the measure of NM is 8.1 km.
The plane is 8.1 km far from the mountain when the second bearing is taken.
The simplified equation of
is 
<h3>How to determine the simplified equation?</h3>
The complete question is added as an attachment
The equation is given as

Subtract (x - 10)^2 from both sides

Evaluate 4^2

Take the square root of both sides

Add 6 to both sides

Hence, the simplified equation of
is
