Answer:

d(x)^{-1}= \frac{x+6}{-2}.

Step-by-step explanation:

Given :  d(x ) = -2x - 6.

To find : What is the inverse function .

Solution : We have given that  d(x ) = -2x - 6.

Step 1 : d(x) = y

Step 2) : Inter change y and x .

x = -2y -6.

Step 3) solve for y.

On adding both side by 6.

x + 6  = -2y.

On dividing by -2 both side.

\frac{x+ 6}{-2} = y .

y = d(x)^{-1}  is inverse of d(x).

Therefore, d(x)^{-1}= \frac{x+6}{-2}.

Find the measure of the missing angles.<br> 62°<br> b\co
tiny-mole [99]

The measures of angles B and C are 118° and 62°, respectively.

<h3>What are the measures of two missing angles generated by the intersection of two lines?</h3>

A system of three angles is generated by two lines intersecting each other. In accordance with Euclidean geometry, angle C is opposite to the angle with measure 62° and angle B is supplementary to the same angle.

When two angles are opposite, then both have the same measure, and when two angles are supplementary, then the sum of their measures equals 180°. Therefore, the measures of angles B and C are 118° and 62°, respectively.
