The equation y = mx + b is used to express the equation of a line. Which solution is a correct way to solve this equation for x

in terms of y?

By first subtraction b and then dividing by m, the solution of the linear equation for x is:

(y - b)/m = x

<h3>How to solve the linear equation for x?</h3>

Here we have a linear equation that defines the variable y in terms of the variable x:

y = m*x + b

Where m and b are real numbers.

Now we want to find x in terms of the variable y, this means that we need to isolate the variable x.

if first we subtract b in both sides, we get:

y - b = m*x + b - b

y - b = m*x

If now we divide both sides by m, we get:

(y - b)/m = m*x/m

(y - b)/m = x

This is the linear equation solved for x.

Based on the diagram below, what is the measure of arc DC ?
emmainna [20.7K]

Given:

A diagram of a circle O, arc(AB)=y^\circ, arc(CD)=(80+y)^\circ.

To find:

The measure of arc DC.

Solution:

According to the angle of intersecting chords theorem:

Angle at intersection of chords = Half of the sum of intercepted arcs.

Let \theta be the angle between the intersection of chords AC and BD.

\theta +112^\circ=180^\circ      (Linear pair)

\theta =180^\circ-112^\circ

\theta =68^\circ

Using the angle of intersecting chords theorem, we get

\theta=\dfrac{arc(AB)+arc(CD)}{2}

68^\circ =\dfrac{y^\circ+(80+y)^\circ}{2}

136^\circ =(80+2y)^\circ

On simplification, we get

136=80+2y

136-80=2y

56=2y

Divide both sides by 2.

28=y

Now,

arc(DC)=(80+y)^\circ

arc(DC)=(80+28)^\circ

arc(DC)=108^\circ

Therefore, the correct option is C.
