In the diagram, Ray K QJKM is a straight angle.
mixas84 [53]

The true statements about the diagram given are:

3. m∠JKL = 45°

4. m∠MKQ + m∠PKQ = m∠PKM

5. PK is an angle bisector

<h3>What is an Angle Bisector?</h3>

An angle bisector is a segment that divides a given angle into two parts that are congruent to each other.

The missing part of the question is in the image attached below.

In the image given, PK bisects the straight angle JKM since angles JKP and MKP both equal 90 degrees (right angle).

Therefore, m∠JKL = m∠PKL = 45°

m∠MKQ + m∠PKQ = m∠PKM based on the angle addition theorem.

Therefore, the true statements are:

3. m∠JKL = 45°

4. m∠MKQ + m∠PKQ = m∠PKM

5. PK is an angle bisector

(see image attached below)

Math standard form. help!
Dennis_Churaev [7]

Answer:

y=mx+b is slope-intercept form

Ax+By=C is standard form.

IN y=mx+b, m represents the slope and B represents the y intercept.

To switch from standard form to slope-intercept form all we need to do is get y alone. thats it. By folowing these steps:

-6x+5y=-30

-6x+6x+5y=-30+6x - this cancels the x on the left side of the equation bringing us one step closer to getting y alone

5y=-30+6x

5y / 5=(-30+6x) / 5 -this last step leaves y alone and brings us to slope intercept form.

y=-6+30x

y=30x-6 - i switched the 30x and 6 because y=mx+b not y=b+mx

y=30x-6

SInce m represents the slope and b represents the y itnercept, 30 is the slope and -6 is the y intercept

30=m(slope)

-6=b(y-intercept)

Btw because the slope is 30 it means the line with point like so: / since it has a positive slope.

Hope this helps!
