Answer:

               y=x\\\\y=\dfrac{-x+10}{x-4}

Step-by-step explanation:

Red line is increasing and for any x goes the same y, so it's y = x

The blue graph is  y=\dfrac a{x-h}+k, where h=4 and k =-1 and for x=5 also y=5

It gives:

               5=\dfrac a{5-4}+(-1)\\5=a-1\\a=6

So:

      y=\dfrac6{x-4}-1 =\dfrac6{x-4}-\dfrac{x-4}{x-4} =\dfrac{6-x+4}{x-4}=\dfrac{-x+10}{x-4}

The simplified version of this x-2z

Step-by-step explanation:

You need to start by combining like terms. You can start with the terms that have the variable x in them. By combining those terms, the equation becomes x+3y-z-3y-z.

From here, you can combine the terms 3y and -3y, which bring the equation to x-z-z.

From here, combine the terms with the variable z. This would bring the equation down too x-2z, your final answer.

<h3>Answer: C) increase from 45 degrees to 50 degrees</h3>

===============================================

Explanation:

Let's calculate the angle B based off the arcs CDF and GHJ

B = (far arc - near arc)/2

B = (arc CDF - arc GHJ)/2

B = (130 - 40)/2

B = 90/2

B = 45

----------

Now let's change GHJ to 30 degrees, while keeping the other arc the same.

B = (far arc - near arc)/2

B = (arc CDF - arc GHJ)/2

B = (130 - 30)/2

B = 100/2

B = 50

Angle B has increased from 45 degrees to 50 degrees.
