Answer:

x=16, y=39

Step-by-step explanation:

to solve y=2x+7

Substitute 2x+7 for y in y=3x−9

y=3x−9

( solve this like a normal problem)  

2x+7=3x−9 (Add -3x to both sides)

-x+7=-9  (Add -7 to both sides)

-x=-16 (Divide both sides by -1)

x=16

Now that you found x you can substitute this in the other problem.

y=3(16)-9

y=39

Hopefully this helped!

The y intercept would be (0,2)
and the x intercept would be (4,0)
the number in front of x in the equation y=mx+b is the way you move, rise over run, put it over one in the case y=0.5/1x+2 so you rise .5 and go the right 1

Problem 1, part (a)

<h3>Answer: False</h3>

For instance, 200 feet in real life can be reduced to scale down to say 2 inches on paper. So we have a reduction going on, and not an enlargement.

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

Problem 1, part (b)

<h3>Answer: true</h3>

This is because a scale drawing involves similar polygons. This is true whenever any dilation is applied.

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

Problem 2

I'm not sure how your teacher wanted you to answer this question. S/he didn't give you any numbers for the side lengths of the polygon. The angle measures are missing as well.
