The answer is D.
You have to get x by itself so add 3 to 7 that equals 10. The signs stay the same so it’s D
To find the midpoint, we first add the points of the x values (-1 and 3), which is 2. Divide that by 2 to get 1 as our x value. Repeat for the y values to get (8+4)/2=6 and our midpoint is (1, 6)
Answer:

Step-by-step explanation:
In the given image, you can observe we have two right triangles.
Also, we know by given that those triangles are similar, which means their sides are proportional and their angles are congruent.
If the triangles are similar, we can define the following proportion between sides.

Now we use the Pythagorean's Theorem to find each hypothenuse.


Therefore, the missing sides are

<u>Part</u><u> </u><u>1</u>
Subtracting 5 from both sides yields

<u>Part</u><u> </u><u>2</u>
When the output, f(x) is 2, we can substitute that in to obtain
