Question:

Triangles PQR and RST are similar right triangles.  Which proportion can be used to show that the slope of PR is equal to the slope of RT?

Step-by-step explanation:

See attachment for complete question

From the attachment, we have that:

First, we need to calculate the slope (m) of PQR

Here, we consider P and R

Where

becomes

--------- (1)

Next, we calculate the slope (m) of RST

Here, we consider R and T

Where

becomes

---------- (2)

Next, we equate (1) and (2)

From the list of given options (see attachment), option A answers the question

-50/3 is the final answer! : )

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
