Answer:

Step-by-step explanation:

I just answered this for someone else... here is the same answer I gave them

QR + RS +SQ = perimeter

2(XR) + 2(YS) + QS = perimeter ( b/c multiplication is communicative SQ=QS)

2*5 + 2 * 7 + 20 = perimeter

10 + 14 + 20 = p

44 = p

Answer:

C. 4/3x - 5

Step-by-step explanation:

First, to eliminate unnecessary answers, we can find out how to make sure the line will be perpendicular to -3/4. You will know if two lines are perpendicular if the slopes are COMPLETELY opposite. For example, 4/3 is COMPLETELY opposite from -3/4.

-3/4......4/3

So, now we know we eliminated two answers. We are left with A and C.

Then, I opened an online graphing calculator and found out which one of these lines pass through (12,9). Attached is a picture proving that answer C's line crosses through this point. Please mark me Brainliest; I need it to move on in my account! =D
