Answer: y=12/5 and P=120
Step-by-step explanation:
Set (10y-4)=(5y+8) which makes y=12/5
Substitute y in for both PS and QR to get 20 and 20
If PQ=2PS, then 2(20)=40. Do the same for SR to also get 40
40+40+20+20=120
Answer: 1 and 4

Answer:
y=x-3
Step-by-step explanation:
To find slope, use m=y2-y1/x2-x1, using values of x and y from two different points. Once you have found slope, take another point and use the point-slope equation y-y1=m(x-x1) and substitute in slope for m and the point for x1 and y1. Isolate y by subtracting y1 from both sides.
Answer: For 1 it is A - f(x)=(x-2)(x+4) and for 2 it is C - y = 0.5x^2 + 1.5x − 5
