Help How do you do this one?

Step-by-step explanation:

if two chords of a circle are at equal distance from the center then they are equal.

OP=OQ

AB=CD

AB=2PB=2(3x-17)=6x-34

because perpendicular from the center on a chord bisects the chord.

6x-34=15-x

6x+x=15+34

7x=49

x=7

AB=6×7-34=42-34=8

PB=3×7-17=21-17=4

Radius of circle=√(OP²+PB²)=√(3²+4²)=√(9+16)=√(25)=5

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
