5. A PST is the image of A PST under a dilation. The dilation has a scale factor of 3, and the center of the dilation is a point inside A PST . Which statement MUST be true? A PS is parallel to P'S
B. The lines PT and P'T' are identical.
C. The measure of ZP' is 3 times the measure of ZP.
D. PS is congruent to PS

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.

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
