Answer:

Yes but there is only one way to check they are an ordered pair.

This is done by using simultaneous equations

ascending line is y = 2x + 9

descending line is y = -2x + 7

The ordered coordinates can be checked ( -4, 1)

2 (-4) + 9(1) = 1

and

-2 (4) +7 (1) = -1

sveticcg [70]

Answer:

Step-by-step explanation:

RQ < PR < PQ

TV < UV < UT

ΔPQR~ΔUTV ⇒ $\dfrac{RQ}{TV}=\dfrac{PR}{UV}$

$\dfrac{8}{x-3}=\dfrac{14}{x+6}\\\\8(x+6)=14(x-3)\\\\8x+48=14x-42\\\\48+42=14x-8x\\\\90=6x\\\\x=90:6=15$
