Which equation shows a correct relation for triangle RSQ? sin(Q) = sin(R)
sin(Q) = cos(R)
tan(Q) = cos(R)
tan(Q) = sin(R)

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

i think c. but don't trust it.

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

first one because it can't have a fraction in it
