find the coordinates of B" after the composition of transformations given by the rule T-2,4° ry-axis. show your work.

Step-by-step explanation:

Coordinates of point B = (-6, -7)

Transformation applied:

1. Translation T(-2, 4)

2. Reflection over y axis:

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

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
