A triangle has the coordinates
fiasKO [112]

Answer:

coordinates of its image

A' = ( -4, -1)

B' =( -3, -3)

C' = ( 0, 2)

Step-by-step explanation:

Reflect in y-axis means mirror it's points in the y -axis.

This means that the x coordinate of each point, changes only. Any mirrored point in the y-axis, will change only, by multiplying the x-coordinate by -1.

(Remember, zero multiplied by -1 remains 0).

Given are these points A, B, and C.

A = (4, -1)

B = (3,-3)

C = (0, 2)

After mirroring in the y- axis you get:

A' = ( -4, -1)

B' =( -3, -3)

C' = ( 0, 2)

How do you answer this for a elimination simulatoneons equation
denis23 [38]

\it 3x+2y=14&#10;\\&#10;5x-2y=18&#10;\\&#10;------\\&#10;8x \ \ \ \ \ \ \  =32 \Rightarrow x = 32:8\Rightarrow x=4 \ \ \ (*)

\it 3x+2y=14 \stackrel{(*)}{\Longrightarrow} 3\cdot4+2y=14 \Rightarrow 12+2y=14 \Rightarrow 2y=14-12\Rightarrow &#10;\\\;\\&#10;\Rightarrow 2y=2 \Rightarrow y=2:2 \Rightarrow y=1

Therefore, the solution is:  x = 4,  y=1.
