Answer:
(d + 3) would be 10
Step-by-step explanation:
<u>Step 1: Distribute</u>



<u>Step 2: Subtract 13.5 from both sides</u>


<u>Step 3: Divide both sides by 4.5</u>


<u>Step 4: Determine what (d+3) is</u>



Answer: (d + 3) would be 10
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)
