HELP ME! PLEASE! be for real no playing
Two similar triangles are shown on the coordinate grid:

Which set of transformations has been performed on triangle ABC to form triangle A’B’C’?

a. Dilation by a scale factor of 4 followed by reflection about the x-axis

b. Dilation by a scale factor of 2 followed by reflection about the x-axis

c. Dilation by a scale factor of 4 followed by reflection about the y-axis

d. Dilation by a scale factor of 2 followed by reflection about the y-axis

D

Step-by-step explanation: The pre image or original triangle ABC is first enlarged by a scale factor of 2. Means its each side is multiplies by 2 or we can say that each side in the new triangle A'B'C' has become 2 times the pre image.

Then afterwards, it is reflected over to y axis. When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. The new image is just the opposite image of the pre image but its enlarged.

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
