Yes because you are simply translating the shape and moving it and not changing the shape.

Answer: Yes, they are congruent.

Step-by-step explanation:

Given: On the coordinate plane, ΔABC ≅ ΔDEF by SSS...........(1)

ΔABC translates 2 units to the left and 3 units down.

Let ΔA'B'C' be the translated image of ΔABC.

  • A translation is rigid transformation that maps every point of a figure by the same distance in a given direction.

Since, all the rigid transformations create congruent images.

Hence, ΔA'B'C'≅ΔABC.........................(2)

From (1) and (2), we have

A'B'C'≅ΔDEF   [Transitive property of equality]

Therefore, the triangles remains congruent.

A builder buys bricks at the rate of $4.50 per brick for the first 10, $3.50 per brick for the next 10, and $2.50 for any additi
iogann1982 [59]
If the first 10 bricks come out at $ 4.5, I would be spending $ 45. The other 10 bricks come out at $ 3.5 so he would be spending $ 35. Therefore, he has $ 20 available to buy bricks at $ 2.5, which would be buying 8 additional bricks. Thus, in total, with $ 100, 28 bricks were purchased.

What is the solution to this system of equations?
maksim [4K]

Answer:x=3 y=1/2

Step-by-step explanation:

x+2y=4

2x-2y=5

Add both equations together

x+2x+2y-2y=4+5

3x+0=9

3x=9

Divide both sides by 3

3x/3=9/3

x=3

Substitute x=3 in x+2y=4

x+2y=4

3+2y=4

Collect like terms

2y=4-3

2y=1

Divide both sides by 2

2y/2=1/2

y=1/2

So by hour 3 you should be at 16
