True. The image of a translation is always congruent to the pre-image.

Proof: every point of the pre-image is move exactly the same distance and the same direction. That means that the shape stay the same but it is just located in a different place.

Answer: 16517 dollars

Step-by-step explanation:

Given that x is the number of years after 2000.

In 2005, the number of years x = 4

Because the equation was modelled for 4 year college courses

The best estimate for the average cost of tuition in 2005 will be

ŷ = 937.98(4) + 12,764.90 

Y = 3751.92 + 12764.9

Y = 16516.82 dollars

Y = 16517 dollars
