T(3,-5) ABCD = A’B’C’D’. What translates A’B’C’D’ back to ABCD?
Tom [10]

A’B’C’D’ is obtained by translating ABCD 3 units to the right (i.e. a positive translation of 3 units along the x axis) and 5 units down (i.e. a negative translation of 5 units along the y axis).

So, in order to go back to ABCD, we have to invert both translation: we have to go 3 units to the left (i.e. a negative translation of 3 units along the x axis) and 5 units up (i.e. a positive translation of 5 units along the y axis).

What is the definition of a unit rate?
Arada [10]
When rates are expressed as a quantity of 1, such as 2 feet per second<span> or </span>5 miles per hour<span>, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.</span>

Can someone tell me if I did this right? If it's wrong can you tell me how to do it step by step? Thanks
Lesechka [4]

Hi there!

So first off, here are little definitions you need to know in order to be able to answer your question :

<u>Constant</u> means that the rates of change are the same.

<u>Variable</u> means that the rates of change are different.


But from what I can see, you don't even need those definitions because you got both answers right!


Continue your great work! If there's anything just let me know! :)
