True or false, if false what would the correct term be?

True

An example would be the vector <x,y> = <10,7> which says to add 10 to the x coordinate and add 7 to the y coordinate. Put another way: we shift 10 units to the right and 7 units up.

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms
