Answer:
So ordered pair a is (2,11)
Step-by-step explanation:
We are given
a = b+c
and ordered pair b =(6,3) and ordered pair c =(-4,8)
Putting values of b and c in the given equation and adding x and y coordinates of b and c we can find ordered pair a.
a=(6,3)+(-4,8)
a =(6-4,3+8)
a =(2,11)
So ordered pair a is (2,11)

B.
Step-by-step explanation:
Answer:
-13,-7,-3,0,3
-9,-4,-6,3,8
Step-by-step explanation:
(2n - 9) - 5(-2.4n + 4) =
The first set of parentheses is unnecessary, so we just drop them.
= 2n - 9 - 5(-2.4n + 4)
Now we distribute -5 by the second set of parentheses. Each term in the parentehses is multiplied by -5.
= 2n - 9 + 12n - 20
Now we combine like terms.
= 2n + 12n - 9 - 20
= 14n - 29
