Step-by-step explanation:
Calculate C by adding corresponding components of A + B
C =
+ ![\left[\begin{array}{ccc}-2.5\\5\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-2.5%5C%5C5%5C%5C%5Cend%7Barray%7D%5Cright%5D)
= ![\left[\begin{array}{ccc}4-2.5\\-7.5+5\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4-2.5%5C%5C-7.5%2B5%5C%5C%5Cend%7Barray%7D%5Cright%5D)

Answer:
Yes
Step-by-step explanation:
(8,8) is a solution is y=x.
If we substitute the point into the equation, the equation is true.
(8,8) is in (x,y) format
Substitute:
y=x
8=8
LS=RS (left side equal rights side)
A) Y = 100/10^x
B) Y = 0-50x
9 2/3 - 2 8/10 = 16 13/15
