Which of the following must be TRUE?
O ADM ME DE
OB
(DE)
DM
OC DM + ME
DE
OD DM ME

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
