Which ordered pair is not a solution of f(x) = 2x + 9?
(7, 23) (3, 14) (2, 13) (0, 9)

i think the answer would be c

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
