Which of the following tables of values represent ordered pairs for the function f(x)=2x -1?

what i would say the best answer is a. 40.5

the answer is:

mean: 6

mad: 2.14

the answer is 40.

proof:

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.
