Answer:

f(x) = 2x +1

Step-by-step explanation:

Apparently the ordered pairs are ...

(x, f(x)) = (1, 3), (2, 5), (3, 7), (4, 9)

We note that as x increases by 1, the value of f(x) increases by 2. The difference between f(x) and 2x is 3-2·1 = 1, so we have ...

f(x) -2x = 1

f(x) = 2x +1 . . . . . . add 2x

What value of X makes the equation true -7x - (-5-x) = -9(2x-1) -1

Bond [772]

Answer:

x = 1/4

Step-by-step explanation:

-7x - (-5-x) = -9(2x-1) -1

-7x + 5 + x = -18x + 9 - 1

combine like terms:

-6x + 5 = -18x + 8

add 18x to each side of the equation:

12x + 5 = 8

subtract 5 from each side:

12x = 3

divide both sides by 12:

x = 3/12 = 1/4
