-5x-4y=-8 Write a formula for f(X) in terms of x

hope its helps l got it from https://www.cymath.com/ its good for math solving.

​

f(x) = - x + 2

Step-by-step explanation:

Note that y = f(x)

Rearrange making y the subject

- 5x - 4y = - 8 ( add 5x to both sides )

- 4y = 5x - 8 ( divide terms by - 4 )

y = - x + 2 , that is

f(x) = - x + 2

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
