100 ! which expression is equivalent to 1/3(4−5x−1) ? −5x+3 −5/3x−1 −5/3x+1 −5x+1/3

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

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
