If to= 3x+9 and tp = 42, find the value of x

O is midpoint of TP so TO  = TP

Plug in

3x+9 = 42

3x = 33

x = 11

Answer

x = 11

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
