| x-3 | &lt; x-3<br><br> can someone give a step by step process on how to do this?
statuscvo [17]

Answer:

There are no solutions to the inequality.

Step-by-step explanation:

|x - 3| < x – 3

1. Separate the inequality into two separate ones.

(1) x – 3 < x – 3

(2) x – 3 < -(x – 3)  

2. Solve each equation separately

(a) Equation (1)

\begin{array}{rcl}x - 3 & < & x - 3\\x & < & x\\\end{array}\\\text{This is impossible. No solutions exist.}

(b) Equation (2)

\begin{array}{rcl}x - 3 & < & -(x - 3)\\x - 3 & < & -x + 3\\x &

For example, if x = 0, we get  

|0 - 3| < 0 - 3 or

3 < -3

What is the zero of the function below?<br> f(1) = 3v1 + 3 - 6
Reika [66]

Answer:

v1 = 1

Step-by-step explanation:

Solve for v1:

3 v1 - 3 = 0

Add 3 to both sides:

3 v1 + (3 - 3) = 3

3 - 3 = 0:

3 v1 = 3

Divide both sides of 3 v1 = 3 by 3:

(3 v1)/3 = 3/3

3/3 = 1:

v1 = 3/3

3/3 = 1:

Answer: v1 = 1
