To determine which graph shows the solution to the inequality 12x - 4 < 56, we first need to solve the inequality to find the value(s) that x can be.
Let's start by isolating the variable x. We'll do this by adding 4 to both sides of the inequality:
12x - 4 + 4 < 56 + 4
Simplifying, we get:
12x < 60
Next, we divide both sides of the inequality by 12 to solve for x:
(12x)/12 < 60/12
Simplifying further:
x < 5
So, the solution to the inequality is x < 5.
Now, let's examine the four graphs and determine which one represents the solution x < 5:
1. If the graph shows all the values of x less than 5, then it represents the solution.
2. If the graph shows all the values of x greater than 5, then it does not represent the solution.
3. If the graph shows all the values of x less than or equal to 5, then it does not represent the solution.
4. If the graph shows all the values of x greater than or equal to 5, then it does not represent the solution.
Based on the inequality x < 5, the correct graph would be graph number 1 because it represents all the values of x less than 5.
