Question

number line:
inequality notation: x < 4
answer attempt 1 out of 2
x + 3 < 7

Explanation:

Step1: Solve the inequality \(x + 3<7\)

Subtract 3 from both sides of the inequality.
\(x+3 - 3<7 - 3\)
\(x<4\)

Step2: Graph \(x < 4\) on the number line

Since \(x\) is less than 4 (not less than or equal to 4), we use an open - circle at \(x = 4\) and draw an arrow to the left (towards the smaller numbers).

Answer:

The inequality notation is \(x<4\). On the number line, we have an open - circle at \(4\) and an arrow pointing to the left.
