To solve the inequality \(x + 3 \leq 7\), we first subtract 3 from both sides:
\[ x \leq 7 - 3 \] \[ x \leq 4 \]
This means that the solution includes all values of \(x\) that are less than or equal to 4.
In terms of a graph on a number line:
- A closed circle should be marked at 4 to indicate that it is included in the solution.
- A line should extend to the left of 4 (toward negative infinity), indicating all numbers less than 4 are included.
Among the responses provided, the correct graph would be:
A number line with arrows at both the ends ranges from negative 10 to 10 in unit increments. A closed circle is marked on the tick line above 4. A line is drawn from 4 toward negative 10 with an arrow at the end.
This option correctly represents \(x \leq 4\).
