Answer:
A number line from 0 to 60 in increments of 6. A point is at 36 and a bold line starts at 36 and is pointing to the left. ⇒ last answer
Step-by-step explanation:
* <em>Lets explain how to solve the problem</em>
- <u><em>When solving an inequality, there are some important points:</em></u>
# If the inequality is x > a, then it represented on the number line by
a ray with empty small circle as end starts at a and pointed to
the right (⇒ ∞)
# If the inequality is x ≥ a, then it represented on the number line by
a ray with bold small circle as end starts at a and pointed to the
right (⇒ ∞)
# If the inequality is x < a, then it represented on the number line
by a ray with empty small circle as end starts at a and pointed to
the left (⇒ -∞)
# If the inequality is x ≤ a, then it represented on the number line by
a ray with bold small circle as end starts at a and pointed to the
left (⇒ -∞)
* <em>Lets solve the problem</em>
∵ 1/2 x ≤ 18
- Multiply both sides by 2
∴ x ≤ 36
- To represent it draw a number line from 0 to 60 and the counted
by 6 as 0, 6, 12, 18, 24, 30, 36, 42, 48, 54, 60
- Draw a ray with bold end starts at 36 and pointed to the left
∴ A number line from 0 to 60 in increments of 6. A point is at 36 and
a bold line starts at 36 and is pointing to the left.
