Answer: correct
Answer:
Option (2)
Step-by-step explanation:
Given inequality is,
3x + 12 ≤ 24
3x + 12 - 12 ≤ 24 - 12
3x ≤ 12

x ≤ 4
Now we can plot this inequality on a number line.
An arrow starting with a solid point from x = 4 directing towards negative infinity will be the graph on a number line.
Therefore, Option (2) will be the correct option.
5.46 to 3 sig figs means the range is {5.455,5.465} and 17.74 means the range {17.735,17.745}.
p=q²/r has a maximum value when q=5.465 and r=17.735 and a minimum value when 5.455 and r=17.745.
So the range of p is 1.6769 to 1.6840. When we have 2 decimal places we get p=1.68 which accommodates the maximum and minimum values of the range. So 2 decimal places is a suitable degree of accuracy, or we could say 3 significant figures.
