Answer:
- 11 ≤ x ≤ - 3
Step-by-step explanation:
Inequalities of the type | x | ≤ a , have a solution of the form
- a ≤ x ≤ a
Then
| x + 7 | ≤ 4
- 4 ≤ x + 7 ≤ 4 ( subtract 7 from each interval )
- 11 ≤ x ≤ - 3
At 0 hours: 24 boxes
After 1 hour: 24/2 = 12 boxes
After 2 hours: 12/2 = 6 boxes
After 3 hours: 6/2 = 3 boxes
She will have 3 boxes after 3 hours.
Hope this helps :)

x = 2
Step-by-step explanation:
i guess
I’m pretty sure it’s proportional because the line on the graph is straight.

Answer:
(b) Congruent Figures
Step-by-step explanation:
Reflections, rotations, and translations are called "rigid transformations" because they do not change the size or shape of the figure. The image is always congruent to the original.
On the other hand, dilations change the size of the figure, so the image is <em>not congruent</em> with the original.
Rigid transformations result in congruent figures.
