60 seconds = 1 minute
135 seconds = 135/60 = 2.25 minutes
Answer: Choice D
- k < 5
- Graph has an open hole at 5 and shading to the left
============================================================
Explanation:
We solve this as if it were an equation. In other words, we follow the same sort of steps.
To solve k - 3 = 2, we add 3 to both sides getting k = 5
So solving k - 3 < 2 leads to k < 5. The inequality sign does not flip.
To graph k < 5, we will plot an open hole at 5 and shade to the left
The open hole means we do not include 5 as part of the solution set. The graph visually represents all values smaller than 5.
This all leads to choice D being the final answer.
Answer:
Step-by-step explanation:
Let the width be X ft
Length = 2x - 40
Total area = 33,600 sq.ft
length * width = 33,600
(2x - 40) * x = 33,600
2x² - 40x -33600 = 0
