Let's look at each one of the intervals.
Interval A
Interval A looks like she's going at a pretty steady pace, so Interval A is not the correct answer.
Interval B
Interval B looks like she stays at 2.5 for an hour. That looks like a traffic jam to me!
The correct answer is Interval B.
Hope this helps! If it does, be sure to rate, thank and if it really helped, give brainliest. It helps me rank up. Thanks! :)
A rational number would be 81/10 or 8.1
First, subtract 7 on both sides. Now, you have 4x<1. Divide by 4 on both sides. Finally, you get x<1/4 (a quarter or said as one-fourth). So, x<1/4.
Answer:
9x/4 + 30 + 5x/4
Step-by-step explanation:
This is infinity solutions -
33x-33+99=33x-33-99
99=-99
Since 99 __equal -99 the equation has many solutions
