Answer:
A. 2.3 sec and 5 sec
Step-by-step explanation:
We are given that start from 110 feet away, a person on a bicycle rides towards a checkpoint and then it passes it. the rider is traveling at a constant rate of 30 feet per second.
The distance between the bicycle and the checkpoint is given by the equation :

Now we are required to calculate at what times is the bike 40 feet away from the checkpoint. So, substitute d = 40 in the equation

and 
and 
and 
and 
and 
Hence at 2.3 sec and 5 sec the bike is 40 feet away from the checkpoint.
Answer:
6m+24
Step-by-step explanation:
basically you multiply m and 4 by six soooo
6 times m is 6x
6 times 4 is 24
soo
6m+24 is correct
can i have rainliest pleaseee:)b
Y/x=k
when y=9, then x= -3
9/-3=-3
⇒ k= -3
Well, the y-intercept is represented by B. So b would be the dot crossing the y-axis in each graph (which you already circled). Next, the slope for top left is: -1.5, top right is: -1.7, bottom left is: 3, and bottom right is: 1.33. I got those by using this very helpful website named Desmos. Now, I’m order to write the equation for each graph is very simple, all you have to do is put in the slope and y-intercept into the equation. For example, the top left one would be:
y = -1.5x + 4 since we know that the slope is equal to -1.5 and the y-intercept is equal to 4. Hope this helps :)
