If Dinah can skate 1/2 lap in 15 seconds,she can skate 1 lap in 30 seconds. This is because 15 multiplied by 2 is equal to 30.
121 should be the correct answer
To solve this absolute value equation, we can use find the solutions as follows taking into account the definition of absolute value, then, we have:

Now, we can solve both equations to find the solution(s):
First case:

Second case:

Then, both solutions are the same, because of the absolute rule (this is the point when y = 0, that is the x-intercept for this function.)
Therefore, the solution set is {19/20}.
(5, 3) (-6, 3)
The slope is 0 Slope = m = (Y2<span> -Y</span>1<span>) </span>÷<span> (X</span>2<span> -X</span>1<span>) (Y2 -Y1)=0
SO, the distance is just the difference in the x values.
distance = 5 --6 = 11

I am so sorry I would love to help you but I haven't gotten that far in my classes, how long do you have? My sister should be coming home soon and she's learned this before
