Answer:
B
Step-by-step explanation:
They are increasing by 1 vertically. Hope this helps!! :)
So.. hmm check the picture below
now, to know where A and B are, that occurs when the parabolic equation equates the linear one
thus

now, running that on the quadratic formula, you end up with the values of 3.00402497440839842242 and 0.77175977895483027713
thus B rounded up is 3.004 and A rounded up is 0.7718
what's the "y" value for B?, well, you can use either the linear or quadratic equation for that, let's use the quadratic one
In order to begin figuring that out, we need to know how both of their plans work.
3: terms/ 12, 8r, -3, s, -5, 15t coefficients/ 8r, 1s, 15t
Answer:

To find this you must find the slope first:

which is, after performing some calculating is -2.
Next you need to set up your eqaution:

when you set it up, and substitute the variables for your slope and points you should get this:


add 2 to both sides

subtract y from both sides
