Answer 2

The private school function: f(t) = 18*t + 85

The public school function: g(t) = 15*t + 95

Do you agree @Sparklestaraa

Answer 3

If so, do you remember how to use the online graphing program Desmos?

Answer 4

If so, go there and graph y = 18*t + 85 and then y = 15*t + 95 on the same graph.

Answer 5

Yes i agree :) I remember

Answer 6

Go there and graph the two lines. Desmos.com

Get the point of intersection of the two graphs by clicking the mouse foot on the point of intersection. Then, come back and post what the coordinates are or post the graph.

Then, we will go to part C and get a wrap.

Answer 7

Wow, the lines are close. Were you able to see the point of intersection? Just a second.

Answer 8

kk :)

Answer 9

it looked like it had a dot already outlined so i pressed that dot :)

Answer 10

What were the coordinates that popped up and you pressed the mouse foot on the dot.

Answer 11

Oh, I see it.

(3.33, 145)

Answer 12

(10/3, 145)

Answer 13

yes :)

Answer 14

whats 10/3, 145?

Answer 15

Those are the exact coordinates of the point of intersection. 10/3 = 3.33 approx

Answer 16

So, in 3.33 years (3 years and 4 months) after the two schools open in 2005, the two schools will have the same number of students.

Answer 17

Four months into the school year beginning in 2008, the two schools will both have an enrollment of 145 students.

Do you think that is what the point of intersection means?
