Question

Is the point (7.5, 85) a solution to the inequality you wrote in previous problem? Hint: The variables in the ordered pair are (t, d). (The last question: d<=11.523t)

Answer 1

I think it is true but I wanted to be sure.

Answer 2

okay, plug in the ordered pair into the equation.

Answer 3

the ordered pair is (7.5, 85), which tells us t = 7.5 and d = 85

Answer 4

the equation is d<=11.523t

Answer 5

If I plug in d, I get 85<=11.523t

Answer 6

Now, you plug in t and see if the equation is true.

Answer 7

It is 85 <= 86.4 That's what I got before but I wanted to be sure.
