Answer:
x= 1/31
Step-by-step explanation:
it mental math
I think the answer is 9-25x
21/3 is 7 so there are 7 pens for every 1 ratio
7 x 1 = 7
21+7 = 28
find the gradient = change in y/change in X
-5 - -3/-3 - -6
= -2/3
take any two point say -3,-5 and equate to the gradient
Y - 5 /X - 3 = -2/3
cross multiply
3y - 15 = -2x + 6
3y = -2x +6 + 15
3y = -2x + 21
y = -2/3x +7
Answer:
This is the graph of a <u>parabolic</u> function.
- Without seeing the dropdown menu, I assume that is what the question is asking. It's parabolic: the shape is like an upside-down u or an upside-down v.
Michael Jordan's hang time is <u>.9</u> seconds.
- The parabola starts at 0 seconds, and ends at t = .9 seconds.
The maximum height is about <u>1</u> meter.
- The vertex or very top of the parabola is at h = 1.
For t between t = .5 and t = 1, the height is <u>decreasing/falling/going down.</u>
- I can't tell this one for sure unless I can see the dropdowns. But I can say that from .5 to 1, whatever it is, it's dropping or falling, because the height is getting less and less.
