Answer:
No, she will have 140 cards in 4 months
Step-by-step explanation:
the equations is:
f(x) = 100 + 10x
now x = 4
f(4) = 100 + 10(4)
f(4) = 100 + 40
f(4) = 140
140 does not = 60
The rate of change is +2
as an ordered pair it would be (1,-3),(2,-1)(3,1),(4,3)
For example, think about 8.4 - 2.9.
You have to regroup because you can't subract 4 - 9.
4 turns into a 14 since you borrow from the left number, 8.
8 turns into a 7 after that.
Now, you have to subtract 14 - 9 and 7 - 2. You're answer is 5.5.
You can check your work by doing inverse opperations:
By adding:
5.5 + 2.9 = 8.4
Or by subracting 8.4 - 5.5 = 2.9
Hope this helped you! If you need a better explaination or another example, I will be happy to help you! :)
lets draw a picture of our hexagon:
then, we can rotate 60 degrees counterclockwise (or clockwise) and get the same hexagon. So, the answer is 60 degrees
