Answer:
25
Step-by-step explanation:
5+5+5+5+5=25
If the x's repeat, then it is NOT a function.
For problem 2:
(3,5) and (6,5) actually don't cause a problem for us. Repeating y's in okay! So yes, this relation can be a function.
For problem 3:
(2,5) and (2,9) uh oh! We have x=2 being mapped to two different locations. Bad bad bad. This is NOT a function.
Slip and slide method
x^2-x-12
(x-4)(x+3)
(x-4/3)(x+3/3)
(3x-4)(x+1)
Final answer: D

Answer:
3 3/4 tablespoons of coffee to make 10 cups of coffee
3 3/4 =15/4
10 cups require 15/4 tablespoon of coffee
