Answer:
Step-by-step explanation:
Given the expression
Cancel the common factor: x+y
Thus,
Week 1 : 1 customer tells 3 friends
Week 2: 3 new customers tell 9 friends
Week 3: 9 new customers tell 27 friends
If w represents number of weeks, then (C) represents the model appropriately. Let's see how:
Putting w = 1 , 2 and 3 in each of the options
(A) 3w: 3 for week 1, 6 for week 2, 9 for week 3 ⇒ INCORRECT
(B) w^3: 1 for week 1, 8 for week 2, 27 for week 3 ⇒ INCORRECT
(C) 3^w: 3 for week 1, 9 for week 2, 27 for week 3 ⇒ CORRECT
(D) 3w^3: 3 for week 1, 24 for week 2, 81 for week 3 ⇒ INCORRECT
Hence, the answer is (C)
Answer: The answer is the first bubble
Step-by-step explanation:
1. When you identify the pairs you get: { ( -5,-4), (-1,5), ( -5,3) , (7,8) }
2. When figuring out whether or not it is a function, you have to see if there are any same y values. If there is no y values that are the same, then the relation is a function.
3. This relation is a function.
* Also, if you have a relation that has the two or more of the same x values, the relation is still a function no matter what.
51.245 and 37.15
since they are both the highest
2(a+3)+3(2a-1)
=2a+6+6a-3
=8a+3
