Answer:
4+
x = 3
Step-by-step explanation:
4 +
x = 3 (subtract 4 from both sides)
x = -1 (multiply both sides by 2)
x = -2
Answer:
1. Yes 2. No 3. Yes 4. No
Step-by-step explanation: 1 is a function because none of the x values repeat, 2 isn't a function because in the x coordinates, -2 repeats, 3 is a function because if you were to draw a (vertical) line through each point, none of them have two points on one line, 4 is a function because none of the x coordinates point to more than one y coordinate
Given :
Apa-bear weighs 250 lb.
Mama-bear weighs 50 pounds less than Papa-bear does.
Their 2 cubs weigh 80 pounds each.
To Find :
The total weight of the Bear family .
Solution :
Weight of mama bear =
.
Total weight is the sum of all all weight .


Therefore , total weight of the Bear family is 610 lb .
Hence , this is the required solution .

So y=2x is the only answer that fit y=kx, while k=2
