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.
Answer:
y = 4
or (0, 4)
Step-by-step explanation:
intersecting the y-axis is basically when x is equal to 0.
1.5(0) +4.5y = 18
y = 4
So your y-intersect is (0, 4) and thats when it intersects the y-axis.
Answer:
B
Step-by-step explanation:
sum means addition so n plus 9 would give you the sum of the both
Answer:
-25
Step-by-step explanation:
Using the commutative property of addition, we can rearrange the expression to 56-56-25. 56-56 = 0, so the answer is 0 - 25 = -25.
I think the ratio is for for every 4 packs it cost 10 dollars so in all it would cost 30 dollars
