Answer:
20
Step-by-step explanation:
In 12 years, the sum of their ages will be 24 more than it is now. The sum of their ages now is 61-24 = 37.
If Jennifer is 3 years older than Peter, we have ...
j + (j -3) = 37
2j = 40 . . . . . . add 3
j = 20 . . . . . . . divide by 2
Jennifer is now 20 years old.
_____
Peter is now 17 years old. In 12 years, they will be 29 and 32, so their ages will sum to 61.
Answer: D. No; the graph fails the vertical line test.
The vertical line test is a tool used to determine if we have a function. If we can draw a single straight vertical line through more than one point on the red curve, then the graph is said to have failed the vertical line test. Consequently, this leads to the relation not being a function.
For this circle graph, we can draw a vertical line through more than one point, which is why we don't have a function here.
Put another way, there are inputs (x) that produce more than one output (y), so that's why we don't have a function.
