Answer:
k(-1) = 7.
Step-by-step explanation:
k(-1) is the value of the function k when x = -1.
You read this off the graph.
Find the value of the point on the graph which corresponds to x = -1. From x = -1 on the horizontal axis move straight up until you meet the graph of k. Now look horizontally to the right and read off the value on the vertical
y-axis
You'll find it is 7.
We know that π = 180°, therefore:

Answer: correct
Answer:
18
Step-by-step explanation:
Divide 12 by 4 and get 3.
If we add 3 to 12(which would be 15), we would get the total amount of younger cousins.
If you divide 15 by 5 (since there are 5x more), you will get 3.
So... there are 3 older cousins...
Now, there are 15 younger cousins and 3 older cousins.
15 + 3 = 18
Therefore, Jerry has 18 cousins altogether.
