This is a linear function. Let diameter (inches) be x, circumference (inches) be y, observe that the value of y/x is always 3.14. For example, 15.7/5=31.4/10=...=3.14. Therefore, this is not only a function (one to one correspondence from x to y), it's also a linear function that can be represented as y=3.14x.
Answer:
C.y=-3x-3
Step-by-step explanation:
#1 is 4 for the 1st quartile
The answer to this is .64.
X=21 and the mesure of one would be 120 to check if its correct multiply 5 by 21 then add it to 15 and that would be the answer for what 1 is you can also check of its 21 by multiplying 3 by 21 and subtracting 3 then adding both to get 180 which is the normal measurements of the line. hope this helps somehow
