now, if we check what is 36 ÷ 8 = 4.5, so -36/8 = -4.5, and -4.5 = -4.5, so they're both equal, neither is greater.
The first answer is correct, if you go back by 5% each year you will see that.
The score set above has no mode
This is because mode is a measure of what score occurs the most
In this score set no numbers occur more than once
Part A:
Yes this is a function of x. Specifically the function is f(x) = x^2
The inputs (x) are squared to get the outputs (y).
For example,
f(x) = x^2
f(-3) = (-3)^2 <<--- input is x = -3
f(-3) = 9 <<--- output is 9
The pair of values -3 and 9 are shown in the table (column on the very right side)
The fact that each input leads to exactly one output is what makes this a function. If we had an input lead to multiple outputs, then it wouldn't be a function.
=============================================================
Part B
Replace every x with 150 and then use the order of operations PEMDAS to simplify
f(x) = 20+3x
f(x) = 20+3*x
f(150) = 20+3*150 <<--- x has been replaced with 150
f(150) = 20+300
f(150) = 320
So the value of f(150) is 320
The input is 20
The output is 320
x is the number of hours
y or f(x) is the total cost
So this means f(150) = 320 represents the idea that 150 hours of renting the rowboat leads to a total cost of $320
The answers -1/2
-4/5 is -.8 and
10/16 is .625
-.8 times .625 is -.5
and -.5 in fraction is -1/2
