Answer:
-1
Step-by-step explanation:
A function is represented by the following symbol f(x) where f(x) further represents y like this ,

so in this question they are asking what is f(5) which means when the value of x is 5 what is the value of y?
We can see in the graph when x = 5 the value of y is -1 to be exact so
f(5) = -1
or

direct proportion y=kx , k is constant and k does not equal to 0.
17.5=k(21)
k=5/6
when x =39
y=5/6 ×39
y=32.5
What is the series you are referring too?
Answer:

Step-by-step explanation:
We are given that a student needs to make a square cardboard piece.
Perimeter of cardboard should be equal to atleast 92 inches
We have to find that which shows reasonable domain for f(s)
Let s be the side of square cardboard
We know that perimeter of square =f(s=)
Then, perimeter of cardboard=

Dividing by 4 on both sides

Hence, the domain of function
Therefore, option d is true.
Answer:d: 
Answer:
1. -2w-1 cuz when in parethese it all become negative. 2. factors of 32 is 1,2,4,8,16,32. and factors of 24 is 1,2,3,4,6,8,12,24. and the way you should write 32k+24 is 4(8k+6)
