I think you basically just got to add everything up . I mean , i can already tell this is a graph question but it says perimeter so perimeter somehow means add everything up. But im still not too sure ..
you didn't give the options but constant of proportionality is a number you have to multiply x by to get y.
y=kx is the equation that expresses the proportionality of x and y
the constant of proportionality is k, so k=2
y= kx becomes y=2x
so y = 2x should be the answer
Answer:
there is no solution because the 3x cancels itself out leaving 4=0
Step-by-step explanation:
Answer:
A, B, C and F
Step-by-step explanation:
We have according to the options:
A. 
B. 
C. 
D. 
, which is not rational.
E. 
, which is not rational.
F. 
Hence, the expressions representing rational numbers are A, B, C and F.
Okay. Trying to look at it without anything else. F(4) is also saying x=4.
g(x) is another way of saying y= ... So if the question is asking what is x, then 4 is x.
