Answer:
this is only one functions, it means all is correct.
Answer:
the given equation is y=4/7x
reciprocating both sides you get y/x =7/4
now x and y are directly porportional to each other so
x=ky where k is the constant
or x/y=k ......................(2)
equating 1 and 2
k=7/4
Step-by-step explanation:
Yes, because if you divide 4 and 3 by 2, you get 2 and 1.5
Answer:
x=5/2 or x=2.5
Step-by-step explanation:
x time 2 + 4x=15
6x=15
2x=15
2x=5
Answer:
No mode
