Answer: y=3
Step-by-step explanation:
the initial statement is
y
∝
1
x
to convert to an equation multiply by k the constant
of variation
⇒
y
=
k
×
1
x
=
k
x
to find k use the given condition
y
=
15
when
x
=
5
y=kx⇒k=y x=15×5=75
equation is

∣22y=75x22∣∣
when x=25 then
y=75 25=3
Answer:
The answer is D
Step-by-step explanation:
A cant be right because the graph isn't a straight line.
B cant be right because from 0 to 60 the graph the line goes at a(n) upward slope not a straight line.
Although the first part of question c is right, the second part is wrong. From 50-90 the ling goes at a downward slope via decreasing, which isn't equal like it said so question C is wrong.
So the correct answer is D
A hypothesis is only tentative: to make sure it's valid, you have to test it.
