Answer:
6384
Step-by-step explanation:
multiply 48, 16, and 7
y = - 3
Since y varies directly as x then
y = kx ← ( k is the constant of variation )
to find k use y = - 1 when x = 3
k =
=
= - 
hence y = -
x
when x = 9, then
y = -
× 9 = - 3
B is your answer

Answer:
i think 6.44
Step-by-step explanation:
first the diameter is 4.6 then multiply the 4.6 with 1.4 and u obtaine 6.44 (note:iam not sure iam still in seven grade)
The slope is -2/3.
You have to do -2-2 and you get -4.
Then you do 12-6 and you get 6.
The final step is to do -4 divide 6 and you get -2/3.
