So, 27=30 and 18=20 rounded
so what you would do now is multiply 30 x 20 and you get $600
A- When one variable increases the other variable decreases. :)
Answer:
tangent: y-
= -4(x -
)
Step-by-step explanation:
differentiating

isolating y' to one side and simplifying


when x =
,
y' = 
y' = 
tangent: y-
= -4(x -
)
This is a reduction because the scale factor is in between 0 and 1.
