Answer:
E
Step-by-step explanation:
5 is to ST as ST is to (5+7)
5/ST = ST/12 (ST)^2 = 60 ST = sqrt (60) = 2 sqrt 15
<span>A direct variation is of the form
y = kx
where k is the constant of variation
In most cases k is positive in which case
y increase in direct proportion to an increase in x
Example
k = 2
x = 1, y = kx = 2(1)= 2
x = 3, y = kx = 2(3) = 6
Occasionally k is negative in which case
y decreases in direct proportion to an increase in x
Example
k = -2
x = 1, y = kx = (-2)(1) = -2
x = 3, y = kx = (-2)(3) = -6
---------------------------
This is not to be confused with an indirect variation which is of the form
y = k/x
where k is the constant of variation
Example
When k is positive y decreases inversely as x increases
k = 2
x = 1, y = k/x = 2/1 = 2
x = 3, y = k/x = 2/3 = 2/3
When k is negative y increases inversely as x increases
k = -2
x = 1, y = k/x = -2/1 = -2
x = 3 y = k/x = -2/3 = -2/3</span>
Answer:
I believe it is B
Step-by-step explanation:
As you see however they sell you have to add up the profits of them so it would be B.
