Answer:
Step-by-step explanation:
Yes its B C=8k+24
<span>4y-9=15
Add 9 to both sides.
4y = 24
Divide both sides by 4.
y = 6
The value of y is 6.</span>
Answer:
Step-by-step explanation:
The quadratic formula of a quadratic equation
We have the equation:
Substitute:
Volume of a cylinder is pi*r^2*h where r = radius and h = height
so 3^2*6*pi = 9*6*pi = 54pi
54 pi is the answer. mark me brainliest please!
<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>
