If f x varies directly with x2 and f x 96 when x 4 find the value of f 2?
f(2) = 24.
F x varies directly with x and y equals -2 when x equals 8 Find the constant of variation k?
What is y? Fx varies with x, but y could be anything.
X varies directly with y and inversely with z x equals 20 when y equals 8 and z equals 4 Find x when y equals 4 and z equals 8?
The answer is x=10. If: x=20 y=8 z=4 then: y=8/2=4 z=4*2=8 since x varies directly with y, meaning whatever happens to y, happens to x, so if y was divided by 2, then x should be divided by 2. After all, the inverse of division is multiplication.
What is the LCM of 120 and 16?
To find the LCM, you need to find the GCF. 120 factors to [2 2 2 3 5] 16 factors to [2 2 2 2] Common factors [2 2 2] GCF = 8 Now, the LCM is the product divided by the GCF 120 * 16 / 8 = 240 ■
Find a equation of variation where y varies directly as x and y equals 0.8 when x equals 0.4?
direct variation: y = kx y = kx k = y/x = 0.8/0.4 = 2
If y varies directly as x squared find k when x 2 and y 8?
If y varies directly as x and if x = 2 when y = 8 then k = 4.
If f x varies directly with x2 and f x 96 when x 4 find the value of f 2?
f(2) = 24.
Find an equation of variation where y varies directly as x and y equals 8 when x equals 2 find y when x equals 10?

F x varies directly with x and y equals -2 when x equals 8 Find the constant of variation k?
What is y? Fx varies with x, but y could be anything.
What is the constant of variation k if x .5 and y 1 Assume y varies directly as x?
If y varies directly as x then k = 2.
Find an equation of variation where y varies directly as x and y equals 2 when x equals 10 find y when x equals -25?
y = -5
If Y is 5 when x is 2.5 and y varies directly with x find y when x is 10?
y varies directly with x means y = kx, where k is the constant of the variation. When x = 2.5 and y = 5, we have y = kx 5 = 2.5k k = 2 When x = 10, y = kx y = (2)(10) y = 20

X varies directly with y and inversely with z x equals 20 when y equals 8 and z equals 4 Find x when y equals 4 and z equals 8?
The answer is x=10. If: x=20 y=8 z=4 then: y=8/2=4 z=4*2=8 since x varies directly with y, meaning whatever happens to y, happens to x, so if y was divided by 2, then x should be divided by 2. After all, the inverse of division is multiplication.
