If X varies inversely as y2 and x equals 5 when y equals 12 Find x when y equals 6?
80
X varies directly with y and z x equals 400 when y equals 8 and z equals 10 Find x when y equals 10 and z equals 12?
x = 5.y.z so 5.10.12 = 600
What is the x and y intercept of 2x plus 3y equals -12?
To find the y-intercept, plug 0 in for x: 3y = -12 y = -4To find the x-intercept, plug 0 in for y: 2x = -12 x = -6The y-intercept is y = -4, and the x-intercept is x = -6.
Find an equation of variation where y varies directly as x and y equals 15 when x equals 5 find y when x equals 19?

If y equals 5 when x equals 4 what is the value of y when x equals 12?
13 ? 15
If y varies inversely as x and y equals 24 when x equals 8 find y when x is 4?
y is 12
Assume that y varies inversely as x. If y equals -6 when x equals-2 find y when x equals 5?
-6/y=5/-2 5y=12 y=12/5
If X varies inversely as y2 and x equals 5 when y equals 12 Find x when y equals 6?

If y varies directly as x and y equals fifteend and when x equals three find y when x equals twelve?
y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.
If y equals one-forth x and x equals -12 then what is y?
x equals -12 and y equals 1/4 of -12, so y = -3.
If y varies directly with x find the constant of variation if x equals 8 and y equals 12?
y = cx when x = 8, y = 12 so that 12 = 8c which gives c = 12/8 = 1.5
X varies directly with y and inversely with z x equals 0.12 when y equals 12 and z equals 2 Find x when y equals 1200 and z equals 1?
x = 24
X varies directly with y and z x equals 400 when y equals 8 and z equals 10 Find x when y equals 10 and z equals 12?
x = 5.y.z so 5.10.12 = 600
If y is directly proportional to x and y equals 12. What is the value of x when y equals 5?
Insufficient information. What is x when y = 12?
If y varies directly with x and y equals 6 and x equals -3 find y when x equals 4?
y/x is a constant; so first of you can solve for this constant. y/x=6/-3, or y/x=-2 y/4=-2 y=-8
What is the x and y intercept of 2x plus 3y equals -12?
To find the y-intercept, plug 0 in for x: 3y = -12 y = -4To find the x-intercept, plug 0 in for y: 2x = -12 x = -6The y-intercept is y = -4, and the x-intercept is x = -6.
If x and y are inversely proportional and x equals 13 when y equals 12 w is x when y equals 24?
26.
