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 2x-3y equals 12?
x=12 y=4
What are the x and y intercepts of the problem 3x plus y equals 12?
3x + y = 12The x intercept occurs when y = 0. Then, 3x + 0 = 12 : 3x = 12 : x = 4The y intercept occurs when x = 0. Then, (3 x 0) + y = 12 : y = 12.
Sqrt x-7-5 equals 0?
x = 12
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 x and y are inversely proportional and x equals 13 when y equals 12 w is x when y equals 24?
26.
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.
Evaluate the following expression if x equals 12 y equals 8 and z equals 6?
x=y-8 z=x+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
What is the value of x plus y when x equals 4 and y equals 12?
x+ySince x=4, we can replace the x with a 4:4+ySince y=12, we can replace the y with a 124+12 = 16
If y varies inversely as x and y equals 24 when x equals 8 find y when x is 4?
y is 12
If y equals 5 when x equals 4 what is the value of y when x equals 12?
13 ? 15
What is the answer to 12 x plus 16 y equals when x equals 1 and y equals 2?
You plug in the values of x and y and solve 12x + 16y = ? 12(1) + 16(2) = 12 + 32 = 44
If X varies inversely as y2 and x equals 5 when y equals 12 Find x when y equals 6?
80
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
