If y equals 5 when x equals 4 what is the value of y when x equals 12?
13 ? 15
What is the value of y equals 2x when x equals 4?
y=8 y = 2x y = 2(4) <-- substitute 4 for x y = 8 <-- this is your answer
Y equals 2x plus 10 when x equals 4 what is the value of y?
18
If x equals 3 and y equals 4 what is the value of 2x plus y - 1?
x = 3 y = 4 2x + y - 1 = (6) + (4) - 1 = 9
What is the range of the relation y equals to absolute value of x to 4?
y=|x|/4 The range is [0 , ∞ )
What is the value of the expression x equals 4 and y equals 3?
The value is 1 if (x, y) = (4, 3) and 0 otherwise.
If y equals 5 when x equals 4 what is the value of y when x equals 12?
13 ? 15
What is the value of y equals 2x when x equals 4?
y=8 y = 2x y = 2(4) <-- substitute 4 for x y = 8 <-- this is your answer
What is the value of x when y equals 4 and z equals 1?
x equals 7
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
Y equals 2x plus 10 when x equals 4 what is the value of y?

When x equals 8 and y equals - 4 find the value of 2x - y?
x = 8y = -42x - y = 2(8) - (-4) = 16 + 4 = 20
What is the range of the relation y equals to absolute value of x to 4?
y=|x|/4 The range is [0 , ∞ )
If x equals 3 and y equals 4 what is the value of 2x plus y - 1?
x = 3 y = 4 2x + y - 1 = (6) + (4) - 1 = 9
What happens to the value of y when the value of x changes in y equals 4x?
y = 4x as the value of y changes value of x changes by 4 times :) its simple
X plus y equals 4 2x plus y equals 10?
2x+y = 10 x +y = 4 Subtract bottom equation from top equation: x = 6 Substitute the value of x into the equations to find the value of y: x = 6 and y = -2
Substituiotion method to find the value of y y equals 2x plus 5 x plus y equals 4?
y = 2x+5 x+y = 4 Substitute the value of y into the second equation: x+2x+5 = 4 x+2x = 4-5 3x = -1 Divide both sides by 3 to find the value of x: x = -1/3 Substitute the value of x into the original equations to find the value of y: x = -1/3 and y = 4 and 1/3
