If y equals 3x and 3x equals 12 then what does y equals?
y = 3x = 12y = 12
How do you solve for y 3x-y equals 12?
-9
3x minus y equals 9 solve for y?
3x-y=9 y=3x-9
Solve by substitution method y equals -4x - 7 y equals 3x?
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
3x - 7y equals 36 and y equals 3x?
1) y - 7y = 36 -6y = 36 y = -6 We know that, y = 3x -6 = 3x x= -2 Conclusion, y= -6, x = -2
What is parallel to y equals 3x 14?
17
How do you write the slope intercept form of the equation 3x-2y equals 14?
y=2/3x-7
Are 3x-y equals 4 and y equals 3x-4 equivalent to each other?
3x - y = 4 Get y by itself to see if it is the same as y = 3x - 4: 3x = 4 + y 3x - 4 = y Therefore, 3x - y = 4 is the equivalent of y = 3x - 4.
If y equals 3x and 3x equals 12 then what does y equals?
y = 3x = 12y = 12
If y equals 3x and 3x equals 15 then what number does y equal?
y = 15 (by transitivity)
How do you rewrite the equation so that y is a function of x 3x plus 3y equals 14 minus 4x?
3x + 3y = 14 - 4xSubtract 3x from each side:3y = 14 - 7xDivide each side by 3:y = (14 - 7x) / 3
How do you solve for y 3x-y equals 12?
-9
Solve 3X plus 7Y equals 14 for Y?
3x + 7y = 14Subtract 3x from each side:7y = -3x + 14Divide each side by 7:y = -3/7 x + 2
3x minus y equals 9 solve for y?
3x-y=9 y=3x-9
What is the answer to 4x-y equals 1 and 3x plus y equals 13?
4x - y = 1 3x + y = 13 Add the equations: 7x = 14 so that x = 2 and then, by the first equations, 4*2 - y= 1 so that y = 7
What is the answer to y equals 3x 3x plus 4y equals 30?
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
Are y equals -3x plus 2 and y plus 3x equals 4 parallel?
Their graphs are.
