X plus y equal to -1 and 4x minus 3y equal to 12 what is the answer?
x + y = -1 (a) 4x - 3y = 12 (b) 3(a)+(b) gives 3x + 3y + 4x - 3y = -3 + 12 or 7x = 9 or x = 9/7 then x + y = -1 gives y = -1 -x = -1 - 9/7 = -16/7 So, x = 9/7 and y = -16/7
What is the answer to the equation 12-3y equals 15?
12-3y = 15 -3y = 15-12 -3y = 3 y = -1
What is 4x plus 3y equals 12 in slope intercept form?
4x+3y = 12 3y = -4x+12 y = -4/3x+4
Graph -8x plus 3Y equals 12?
-8x+3y=12 3y = 8x+12 y = (8/3)x + 4 So it will be a line with slope 8/3 and y intercept of 4
What is 3y squared - 3y over y - 1?
(3y2 - 3y)/(y - 1) = 3y(y - 1)/(y - 1) = 3y
