What are the x and y intercepts of -2x equals 20 plus 5y?
-2x = 20 + 5y-2x - 20 = 5y-2/5x - 4 = yX Intercept = (-10,0) or -10Y Intercept = (0,-4) or -4
X2 plus 2x-4 equals 0?
x2+2x-4 = 0 x = (-2 plus/minus sqrt (4-(4x1x-4)) / 2 x = (-2 plus/minus sqrt 20)/2 x = (-2 - sqrt 20)/2 or (-2 + sqrt 20)/2 x = -3.236 or 1.236
What is the x in x plus 4 equals 2x plus 3?
1
What are the zeros in the function of 2X squared plus 3X -20 equals zero?
2x^2 + 3x - 20 = 0 is 2x^2 + 8x - 5x -20 = 0 is 2x(x + 4) -5(x + 4) = 0 is (2x - 5)(x +4) = 0 Hence 2x -5 = 0 which gives x = 2.5 or x + 4 = 0 which gives x = -4
What type of lines are these y equals 2x plus 4 and 12 equals 2y plus x?
If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines
What is the answer to 4 plus 2x equals 20?
8
If -2x plus 20 equals 3x what is x?
-2x+20 = 3x 20 = 3x+2x 20 = 5x 4 = x So x = 4
2x plus 4 equals -16?
2x+4 = -16 2x = -16-4 2x = -20 x = -10
What is x in the problem 2x plus 10x - 4 equals 20?
2x + (10x - 4) = 20 2x + 10x - 4 = 20 12x - 4 = 20 12x = 24 x = 2
How do you answer 2x-4 equals 20?
2x-4 = 20 2x = 20+4 2x = 24 x = 12
What are the x and y intercepts of -2x equals 20 plus 5y?
-2x = 20 + 5y-2x - 20 = 5y-2/5x - 4 = yX Intercept = (-10,0) or -10Y Intercept = (0,-4) or -4
If x equals 4 then 2x plus 7 equals?
If x=4 then 2x+7 =
What is the answer to 2x plus 5 plus x2x-1 plus 2x plus 4?
x equals 4
Solve by the method of elimination 2x plus 3y equals 40 3x plus 2y equals 20?
y=16 x= -4
3x plus 8 equals 2x plus 12 what is x?
add; 5x =20 so x = 4
3x plus 56 equals 2x plus 4?
3x+56 = 2x+4 3x-2x = 4-56 x = -52
What is the value of x in this problem x plus four plus two x equals x plus twenty?
x+4+2x = x+20 x+2x-x = 20-4 3x = 16 x = 5 and 1/3
