Factor 25x squared minus 4y squared?
(5x - 2y)(5x + 2y)
What is the equation of the xy-trace for the plane 5x 2y 3z equals 10?
5x 2y = 10
5x plus 2y equals 19 x - 2y equals -1?
(3, 2)
What is the slope of 5x-2y equals 11?
5x-2y=11 -2y=-5x+11 y=(5/2)x - 11/2 Slope is 5/2
5x-2y equals -3 what is the slope?
5x-2y=-3 -2y=-5x-3 y=(5/2)x+3/2 slope is 5/2
What is 5x-2y equals 10 in slope intercept form?
5x - 2y = 10 2y = 5x - 10 y = 2.5x - 5......which is the equation in slope intercept form.
What are the exact values of x and y when 3x plus 2y equals 5x plus 2y equals 7?
If: 3x+2y = 5x+2y = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtract the 1st equation from the 2nd equation: 2x = 0 or x = o By substitution: x = 0 and y = 3.5
5x plus 3y equals 17 5x - 2y equals -3?
Multiply the bottom equation by -1
What are the solutions to the simultaneous equation of 3x plus 2y equals 5x plus 2y equals 14 showing work?
If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7
3x plus 2y equals 20 and 5x-2y equals 1?
3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
What is 5x - 2y equals 20?
5x - 2y = 20Solve for x:5x = 2y + 20x = 2/5y + 4Solve for y:-2y = -5x + 20y = 5/2x - 10Neither equation can be simplified further without one of the variables already being known.
What are the values of x and y in the equation 3x plus 2y equals 5x plus 2y equals 7 show work?
If: 3x+2y = 5x+2y = 7 which is the same as 7 = 7 = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtracting equations: x = 0 Therefore by substitution: x = 0 and y = 3.5
