8x = 2x + 15 6x = 15 x = 15/6 = 2.5
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
x2-2x-15 = (x+3)(x-5) when factored
-3(x-5)=2x -3x+15=2x 15=5x x=3
8
The answer depends on the sign preceding the value 15 (which is not given in the question). If y = -2x+15 then (0,15) if y= -2x-15 then (0,-15)
2x - 7 = 15 2x = 22 x = 11
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
2x - 5 = 15 2x = 20 x = 10
No they are parallel.
4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11
x2 + 2x - 15 = (x - 3)(x + 5)
That line is [ y = 2 cos(2x) ].
2x-17=13 2x=30 x=15
It is: y = -1/2x-8
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
