Is 3x-4y plus 5 equals 0 and 6x-8y-1 equals 0 are parallel?
Yes because the slope or gradient are the same 4/3
What would x and y be if the equation is 3x-4y equals 10 and -3x equals 4y equals 8?
3x - 4y = 10-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 100x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3
Are y equals -3x plus 2 and y plus 3x equals 4 parallel?
Their graphs are.
3x plus 2y equals 4 -3x plus 4y equals -10?
(2, -1)
3x plus 56 equals 2x plus 4?
3x+56 = 2x+4 3x-2x = 4-56 x = -52
