4x+5y = 7 5y = -4x+7 y = -4/5x+7/5 in slope intercept form So the slope of the perpendicular line is plus 5/4
548
yes it is!
5x + 3y = 17 is in its simplest form because there are no alike terms to combine.
3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
5x = 4x + 9 x = 9
33
5x - 4x = 13 - 3 ie x = 10
4x - 10 + 5x = 719x = 81x = 9
5x+12 = 4x-88 x = -100
5x+3y
5x+1
5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
5x + 3 = 4xSubtract 3 from each side:5x = 4x - 3Subtract 4x from each side:x = -3
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
