y = -5x + 9 is the equation of a straight line. It cannot be parallel or perpendicular by itself, you need another line to compare it to.

0In the absence of equality signs it's difficult to say but in general if the slope remains the same and the y intercept differs then they are parallel

When two lines are parallel, they have the same slope. For example:y=5x-3 andy=5x+9These lines are parallel, because they have the same slope.When two lines are perpendicular they have negative reciprocal slopes. For example:y=2x-6 andy=-1/2x+2These lines are parallel, because they have negative or opposite reciprocal slopes.

It will be any of the equations that has the same slope of y = 5x+9 but with a different y intercept

The equations will have the same slope as y = 5x+9 but a different y intercept

To answer this question we need to first get the slope of the line 5x-4y=9 by rearranging it in the form of y=mx+b: 5x-4y=9 4y=5x-9 y=(5/4)x-9/4 Since the slope of parallel lines are negative reciprocals of each other, the negative reciprocal of 5/4 is -4/5, therefore the slope of a line parallel to the line 5x-4y=9 is -4/5

5x = 4x + 9 x = 9

If X = 9 then 5X would = 5 x 9, which is 45.

39 = 5x + 9 5x = 39 - 9 5x = 30 x = 30 / 5 x = 6

5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3

-7+11x = 9-5x 11x+5x = 9+7 16x = 16 x = 1

For example 5x \ 9 x 5 + 10 + 72 = 9 So you move 72 over to 9 and minus it 5x / 9 x 5 + 10 = 9-72 Then bring 10 over 5x / 9 x 5 = -63- 10 Then brong 5 over 5x / 9 equals - 73 5x equals -73 times 9 5x equals 146 X equals to 146 divide by 5 Thanks you Hello Israel

5X + 9 5(3) + 9 15 + 9 = 24 ====

5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8

It is 3x + 5y = 155 The slope of the line 5x -3y = 9: 5x - 3y = 9 → 3y = 5x - 9 → y = 5/3 x - 3 → slope is 5/3 → slope of perpendicular line is -3/5 Intercept at x = 15 → y = 5/3 x 15 - 3 = 22 → equation of perpendicular line is: y - 22 = -3/5 (x - 15) → 5y - 110 = -3x + 45 → 3x + 5y = 155

5x - 9 = 4x 5x - 4x - 9 = 4x - 4x x - 9 = 0 x - 9 + 9 = 0 + 9 x = 9

6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1

-27 = 3x-9 = x

The answer is -8.

Let, f (x) = - 5x - 9 Therefore, f(x) + 7 = - 5x - 9 + 7 f(x) + 7 = - 5x - 2

if you meant 5x+9=3*15 then, 5x = 36, x = 7.2 if you meant 5x+9=3x+15 then, 2x = 6, x = 3

5x + 9 = 4Subtract 9 from each side:5x = -5Divide each side by 5:x = -1

By definition, a parallelogram two separate pairs has parallel sides. The only type of parallelogram that has perpendicular sides is a rectangle. All others have non-perpendicular sides.
