If: 4x = 5y Then: x = 5y/4
I think that wants to be 16x2 - 40xy + 25y2 That factors to (4x - 5y)(4x - 5y) or (4x - 5y)2
If you mean: 4x-5y = -12 and -x+5y =18 Then the solutions of the equations are: x = 2 and y = 4
Assuming 4x = 5y Then x/y = 5/4
-5y-35 = -4x -5y = -4x+35 y = 4/5x-7 The y intercept is -7
- X + 5Y - 4X + 7 gather terms - X - 4X ( same as - X + (- 4X ) 5Y 7 = - 5X + 5Y + 7 ----------------
4x-5y+20 = 0 -5y = -4x-20 y = 4/5x+4 which is now in slope intercept form
4x-5y = 13 -5y = -4x+13 y = 4/5x-13/5 Slope = 4/5 or 0.8
4x + 5y = -8 is an equation with two variables. While you can solve for y = something, you won't come up with a single number. For example, 4x + 5y = -8 5y = -4x - 8 y = -4x/5 - 8/5. And you can do the same for x = something in terms of y.
It is: 7x+10y
no, 4x-3y=11x 3x-5y doesn't equal -11
solv by cramr's rule [ 2x - 5y ] = 2 , [-4x + 10y ] = 1
If the equation is -20x-5y=40 then the answer is -5y=20x+40 which equals y=-4x-8 If the equation is -20x+5y=40 then the answer is 5y=20x+40 which equals y=4x+8
4x - 5y = -2 so 5y = 4x + 2 or y = 4/5x + 2/5 Now that it is in the standard form, the slope is the coefficint of x ie 4/5.
4x+5y = 30 5y = -4x+30 y = -4/5x+6 in slope intercept form So the y intercept is 6.
The standard form, which is the form that can be generalised to 3 or more dimensional spaces, is 4x + 5y - 13 = 0
If you mean: 4x+5y=-20 then the y intercept is (0, -4) and x intercept is (-5, 0)
y = (11-4x)/5
If you mean: 4x+5y = 40 then y = -0.8x+8 whereas as -0.8 is the slope and 8 is the y intercept of a straight line equation
I understand this to be 4x + 3y - 5x + 2y. -x + 5y
Let's see. 4X - 5Y = - 20 - 5Y = - 4X - 20 Y = 4/5X + 20 slope(m) = 4/5 Is positive
4x+5y = 20 5y = -4x+20 y = -4/5x+4 So the slope is -4/5 or as -0.8 and the y intercept is 4
