4x plus 5y equals -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.
Which equation is equivalent to 4x 5y 7?
I can't tell what sign is before 5y, so I'll assume +. 4x+5y=7. Double this is 8x+10y=14, triple is 12x+15y=21. etc
How do you solve 20x plus 5y equals 15?
If: 20x+5y = 15 Then: y = -4x+3
-20x 5y equals 40 changed to slope-intercept form?
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
solv by cramr's rule [ 2x - 5y ] = 2 , [-4x + 10y ] = 1?
solv by cramr's rule [ 2x - 5y ] = 2 , [-4x + 10y ] = 1
What is the value of x if 4x equals 5y?
If: 4x = 5y Then: x = 5y/4
What is negative X plus 5Y subtract 4X plus 7 simplified?
- X + 5Y - 4X + 7 gather terms - X - 4X ( same as - X + (- 4X ) 5Y 7 = - 5X + 5Y + 7 ----------------
4x plus 5y equals 51 4x - 5y equals 21?
(9,3)
What is the y intercept for -5y-35 equals -4x?
-5y-35 = -4x -5y = -4x+35 y = 4/5x-7 The y intercept is -7
What the prime factors of the trinomial 16x -40xy plus 25y?
I think that wants to be 16x2 - 40xy + 25y2 That factors to (4x - 5y)(4x - 5y) or (4x - 5y)2
What is 4x 3y -5x 2y?
I understand this to be 4x + 3y - 5x + 2y. -x + 5y
What is the slope of the line 4x-5y equals 13?
4x-5y = 13 -5y = -4x+13 y = 4/5x-13/5 Slope = 4/5 or 0.8
What is the slop and y-intercept of 4x-5y equals -2?
4X - 5Y = - 2- 5Y = - 4X - 2Y = (4/5)X + 2/5m(slope) = 4/5==================
What is the ratio of x to y 4x 5y?
Assuming 4x = 5y Then x/y = 5/4
How do you solve 4x-5y plus 20 equals 0?
4x-5y+20 = 0 -5y = -4x-20 y = 4/5x+4 which is now in slope intercept form
What are the soluition of these epautions 4x -5y -12 and -x 5y 18?
If you mean: 4x-5y = -12 and -x+5y =18 Then the solutions of the equations are: x = 2 and y = 4
what 4x+5y=?
cube.
