-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
How do you solve 20x plus 5y equals 15?
If: 20x+5y = 15 Then: y = -4x+3
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.
4x plus 5y plus z equals 2?
z = -4 x-5 y+2
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
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 ----------------
What is the answer to 4x plus 5y plus 3x plus 5y?
It is: 7x+10y
4x plus 5y equals 51 4x - 5y equals 21?
(9,3)
-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
What are the x- and y-intercepts of the line with equation 4x plus 5y equals 40?
First, put the equation in slope-intervcept form y=mx + b 5y=4x + 40 The y intercept is where x=0 so- 5y= 4(0) +40 solve for y y intercept = (0,8) For the x intercept, y=0 0=4x+40 -4x=40 x= -10 xintercept =( -10.0)
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 -9-2x plus 5y plus 4x plus 3?
It is an expression that can be simplified to 5y+2x-6
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
How do you solve 20x plus 5y equals 15?
If: 20x+5y = 15 Then: y = -4x+3
What is 6x plus 3y-2x plus 5y?
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
Solve by the substitution method 4x-5y equals -8 4x plus 40 equals y?
4x-5y = -8 4x+40 = y => y = 4x+40 Substitute the value of y into the top equation: 4x-5(4x+40) = -8 4x-20x-200 = -8 4x-20x = 200-8 -16x = 192 Divide both sides by -16 to find the value of x: x = -12 Substitute the value of x into the original equations to find the value of y: Therefore: x = -12 and y = -8
What is 6x plus 3y-2x-5y?
4x-2y
