-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 this equation using the system of substitution y equals 6x-11 and -2x-3y equals -7?
First of all, you have two equations.Y=6X-11 -2X-3Y=-7What you should do is substitute the Y in equation two with 6X-11. Now Y is gone from equation two. Solve for X. Substitute the value of X into equation one to find the Y value.First, substitute Y in equation two with equation one (excluding the isolated Y):-2X-3Y=-7-2X-3(6X-11)=-7-2X-18X+33=-7-20X+33-33=-7-33-20X=-40-20/-20X=-40/-20X=2Now we would substitute X in equation one with the X value of 2:Y=6X-11Y=6(2)-11Y=12-11Y=1Therefore, X=2 and Y =1.

20
What is 20x plus 80y equals 0 in y equals mx plus b?
20x + 80y = 0Subtract 20x from each side of the equation:80y = -20xDivide each side by 80:y = -1/4 xm = -1/4b = 0
Equation 2x plus 5 equals 25 for x?
2x + 5 = 25 2x = 20x = 10
How do you turn 20x plus 80y equals 0 into slope intercept form?
If: 20x+80y = 0 Then: 80y = -20x And: y = -0.25x So the slope is -0.25 and it has no y intercept
What is the solution for 50x² equals 20x-2 equals 0?
50x squared equals 20x-2 equals zero is not possible, for 20x-2 = 0 --> x = 1/10 While 50x2 = 0 means that x should be zero. So either 50x2 =/ 20x-2 or 20x-2 =/ 0
Y plus x equals 9 10y plus 20x equals 100?
y + x = 9 10y + 20x = 100 This is a basic linear system of equalities. We can start by rewriting the first equation as: -10y - 10x = -90 by multiplying the equation by -10, from here we can eliminate y and solve for x (-10y - 10x = -90) + (10y + 20x = 100) = (10x = 10) This yields x = 1, and by plugging x into the first equation y = 8
What is X in 20x equals 3.65?
If: 20x = 3.65 Then: x = 0.1825
What is the slope of a line perpendicular to the line whose equation is 20x plus 12y equals 2012?
20x+12y = 2012 12y = -20x+2012 y = -5/3x+503/3 Therefore the perpendicular slope is the positive reciprocal -5/3 which is 3/5
What number is used to complete the square for the equation x2 equals 20x?
x2=20x 0 is an obvious solution if x is not 0, then divide both side by x, so x=20 so the solutions are 0 and 20
