so = -4y < -20 making y < 5
8x plus 4y equals 5 is 8x + 4y = 5.
5x+4y = -3 4y = -5x-3 y = -5/4 x - 3 Slope is -5/4.
5x+4y = 20 4y = -5x+20 y = -5/4x+5 Therefore: slope is -5/4 and intercept is 5
The given expression has no solution because without an equality sign it is not an equation.
2x + 6y = 93x - 12y = 15Chose the second equation because you can simplify it.3x - 12y = 15 divide by 3 to both sidesx - 4y = 5 add 4y to both sidesx = 4y + 5Replace 4y + 5 for x to the first equation.2x + 6y = 92(4y + 5) + 6y = 98y + 10 + 6y = 914y = -1y = -1/14x = 4y + 5x = 4(-1/14) + 5x = -2/7 + 5x = -2/7 + 35/7x = 33/7
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
The parallel equation works out as: 4y = 3x+1 which can be expressed in the form of 3x-4y+1 = 0
4(x + y - 5) = 0
x = 5, y = -1
The equation does not have a solution.
11-4y=-5 -4y=-16 y=4
This is a system of two linear equations: x+2y=11 3x-4y=-17 One way to solve this system is to solve for x (or y) in the first equation and then plug it into the second equation to solve for the other variable, which then allows us to solve for our original variable. (1) Take the first equation and solve for x: x=11-2y (2) Plug this value into the second equation: 3x-4y=3(11-2y)-4y=33-10y=-17. We see that y=5. (3) We now plug this into either equation to solve for x: From (1): x=11-2y=11-2(5)=1 We get x=1 and y=5. It's also always a good idea to plug the numbers we found into our original two equations to verify they work. Indeed, x+2y=1+2(5)=1+10=11, and 3x-4y=3(1)-4(5)=3-20=-17.
Yes it is a function. 5x + 4y = 0 the same as: 5x = -4y You can also solve for either variable. x = - ( 4 / 5 ) y y = - ( 5 / 4 ) x
== == y = -x + 5
I assume you are solving for y. First you need to form an equation since you don't have an equal sign. The equation would be 9y - 818 - 4y = 0. Next, you have to isolate the unkown number from the known number by adding 818 to both sides of the equation and you would have 9y - 818 - 4y + 818 = 0 + 818, then your equation would read 9y - 4y = 818. Simplify the unknown number by subtracting 4y from 9y which now makes the equation 5y = 818. To find the value of y, divide both sides of the equation by 5. Hence 5y/5 = 818/5. Thus, y = 163.6. To prove the solution, substitute 163.6 for y and solve.
I don't know whether it's y^2-3y+2+3y-4y-5 or 2y-3y+2+3y-4y-5, so I'll do both.y^2-3y+2+3y-4y-5y^2+(-3y+3y-4y)+(2-5); group them togethery^2+(-4y)+(-3)y2-4y-3OR2y-3y+2+3y-4y-5(2y-3y+3y-4y)+(2-5); group them together(-2y)+(-3)-2y-3
x = 4y - 2x = 6y + 84y - 2 = 6y + 8Subtract 4y from each side:-2 = 2y + 8Subtract 8 from each side:-10 = 2yDivide each side by 2:-5 = yx = 4y - 2x = -22
The answer to the equation 9 plus 5 times 0 equals 45. This was taught in 5 grade math.
Centre of circle: (2, 1.25) Slope of line: 9/4 Equation of line: y-1.25 = 9/4(x-2) => 4y-5 = 9x-18 => 4y = 9x-13
Y=0.5 and X=1
