What is the slope of the equation 5x plus 4y equals negative 3?
5x+4y = -3 4y = -5x-3 y = -5/4 x - 3 Slope is -5/4.
How do you solve 8x plus 6 equals 3x-4?
8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2
-8x plus 5 - 3x equals -6?
-8x + 5 - 3x = -6Combine the 'x' terms on the left side:-11x + 5 = -6Subtract 5 from each side:-11x = -11Divide each side by -11:x = 1
What is the derivative of y equals square root of 8x plus square root of 4x?
y=(8x).5 + (4x).5 = (2+2sqrt(2))x.5 y'=(1 + sqrt(2))/sqrt(x)
How do you write 8x plus 4y equals 5?
8x plus 4y equals 5 is 8x + 4y = 5.
How do you write 8x plus 4y equals 20 in fuction form?
8x+4y=20 4y=-8x+20 y=-2x+5 f(x)=-2x+5
Which type of lines match these equations 4y plus 8x equals 20 y equals -2x plus 5?
The two equations represent the same straight line.
Are 3x-4y equals -5 and 8x plus 6y equals -5 parallel or perpendicular lines?

What is 4y plus 5 plus 3 equals 35?
6.75
4y plus 4 equals 3y-5?
4y + 4 = 3y - 5 y = -9
6x plus 4y equals 32 -6x plus 4y equals 8?
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
What is 4 plus 8x equals 39 plus x?
5
5x - 5y equals -30 3x plus 4y equals 38?
Add the equations: 8x - y = 8 ie 8x - 8 = y so 5x - 5(8x - 8) = -30 which is 5x - 40x + 40 = -30 ie -35x = -70 making x = 2 and y = 8.
3x plus 2y equals 7 2x plus 4y equals 18?
