What does 4x plus 3y-2x plus y equal?
4x+3y-2x+y 4x-2x+3y+y 2x+4y Taking out 2 common 2(x+2y) Hence the required answer is 2(x+2y)
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)
Select the system of equations that corresponds to the given graph?
Answers to pick: -2x - y = 4 2x + y = -2 -8x + 4y = -16 -4x + 2y = -8 -x - 2y = 6 -7x + 4y = 16 2x + 3y = 6 3x + 2y = 4
-5x plus 2y equals 6 -9x plus 2y equals 22?
Subtract first from second gives -4x = 16 so x = -4 and y = -7
What does y equal in this equation 8x plus 6y equals 16 4x-2y equals 8?
x = 2, and y = 0. Here's one way to solve:Multiply the second equation (both sides) by 3, then add the two equations:8x + 6y = 1612x - 6y = 24----------20x = 40 ----> x = 2, then substitute x=2 into one of the original equations:8*2 + 6y = 16 --> 6y = 0, and y=0. Check with the other equation: 4*2 - 2y = 8 ---> -2y = 0, and y = 0.
What is the answer to 8x plus 2y equals 4?
8x+2y=4x=-y/4+0.5y=-4x+2
Solve 4x plus 3y equals 8x plus y for y?
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
X plus 7x plus 3y - y?
x+7x+3y-y =8x+2y =2(4x+y)
What is y in 8x plus 2y equals 10?
Y=5-4x to know how I got this do your home work
What is 4x x 2 in standard form?
y=4x*2y=8x
4x plus 2y equals -12 8x plus 6y equals -4?
x = -8, y = 10
Solve by substitution 3x plus 2y equals 6 4x-y equals 2?
4x-y=2, thereforey=4x-2sub y into 3x+2y=6...3x+8x-4=611x=10x=10/11
What is the Y intercept of 8x-2y-20?
If you mean: 8x-2y = -20 then y = 4x+10 whereas 4 is the slope and 10 is the y intercept
How do you graph the equation 8x plus 2y equals -1?
Same way you graph y = -4x - 0.5
What is -8x 2y-48?
If you mean -8x = 2y-48 then it is a straight line equation which can be expressed as y = -4x+24
What is the measure of the third side of a triangle where the perimeter is 8X plus 4Y and the others are X plus 2Y and 3X plus Y?
The perimeter of the triangle is 8x + 4y. The measures of two of the sides are x + 2y and 3x + y. If these two sides were added together, they would be 4x + 3y:x + 2y3x + y4x + 3yThe third side is the perimeter minus the two known sides, so 8x + 4y - (4x + 3y). Distribute the negative: 8x + 4y - 4x - 3y. This is equal to the third side, which is 4x +y.
What is the answer to 8x plus 2y equals -10?
8x + 2y = -10 As all terms have a factor of 2 then the values can be reduced accordingly. 4x + y = -5 If required, the equation can be re-written to show x or y as the subject. 4x + y = -5 : 4x = -y - 5 : x = (-y -5)/4........this can also be written as x = (y + 5)/-4 4x + y = -5 : y = -4x - 5
