How do you factorize 9 multiplied by x square plus 24 multiplied by x and y plus 16 multiplied by y square?
9x2 + 24xy + 16y2 = 9x2 + 12xy + 12xy + 16y2 = 3x(3x + 4y) + 4y(3x + 4y) = (3x + 4y)*(3x + 4y) = (3x + 4y)2
What would x and y be if the equation is 3x-4y equals 10 and -3x equals 4y equals 8?
3x - 4y = 10-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 100x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3
What is the slope of the equation 3x plus 4y equals 8?
It is:- 3x+4y = 8 4y = -3x+8 y = -0.75x+2 So the slope is -0.75 and the y intercept is 2
What is the slope to 3x plus 4y equals 12?
3x + 4y = 12 Subtract 3x from each side 4y = 12 - 3x Divide by 4 on each side y = 3 - .75x The slope is what is multiplied by "x" or -.75
How can you convert 3x plus 4y equals 4 into slope-intercept form?
3x+4y = 4 4y = -3x+4 y = -3/4x+1 So the slope is -3/4 and the intercept is 1
What is 3x - 4y?
3x - 4y = -1
What is -4y?
3x+4y = 17 -3x -3x 4y = -3x+17 Divide each TERM by 4 y = -3x + 17 4 4
What is 3x 4y-17?
3x+4y = 17 -3x -3x 4y = -3x+17 Divide each TERM by 4 y = -3x + 17 4 4
What the answer for this 3x plus 4y?
It is: 3x+4y which is an algebraic expression
What is 3x times 4y equals?
12xy
How do you factorize 9 multiplied by x square plus 24 multiplied by x and y plus 16 multiplied by y square?
9x2 + 24xy + 16y2 = 9x2 + 12xy + 12xy + 16y2 = 3x(3x + 4y) + 4y(3x + 4y) = (3x + 4y)*(3x + 4y) = (3x + 4y)2
Can you multiply unlike terms?
Yes, you can. For example 3x times 4y = 12xy.You cannot however, add like terms (to combine them, that is. There isn't anything wrong with adding them up, 3x + 4y is acceptable). For example, 3x + 4y is as simplified as it can get.
What is the answer 3x equals 4y-x?
3x=4y-x 4x=4y x=y
What equation is equivalent to 3x - 4y 8?
3x - 4y = 8Solve for x:3x = 4y + 8x = 4/3y + 8/3Solve for y:-4y = -3x + 8y = 3/4x - 2
How do you plot 3x plus 4y equal 60?
plot 4y then 3x
What equation is equivalent to 3x-4y equals 8?
3x - 4y = 8Solve for x:3x = 4y + 8x = 4/3y + 8/3Solve for y:-4y = -3x + 8y = 3/4x - 2
Simplifying rational expressions 6x-5y plus -3x-4y?
(6x - 5y) + (-3x - 4y) =6x - 5y - 3x - 4y =3x - 9y =3 (x - 3y)
