How do you find the least common multiple of 6x to the power of y and 12x to the power of 4 y?
Since the second one is a multiple of the first, it is automatically the LCM.
What is the GCF of of 32xy 20y to the second power?
The GCF is 4y.
How do you factor 9x to the fourth power minus 16y to the fourth power?
(3x^2 - 4y^2)(3x^2 + 4y^2)
-x +4y=20 -7x+4y=-4?
Assume the first equation is E1: -x+4y=20 Assume the second equation is E2: -7x+4y = -4 Since both equation include 4y, we could eliminate y first. So E1 - E2: -x+4y - (-7x+4y) = 20 - (-4) -> -x+4y+7x-4y = 24 -> 6x = 24 -> x = 4 Thus substitute x = 4 to either E1 and E2, and I will just substitute it into E1: -x + 4y = 20 -> -4 + 4y = 20 -> 4y = 24 -> y = 6 Therefore, x = 4 and y = 6
What is the GCF of 4y 8x to the third power?
4
How do you get the greatest common factor and least common multiple having variable and exponents?
For the GCF, choose the lowest of each exponent. For the LCM, choose the highest. Example: x^2y^3z^4 and x^4y^5z The GCF is x^2y^3z The LCM is x^4y^5z^4
4y 2nd power equals 3- 5?
4y2
If 4y plus 10 equals 22 what does y equal?
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3
What is 4y 8y?
4y + 8y = 12y 4y - 8y = -4y 4y x 8y = 32y2 4y/8y = 1/2
What must be added to 11x plus 2y to produce 10x-4y?
Add -x -6y. Just like with numbers, subtract the first from the second to find what to add to the first to get the second; keeping like terms together: (10x - 4y) - (11x + 2y) = (10x - 11x) + (-4y - 2y) = (10 - 11)x + (-4 - 2)y = -x - 6y
If you were to solve the following system by substitution what would be the best variable to solve for and from what equation 2x plus 6y equals 9 3x-12y equals 15?
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
What is the name of this function 4y plus 8 equal to 3x to the power of 2 minus 2x plus 1?
if you rearrange it, it becomes 4y + 8 = 3x2 -2x +1 4y = 3x2 -2x -7 y= (3x2 -2x -7)/4 which is a parabola
