If 4y plus 10 equals 22 what does y equal?
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3
What does like terms mean?
Like terms are terms with the same variable to the same power. Examples: 2y and 3y are like terms. 2y and 2z are not like terms 4y squared and 3y squared are like terms 4y squared and 3y are not like terms
Subtract 4y cubed plus 2y squared plus y from 5y cubed - y?
9y cubed plus 2y squared
What are the points of intersection when the line x -y equals 2 crosses the curve x squared - 4y squared equals 5?
If: x -y = 2 then x^2 = y^2 +4y +4 If: x^2 -4y^2 = 5 then x^2 = 4y^2 +5 So: 4y^2 +5 = y^2 +4y +4 Transposing terms: 3y^2 -4y +1 = 0 Factorizing the above: (3y -1)(y -1) = 0 meaning y = 1/3 or y = 1 Substitution into the original linear equation intersections are at: (7/3, 1/3) and (3, 1)
What does 9a squared equal?
9a squared = 81a^2
What is x squared-xy-20ysquared equal?
This equation does not equal a number, but it can be factorised. x2-xy-20y2=(x-5y)(x+4y)
How do you solve x squared minus 2x minus 4y squared minus 4y?
The answer to x2 - 2x - 4y2 - 4y =(x - 2y)(x - 2y - 2)
What is 9x squared minus 16y squared factored?
This is a difference of two squares, which factorises to: (3x - 4y)(3x + 4y)
Factor 25x squared minus 4y squared?
(5x - 2y)(5x + 2y)
Does 2y squared equals 4y?
No, it equals 4y2
If 4y plus 10 equals 22 what does y equal?
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3
2xy + 2xy squared?
(x + 4y)(x - 6y)
Factor 4x squared plus 8xy plus 4y squared?
4(x+y)^2
If 4y 929 what is y equal?
4y = 929 4y/4 = 929/4 y = 232.25
How do you plot 3x plus 4y equal 60?
plot 4y then 3x
What does like terms mean?
Like terms are terms with the same variable to the same power. Examples: 2y and 3y are like terms. 2y and 2z are not like terms 4y squared and 3y squared are like terms 4y squared and 3y are not like terms
