7y + 2y = 9y 7y * 2y = 14y^2
Slope is found by this form. Y = mX + c ( m = slope ) - 5X - 7Y - 6 = 0 ( I assume this is what you mean ) - 7Y - 6 = 5X - 7Y = 5X + 6 Y = - 5/7X - 6/7 The slope would be in this instance, - 5/7 ----------
Honey, that's not a linear equation, so there's no slope-intercept form to be found here. You've got a monomial mess on your hands with 9xy. If you want to simplify it, just leave it as 9xy. No need to force it into a form it doesn't belong in.
A number is in exponential form when it is written with a base and an exponent.
If you mean: 13x+2y-10x-7y then it is an algebraic expression that can be simplified to 3x-5y
You mean like these?: 9 * 2 - (-2 + 9) + 15 / (4.5 + 3) (6x + 7y) * 2 (y - 6x)=(6x*2y)-(6x*12x)+(2y*7y)-(12x*7y)=12xy-72x^2+14y^2-84xy=14y^2-72x^2-72xy
7y + 2y = 9y 7y * 2y = 14y^2
-4
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
217

If you mean: 32-10x+7y = 0 then as a straight line equation it is 7y = 10x-32
the mean (in math) is the average of all the numbers in the problem
Mathematics is not mean. It is the purest form of knowledge!
nothing is important on math
If you mean: 3y^2-7y+3-5y+3-4y^2 then it is simplified to -y^2-12y+6
If you mean: x+7y = 39 and 3x-2y = 2 Then by substitution: x = 4 and y = 5
