Oh, dude, 7y in math is just like saying "7 times y." It's like when you have 7 slices of Pizza and y represents how hungry you are. So, if y is 2, you'd need 14 slices to satisfy your hunger. Math can be deliciously confusing, right?
7y + 2y = 9y 7y * 2y = 14y^2
The slope intercept form is: y = mx + b 9x + 7y = 15 9x - 9x + 7y = 15 - 9x 7y = - 9x + 15 y = -(9/7)x + 15/7
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 ----------
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
The slope intercept form is: y = mx + b 9x + 7y = 15 9x - 9x + 7y = 15 - 9x 7y = - 9x + 15 y = -(9/7)x + 15/7

If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
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 ----------
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: x+7y = 39 and 3x-2y = 2 Then by substitution: x = 4 and y = 5
