Factor of 7y2 plus 2y-5?
(7y - 5)(y + 1)
What is y3 plus 7y2-5y?
That factors to y(y2 + 7y - 5)
What is a binomial coefficient?
A binomial coefficient is a coefficient of any of the terms in the expansion of the binomial (x+y)^n.
What is the coefficient of x 12 y 13 in the expansion x plus y 25?
It is 5200300.
Is the slope of a line the coefficient of the x term in the line's equation?
Yes, but only when the coefficient of y is 1. For example if the equation of the line is 3y = 2x + 5, then the slope is not 2. The equation has to be re-written as y = 2/3*x + 5/3 whence the slope IS 2/3
Factor of 7y2 plus 2y-5?
(7y - 5)(y + 1)
What is y3 plus 7y2-5y?
That factors to y(y2 + 7y - 5)
What is coefficient of a number?
A coefficient is a factor to a variable in a given expression. While they may be represented with algebraic expressions, they are typically to be treated like constants. For instance, in y = 5x 5 is a coefficient of x. Similarly, in y = ax a is a coefficient of x.
How would you factor 8x2 - xy - 7y2 The 2 after the x and y are the squares. so its 8x squared - xy - 7y squared.?
You can factor this multivariate polynomial (a polynomial with several variables, here x and y), by looking at it as a univariate polynomial in either x or y. This would give you a simple second order equation of the form ax2+bx+c, which you can solve. This will give you 2 solutions, say x1 and x2, and can then factor your polynomial to a(x-x1)(x-x2). In our case: a=8, b=-y and c=-7y2 and the solutions for this equation are x1=y and x2=-7/8*y and this gives us 8x2 - xy -7y2 = 8(x-y)(x+7/8y) = (x-y)(8x+7y)
What is the coefficient of x in 3xy?
-3xy is a monomial where x and y are variables and -3 is the coefficient of the monomial.If we know the value of y, we have to substitute it for y, and we say that -3(y-value) is the coefficient of x.
What is the numerical coefficient of y in 5y?
The numerical coefficient of y in 5y is 5. In an algebraic term, the coefficient is the number that is directly multiplied by the variable. In this case, y is being multiplied by 5, making 5 the coefficient of y in the term 5y.
What is the slope Y equals -4x plus 5?
slope = coefficient of x = -4
What is the numerical coefficient of -5y?
The numerical coefficient of -5y is -5. In algebraic terms, the coefficient is the numerical factor that is multiplied by the variable. In this case, the variable is y, and the coefficient is -5, indicating that -5 is multiplied by y.
The vertex of this parabola is at 5 5 When the x-value is 6 the y-value is -1 What is the coefficient of the squared expression in the parabola's equation?
The vertex of this parabola is at 5 5 When the x-value is 6 the y-value is -1. The coefficient of the squared expression in the parabola's equation is -6.
In the slope intercept what coefficient gives the slope?
Th formul for slope-intercept is y=mx+b. y= the y-coordinate m= the slope x= the x-coordinate b= the y-intercept Therefore if your equation was y=3x+5 then the coefficient that gives the slope is 3.
What is y times 7y?
Yx7y = 7y2 (squared )
What is the coefficient of xy?
The coefficient of xy is the number that multiplies the product of x and y in a given expression. For example, in the expression 5xy, the coefficient of xy is 5.
