Since you know the values of the two variables, a and y, plug it into the expression like this: 2a3 - 3ay = 6a - 3ay = 6(-1) -3(-1)(2) = -6 -3(-2) =-6 + 6 = 0

The difference between undefined slope and zero slope is?
The slope of a line between Points 1 and 2 is defined as m = (Y2 - Y1) / (X2 - X1) where coordinates for Point 1 is (X1,Y1) and Point 2 is (X2,Y2). So if the value of Y2-Y1 = 0 then the Slope is zero. If the value of X2 - X1 = zero then the equation is undetermined because you can't solve an equation with a 0 value in the denominator. or m = (Y2 - Y1) / 0
How do you evaluate an algebraic expression?
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.
If you have an equation of 12x plus 1 what is x?
Without an equality sign the given expression is not an equation and so therefore finding the value of x is not possible.
How do you solve x plus 1 over x?
You don't "solve" an expression. You can solve an equation; an expression can be simplified or otherwise manipulated, and if you know the value of "x" (in this case), you can evaluate its value.
What value of x makes the expression x undefined?
+1/0 or -1/0 or 0/0
What is the reciprocal of y to the negative 2 power?
The expression Y-2 is 1/Y2. The reciprocal of 1/Y2 is Y2.
What equation is 3x-y2?
1
What are the points that lie on the line 3x-y2?
1
What is the expression and value of 1 to the power of 6?
The expression would be written as 16 The value of the expression is 1. 1 x 1 x 1 x 1 x 1 x 1 = 1
What type of equation has the variable in the denominator of an expression?
x = 1 / y2 where: x is the dependent variable y is the independent variable
What is the value of 3x2 - y2 if x equals -1 and y equals 3?
x = -1y = 33x2 - y2 = 3 (-1)2 - (3)2 = 3 (1) - 9 = -6
Convert x2 plus y2 equals 2x?
What do you want to convert it to? x2 + y2 = 2x If you want to solve for y: x2 + y2 = 2x ∴ y2 = 2x - x2 ∴ y = (2x - x2)1/2 If you want to solve for x: x2 + y2 = 2x ∴ x2 - 2x = -y2 ∴ x2 - 2x + 1 = 1 - y2 ∴ (x - 1)2 = 1 - y2 ∴ x - 1 = ±(1 - y2)1/2 ∴ x = 1 ± (1 - y2)1/2
The difference between undefined slope and zero slope is?
The slope of a line between Points 1 and 2 is defined as m = (Y2 - Y1) / (X2 - X1) where coordinates for Point 1 is (X1,Y1) and Point 2 is (X2,Y2). So if the value of Y2-Y1 = 0 then the Slope is zero. If the value of X2 - X1 = zero then the equation is undetermined because you can't solve an equation with a 0 value in the denominator. or m = (Y2 - Y1) / 0
Is it true When the base of an exponential expression is 1 the value of the expression always equals 1?
Yes.
Which expression is equivalent to x-1 y2?
If you should mean x-1 = 2y Solved for x: x = 2y + 1 Solved for y: y = (x-1)/2
Is 6x 1-5 a linear equation?
equation is an expression equated to a value..what you have written is an expression. when equated to a value or any other expression makes it an equation.
What is the value of the expression 3a-1 when a is 5?
14
