What is the equation to y is twice x?
y=2x
What is the value of the expression x-y squared when x equals 7 and y equals negative 2?
If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81. If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.
What is the expression for x equals 3 and y equals 6?
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
What is a solution of y - x -3?
y - x - 3 is an expression, not an equation nor an inequality. It cannot, therefore, have a solution.
What is the value of the expression 4x-2y plus xy when x equals -1and y equals 5?
To find the value of the expression 4x - 2y + xy when x = -1 and y = 5, we first substitute the values of x and y into the expression. This gives us 4(-1) - 2(5) + (-1)(5). Simplifying this further, we get -4 - 10 - 5, which equals -19. Therefore, the value of the expression is -19 when x = -1 and y = 5.
What is the algebraic expression of y plus the product of -5 and x?
y - 5x
What is an expression for the product of x and y?
x times y or, symbolically, either x*y or simply xy (where context allows, also X x Y)
Which expression gives the result when x is subtracted from the product of y and z?
yz - x
Twice the sum of x and y and The sum of twice x and y?
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
What is an algebraic expression of the quotient of a number x and seven less twice the number y?
x / (2y - 7)
Three times the product of twice a number y and x?
3(2y)(x)6xy
What is the difference between twice the sum of x and y and the sum of twice x and y?
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
How do you write one half the product of x and y as an algebraic expression?
0.5*xy
How do you right this expression 4x plus 4y as a product using parentheses?
4(x+y)
Y plus the product of -5 and x?
This phrase might be represented by the mathematical expression Y + (-5x). Because there is no additional information, you cannot determine what either Y or x is.
How do you turn the difference between 15 and the product of 5 and y into an algebraic expression?
X = 15 - 5y
What is xy plus z?
The expression xy + z represents the sum of the product of x and y with the value of z. This is a simple algebraic expression where x and y are variables representing numbers, and z is a constant value. To find the result of xy + z, you would first multiply x and y, and then add the value of z to the product.
