Find the value of 2 numbers if their sum is 12 and their difference is 4?
x+y=12 x-y =4 x=12-4 =8 8+y=12 y=12-8 =4 so x=8 y=4 8+4=12 8-4=4
What is the soultion of y -8 and y -2x-12?
If you mean: y = -8 and y = -2x-12 then the solution is x = -2 and y = -8
Three times one number minus a second is eight and the sum of the numbers is twelve?
3x-y=8 x+y=12 3x(12-x)=8 3x-12+x=8 4x-12=8 4x=20 x=5 x+y=12 5+y=12 y=7
-x+ 4 y>-8 x+y8 y?
-x+ 4y>-8, x+y≤3 y≤3-x -x+4(3-x)>-8 -x+12-4x>-8 12-5x>-8 -5x>-20 x>4 y≤3-(4) y≤-1
If y varies directly with x find the constant of variation if x equals 8 and y equals 12?
y = cx when x = 8, y = 12 so that 12 = 8c which gives c = 12/8 = 1.5
Is x plus y a monomial?
no. x is one term, and y is another term, so x+y has two terms, meaning it is a binomial
What is an example of a monomial?
A monomial is an algebraic expression with only one term. One example of a monomial is 4x. Other examples are 4x^2 or 8/y
What is x y 12 and x - y 4 using the addition method?
16
Evaluate the following expression if x equals 12 y equals 8 and z equals 6?
x=y-8 z=x+12
What are the steps in finding the common monomial factor?
To find the common monomial factor of a set of monomials, first identify the variables and their corresponding exponents in each monomial. Next, determine the smallest exponent for each variable that appears in all the monomials. Finally, combine the variables with their corresponding smallest exponents to form the common monomial factor. This factor will be the largest monomial that can be factored out from each original monomial.
What sum of two numbers is 8 and their difference is 12 Find the numbers?
Let X be one number and Y the other. So, X + Y = 8 and X - Y = 12 Solve the set of equations simultaneously or use substitution method. X + Y = 8 X - Y = 12 (ADD THIS EQUATION TO FIRST ONE) _______________ 2X = 20, So X =10 and solving for Y using either equation, Y = -2
What is 8 times a number x decreased by y?
It is difficult to tell what expression you are trying to convey. 8 multiplied by x, and then take y away, is 8x-y x take away y, and then 8 multiplied by this number, is 8(x-y) 8 multiplied by x, and divided by y is 8x/y
