-2x+2x
It is just an algebraic expression y+3. It means add 3 to y.
It means whatever x is, multiply it by 3 and add 10
You can expand the first expression in parentheses, then add or subtract like terms.
2 plus 2y plus x plus x y = 2 plus3y plus 2x (find how many X's there are and add them together and ten Y's and then single numbers)
-2x+2x
It is the same as 54 plus 36 and both expressions add to 90
Twice a number can be represented as 2x, where x is the unknown number. Adding 27 to this expression gives 2x + 27. Therefore, "twice a number plus 27" can be written as the algebraic expression 2x + 27.
You would add 'non' to the beginning so it becomes 'nonlinear'.
If you know the value of "n", you can replace it in the expression, then add. Otherwise, you have to keep them separate. You can still factor the expression, if you like, but that really won't make it any simpler.
It is just an algebraic expression y+3. It means add 3 to y.
It means whatever x is, multiply it by 3 and add 10
It's a polynomial of degree 1.
No. In the variable x, alone, it is linear. In the variable y, alone, it is linear. But taken together, in x and y, you have a term which contains xy - that is, a term in which the powers of the unknowns add to 2. So the equation is not linear.
It is an algebraic expression. It requires the user to multiply any given number by 3 and then add 7.
Freedom of expression and freedom of speech
