What is the inverse to the statement x equals y?
x=y is the identity. It is its own inverse. So the inverse is y=x.
The pseudocode If-Then statement that assigns 0 to x if y is equal to 20?
Pseudocode is generally a very loosely defined concept. Various ways you can show your statement: if y = 20 then x = 0 if( y == 20 ) x = 0 if y is 20 then set x to 0
What is the negation of x plus y equals 10?
choose the negation of this statement. x plus y equals 10
What is the solutions for this problem 3x plus y equals 7 x equals 2y?
So we have a statement that 3x + y = 7x = 2y. Can we find some values for x and y that will satisfy the statement?Suppose the statement is true, then we have3x + y = 7x, which yields y = 4x. or3x + y = 2y, which yields y = 3x.Thus, 4x = 3x, if and only if x = 0, which also yields y = 0.Therefore, the given statement is true only for x = 0 and y = 0. For other values of x and y, it is a false statement.If there are two equations such as 3x + y = 7 and x = 2y, then substitute 2y for x into the first equation.3(2y) + y = 76y + y = 77y = 7y = 1, thus x = 2y = 2(1) = 2.Therefore the solution point is (2, 1),
What is biconditional statement?
A bi-conditional statement is one which says that if any one of two statements is true, the other is true, too. It generally takes the form, X is true if and only if Y is true, or X is equivalent to Y, where X and Y are simpler statements.
