A general statement is needed

Check if the following statement is TRUE or FALSE. 2 Let X and Y be two real numbers satisfying x² + y² = 0. Then x = 0 or y = 0. True O False

Simplify the following expression (Don't forgot attach your domain!) 2. -5x+4 2. x´ - 4x *You don’ t have to print this organizer for working but just follow it's direction & format.

I just need clarification on why the answer isn't 14

Determine which statement completes each open sentence: 3x - 4 + x 3(x - 4 + x) when x = 4 3x - 4 + x 3(x - 4 + x) when x = 2 1. is equal to 4? 4 • 2 2. is NOT equal to 32 - 8 + 1 32 - 1 15 (1 + 2) -_ 15 ÷ 1 + 2 > >

22. What property is NOT illustrated in the statement ? (1)(n) = (n)(1)? b. Commutative property c. Identity property a. Closure property d. Distributive property

Write the following statement as a mathematical statement. Use variable names to denote arbitrary numbers in the domain. Your statements and should be expressed using algebra. "There is no largest integer."

For "x is in the symmetric difference of A and B" give an equivalent statement that uses "x is in A"  and "x is in B".

For each statement below, decide whether that statement is true or false.

The algebraic translation of "x is no less than 7" is .
