ANSWER:

(2ab - 3c)(2ab + 3c)

Using identity (a + b)(a - b) = a² - b².

(2ab)² - (3c)²

4a²b² - 3c².

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

4x + 5y = -12

-2x + 3y = -16

Step 2: Rewrite Systems

-2x + 3y = -16

Multiply everything by 2: -4x + 6y = -32

Step 3: Redefine Systems

4x + 5y = -12

-4x + 6y = -32

Step 4: Solve for y

Elimination

Combine 2 equations: 11y = -44
Divide 17 on both sides: y = -4

Which statement is correct about relations and functions?

aniked [119]

Definition 1: A relation is any subset of a Cartesian product. For instance, a subset of $A\times B$ , called a "binary relation from A to B," is a collection of ordered pairs (a,b) with first components from A and second components from B, and, in particular, a subset of $A\times A$ is called a "relation on A."

Definition 2: A function is a relation that associates each element x of a set X to a single element y of another set Y (possibly the same set). A function is uniquely represented by its graph which is the set of all ordered pairs (x, f (x)).

From these definitions you can see that every function is a relation from X to Y, but not via versa (because you can consider relation $\{1\}\times \{2,3\}$ - here for one x exist two y).
