State which of the following ordered pairs is a function. Set A: (-1, 0), (-2, 1), (4, 3), (3, 4) Set B: (1, 4), (2, 3), (3, 2),

Mice21 [21]

Answer:

Both set A and B.

Step-by-step explanation:

Set A: (-1, 0), (-2, 1), (4, 3), (3, 4)

Set B: (1, 4), (2, 3), (3, 2), (4, 1)

Set C: (2, 1), (3, 2), (2, 3), (1, 4)

In order for (x,y) to be a function, only one x get the value of y, but many x'es can get the value y.

Looking at the set A and B, and the definition above, we can say that they are functions.

What about set C? It is not a function, as x = 2 is equal 1 or 3, which does not meet the condition from the definition.

W−2+2w=6+5w please helppp

Lerok [7]

Answer:

Step-by-step explanation:

Simplifying

W + -2 + 2w = 6 + 5w

Reorder the terms:

-2 + W + 2w = 6 + 5w

Solving

-2 + W + 2w = 6 + 5w

Solving for variable 'W'.

Move all terms containing W to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + W + 2 + 2w = 6 + 2 + 5w

Reorder the terms:

-2 + 2 + W + 2w = 6 + 2 + 5w

Combine like terms: -2 + 2 = 0

0 + W + 2w = 6 + 2 + 5w

W + 2w = 6 + 2 + 5w

Combine like terms: 6 + 2 = 8

W + 2w = 8 + 5w

Add '-2w' to each side of the equation.

W + 2w + -2w = 8 + 5w + -2w

Combine like terms: 2w + -2w = 0

W + 0 = 8 + 5w + -2w

W = 8 + 5w + -2w

Combine like terms: 5w + -2w = 3w

W = 8 + 3w

Simplifying

W = 8 + 3w
