Adding which of the following ordered pairs to the set {(1,-2), (0,4), (2,-3)} would make it not a function?

, -2)
b. (3, 5)
c. (0, 2)
d. (-2, 1)

Option C. (0, 2)

Step-by-step explanation:

we know that

A function can only have one y value for each x value, so you can't repeat the same x value

In this problem we have the set

{(1,-2), (0,4), (2,-3)}

If you adding the ordered pair (0,2)

then

For x=0

will have two values of y

y=4 and y=2

therefore

The ordered pair (0,2) would make the set not a function

Correct option is:

C.  (0,2)

A set of ordered pairs is a function as long as no two ordered pairs have the same first coordinate with different second coordinates.

we are given a ordered pair:

{(1,-2), (0,4), (2,-3)}

A.(-1, -2)

If we add it to above set of ordered still it will be a function

B. (3, 5)

If we add it to above set of ordered pair  still it will be a function

C. (0, 2)

If we add it to above set of ordered pair then first coordinate 0 will have two different second coordinate i.e. 2 and 4

and the ordered pair will no longer be a function then

D. (-2, 1)

If we add it to above set of ordered pair  still it will be a function

Correct option is:

C.  (0,2)

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

answer: your correct answer is b. d.
