Answer:

(-2, 2), (0, 2), (7, 2), (11, 2)

Step-by-step explanation:

A relation must have no repeating x-values for it to be a function.

Set C does not have any repeating x-values, so it is a function.

Sets A, B, and D have repeating x-values, so they are not functions.

A: (0, 0), (2, 3), (2, 5), (6, 6)

B: (3, 5), (8, 4), (10, 11), (10, 6)

D: (13, 2), (13, 3), (13, 4), (13, 5)

What is the greatest common factor of the terms 14c to the second power D and 42 C to the third power d

irina [24]

Answer:

Step-by-step explanation:

To find the GCF we factor all the given terms and then find the Greatest Common Factor from both ,

So , The given two terms can be given by

$14c^2d = 2.7.c.c.d\\42c^3d =2.3.7.c.c.c.d\\$

Here common numbers that are in both are

2.7.c.c.d

so GCF= $14c^2d$

Solve the system of equations -x+ 2y = –11 and 5x – 8y = 39 by combining the equations.

Alchen [17]

Answer:

x=-5, y=-8. (-5, -8).

Step-by-step explanation:

-x+2y=-11

5x-8y=39

---------------

5(-x+2y)=5(-11)

5x-8y=39

---------------------

-5x+10y=-55

5x-8y=39

--------------------

2y=-16

y=-16/2

y=-8

-x+2(-8)=-11

-x-16=-11

-x=-11+16

-x=5

x=-5
