Which of the following relations is NOT a function?

1 answer:

5 0

According to Wikipedia: "In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output."

So based of this we need to look for a set where one of the x values or the y values is the same, and the other number is different.

Answer:
B.
(1,4) and (1,1) both have the same x, but different y!

Find the measure of angle CKJ if the measure of angle LKC is x + 96, the measure of angle LKJ is 131 degrees, and the measure of

svet-max [94.6K]

Answer:

The measure of angle CKJ is 44°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠LKJ=m∠LKC+m∠CKJ ----> by addition angle postulate

substitute the given values

$131\°=(x+96)\°+(x+53)\°$

solve for x

$131=2x+149$

$2x=131-149$

$x=-9$

Find the measure of angle CKJ

m∠CKJ=(x+53)°

substitute the value of x

m∠CKJ=(-9+53)=44°
