An expression that can only provide a single solution, y, for any given input, x, is called a “function”.

The given pairs are in the form (x,y)

Looking at set A:

(4,-2), (-2, 2), (2,-2), (4, 2)

Notice that if x=2, there are 2 y’s, -2 and 2. Therefore this set is not a function.

A. Find value of x and KL if K is between J and L.
MrRa [10]

Answer:

x=3

Step-by-step explanation:

If k is between J and L, then

JK + KL = JL

2x+11 + (3x) = 13x-13

Combine like terms

5x +11 = 13x -13

Subtract 5x from each side

5x-5x+11 = 13x-5x-13

11 = 8x-13

Add 13 to each side

11+13 = 8x-13+13

24 = 8x

Divide by 8

24/8 = 8x/8

3 =x
