There are 3 people in Jacobs family . The range of their shoe size is 3. Two people in the family wear shoe size 6 Jacobs shoe size is not 6 and it is not 3 . What is Jacobs shoe size

9

Step-by-step explanation:

Range = Highest Value - Lowest Value

Range of the shoe size in Jacob's family=3

Two people in the family wear shoe size 6.

Since Jacob's size is not 6 and it is 3.

Let Jacob's size =x

The shoe sizes are therefore: 6,6,x

Therefore:

x-6=3

x=3+6=

x=9

Jacob's shoe size is 9.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
