Answer:

a relation and function ⇒ answer C

Step-by-step explanation:

* Lets revise the relation and the function

- The relation is between the x-values and y-values of ordered pairs.

- The set of all values of x is called the domain, and the set of all values

 of y is called the range

- The function is a special type of relation where every x has a unique y

- Every function is a relation but not every relation is a function

* Lets solve the problem

∵ The graph is a parabola

∵ The parabola is a function because every x-coordinates of the

   points on the parabola has only one y-coordinate

- Ex: some ordered pairs are (-5 , -5) , (-2 , 5) , (0 , 7) , (2 , 5) , (5 , -5)

∵ Every x-coordinate has only one y-coordinate

∴ The graph represents a function

∵ Every function is a relation

∴ The set of ordered pairs in the graph below can be described as

   a relation and function

Paul worked as a library volunteer for 8 ¼ hours. Harry worked for 3 ½ hours. How much longer did Paul work than Harry?
stiks02 [169]

Answer:

4 3/4

Step-by-step explanation:

= (8 - 3) + (1/4 - 1/2)

= 5 + 1/4 - (1 x 2 over 2 x 2)

= 5 + 1/4 - 2/4

= 5 and (1/2 over 4)

= 5 + -1/4

= 4 3/4

Gary has twice as many m&amp;ms as larry. Jerry has three times as many m&amp;ms as larry. Together the tree men have 108 m&amp;
Igoryamba

Answer:

36

Step-by-step explanation:

Let number of m&ms Garry has be g

number of m&ms Larry has be l

Number of m&ms Jerry has be j

Since Gary has TWICE as Larry, we can write:

g = 2l

Also, Jerry has THRICE as Larry, we can write:

j = 3l

Together, they have 108, thus, we can write:

g + l + j = 108

Putting 1st and 2nd equation in 3rd, we can solve for Larry first. Shown below:

g + l + j = 108\\2l+l+3l=108\\6l=108\\l=\frac{108}{6}\\l=18

Larry has 18. To find Gary's number, we can use the fact g = 2l, so

g = 2 * 18 = 36

Gary has 36 m&ms
