Step-by-step explanation: The easiest way to tell whether or not this relation is a function is to look at the x-coordinates of the given ordered pairs.

If any of the ordered pairs in this relation have the

same x-coordinate, then the relation is not a function.

In the last relation, all the x-coordinates are different.

So we can say the last relation is a function.

The table shows the number of toys sold at Penelope's Toys and Games store in different years. Find the rate of change in the nu

Aliun [14]

Answer:

Year - (1993 - 1995)

Step-by-step explanation:

Rate of change in the number of toys sold = $\frac{\text{change in number of toys sold}}{\text{Time interval}}$

In the interval (1990 - 1993),

Rate of change in number of toys sold = $\frac{32000-20000}{1993-1990}$

= $\frac{12000}{3}$

= 4000

In the interval (1993 - 1995),

Rate of change = $\frac{42000-32000}{1995-1993}$

= $\frac{10000}{2}$

= 5000

In the interval (2000 - 1995),

Rate of change = $\frac{57000-42000}{2000-1995}$

= $\frac{15000}{5}$

= 3000

In the interval (2006 - 2000),

Rate of change = $\frac{63000-57000}{2006-2000}$

= $\frac{6000}{6}$

= 1000

Therefore, rate of change in the number of toys sold is greatest in the interval (1993 - 1995).

Answer:

3s + 7.99 = 71.83

Step-by-step explanation:

How would we find out in real life how much each shirt cost? We'd subtract 7.99 from 71.83 and divide the difference by 3, right??

Let's work that backward. Let's say a shirt cost $6. Three would cost $3(6), or $18. Since each shirt costs $s, our price for 3 shirts is $3s. We have to add shipping to get a total, which we are given. When writing an equation, we leave out labels like $ or meters or books or whatever.
