The filled in dot means inclusive and the hallow dot means exclusive. For an inequality, inclusive will mean it can be equal to that number as well as being less or greater than. Exclusive means the opposite.
In terms of x, the number line shows that -2 <= x < 2.
Answer:
The ordered pairs that are presented are (7, 99.5) and (3, 51.5)
Step-by-step explanation:
We are given the cost function of the carnival rides as

which is a typical linear expression of the form
where here
,
,
and
. To check if an ordered pair i.e. a point
, is represented by the table we can simply plug in the equivalent
value in the equation, and check if the result matches the
value.
So, lets assume that all points are given correctly and they are as follow:

Now let us check each point with our function as follow:
<u>Point A</u>

So point A is part of the equation.
<u>Point B</u>

So point B is NOT part of the equation.
<u>Point C</u>
<u />
<u />
So point C is part of the equation.
<u>Point D</u>
<u />
<u />
So point D is NOT part of the equation.
Answer:
Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio--that is, when you divide any pair of the two values, you always get the same number k.
Your answer is 80 mins, or an hour and 20 mins. You simply turn that fraction to a decimal by diving 3 with 5. This should turn out to be 0.6. Then you multiply the 24 mins with the 2 miles and it turns out to be 48. After this, you divide 48 by 0.6 and you get 80.
