Answer:
E: L is perpendicular to a line with slope .
Lines are perpendicular if the negative reciprocal of the slope is equal. For example, the reciprocal of is
(remember, to get the reciprocal, simply switch the numerator and the denominator).
So, the negative reciprocal of is
. This represents the slope of a line that is perpendicular.
Answer:
The adult tickets are <u>400</u> and the children tickets are <u>300</u>.
Step-by-step explanation:
Given:
At a carnival, 700 tickets were sold for a total amount of $5500. An adult ticket cost $10 and a children's ticket cost $5.
Now, to find the number of adult tickets and the number of children's tickets sold.
<em>Let the number of adult tickets be </em><em />
<em>And let the number of children tickets be </em><em />
So, the total number of tickets sold:
Now, the total amount of tickets:
Substituting the value of from equation (1):
<em>Subtracting both sides by 3500 we get:</em>
<em /><em />
<em>Dividing boths sides by 5 we get:</em>
<u />
<u>The number of adult tickets = 400.</u>
Now, substituting the value of in equation (1) we get:
<u>The number of children tickets = 300.</u>
Therefore, the adult tickets are 400 and the children tickets are 300.
