It would have a lot different kinds!!
Answer:
Step-by-step explanation:
From the given information:
The Directrix x = - 1
The eccentricity e = 1
Since the Directrix x = - 1, it implies that the directrix appears on the left negative side of the pole and is vertical.
Hence, the conic equation in terms of r is:

From the directrix to the pole, the distance p = 1
So;


Answer:

Step-by-step explanation:
Cost of one dress = 
Cost of one pair of shoes = 
Cost of one dress and a pair of shoes is 
They get half off the price because they buy both

The shipping and handling charge is
.
So, the total amount Ruth has to pay is
.
To write an equation and simplify it, I'll start with this:
$4,500 = $90 + $39X Let X represent the amount of people attending the party.
Subtract 90 and both sides of the equation to make the $39X alone.
$4,410 = $39X
Divide $39 into both sides of the equation to isolate or bring X alone.
113.076923 = X
Now since we have to round down, we will do 113.
Answer: 113 people can attend the anniversary party.
Simplify x - 3/3 to -1 + x/3
regroup terms
multiply both sides by 6 (The LCM of 2,3)
expand
subtract 2x from both sides
simplify 3x + 12 - 2x to x + 12
subtract 12 from both sides
simplify -6 - 12 to -18
Answer: x = -18.
