Answer:
B & C
Step-by-step explanation:
I'm not sure if you can have two answers but both of them are linear. A And D aren't because they have absolute value
The Answer to your question is c focus: (0,3); directrix: y = -3. And if your taking the quick check here's all the answers to all four questions.
1.c
2.c x = -1/19y^2
3.d focus (-2,0): directrix: x = 2
4.c x = 1/10y^2

Answer:
<em>See the graph with both lines attached</em>
A) From the tables we see the constant change of values in the second column and the initial value is zero.
This represents a proportional relationship for both tables.
B) <u>Revel</u>
- Rate of change is 5 per hour, the equation is:
- y = 5x, where y is cost, x - is the number of hours
<u>Scooters</u>
- Rate of change is 6 per hour, the equation is:
- y = 6x, where y is cost, x - is the number of hours
C) <u>When x = 12</u>,
- y = 5*12 = $60 for Revel
- y = 6*12 = $72 for Scooters
D) <u>The point (4, 24) represents that:</u>
- The cost of 4 hours is $24
E) The second table has confusing titles (days and number of cell phones) but if we assume its same as the first table, then Revel has lower rate as 5 < 6.
Comparing the prices and the graph, Revel has better rate per hour.
