The parabola opens in the direction of the focus.
Since the focus is above the vertex, it opens up.

Divide the whole equation by 2
Answer:
$91.75
Step-by-step explanation:
She earns $2.15 an hour and worked 20 hours this week so
20 × 2.15 = 43 and she earned 15% tip off the meals she served
to calculate how much 15% of 325 does we multiply 325 with 15 and divide it with 100
325 × 15 ÷ 100 = 48.75
48.75 + 43 = 91.75
The median is 7.

Arrange data in numerical order
1 3 3 6 8 10 10 15
Total number are 8, N = 8
Take the middle two numbers 6 and 8 and take their average
6+8/2 = 14/2 = 7
Therefore the median is 7.
The answer is: x = 10, y = 2
Leave a thanks because your welcome :)
Work:
x + y = 12
(10) + (2)+ = 12
Correct
x - 2y = 6
(10) - 2(2) = 6
10 - 4 = 6
Correct
