Answer:
x = -3/2y + 3
Step-by-step explanation:
2x + 3y = 6
2x = -3y + 6
x = -3/2y + 3
Answer:
a) see the attached file
b) Coordinates of vertex = (0, 4)
Step-by-step explanation:
Given:
Focus of parabola is and the directrix is
To sketch: the parabola
To find: coordinates of the vertex
Solution:
As the focus lies on the y-axis and y-coordinate of the focus is positive,
equation of parabola is
Here, denotes the vertex of parabola, focus is and the directrix is
According to question,
So,
On adding these equations,
Put in
So, equation of parabola is
For part a), see the attached file.
b)
Coordinates of vertex =
The ratio walkers/riders is
hence
the number of riders is times the number of walkers<em />-----------------------------------------------------------

Top right answer
43 and 5/6 because 12 and 1/4*2 is 24 and 1/2 then 9 and 2/3*2 is 19 and 1/3 and when you add that you get 43 and 5/6
First, let the number of skis rented by x and the number of snowboards rented by y. We can then assemble the first equation from the amount of money made from the rentals.
44x + 58y = 2232
The second equation can come from the fact that 9 more skis were rented than snowboards.
y = x - 9
Therefore our system is:
44x + 58y = 2232
y = x - 9
