Answer:

Step-by-step explanation:
1. rewrite the equation in standard form: 
2. find (h,k), the vertex. the vertex is 
3. find the 'focal length' of the parabola - the focal length is the distance between the vertex and the focus. from the vertex we can see that the focal length, p, = 3/2
4. Parabola is symmetric around the y-axis and so the asymptote is a line parallel to the x-axis, a distance p from the
y coordinate which is at
. Set up the equation:

5. substitute and solve:


hope this helps, ask me questions if you still don't understand.
keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

so we're really looking for the equation of a line with a slope of -2 and that passes through (1 , -1)

They need to babysit for 10 hours to have same money each day.
Step-by-step explanation:
On Thursday;
Charges = $3 per hour
Initial fee = $40
let x be the number of hours.
T(x) = 3x+40
On Friday;
Charges = $4 per hour
Initial fee = $30
F(x)= 4x+30
The cost will be same when;
T(x) = F(x)

They need to babysit for 10 hours to have same money each day.

Answer:
Divide 250 by 9.4 to get 26.6
Step-by-step explanation:
To calculate her unit rate, 1 minute, we must divide the distance travelled over 9.4 minutes by 9.4 to see how far she travelled in 1 minute.
It would take the bullet 25 seconds to travel 5,000 meters (:
