Answer:
y=9
Step-by-step explanation:
slope is (y2-y1)/(x2-x1), so we plug in the values. (-4-y)/(0 - (-2)). so we get -4-y/2 since zero minus negative 2 is positive 2. given the slope is -13/2, -4-y must be equal to negative 13. So we set an equation of -13 = -4 - y. We add 4 to 13, and get -9 = -y. We multiply each side by a -1, and we get y equals 9.
We can check this by plugging 9 back into our original slope equation. (-4-9)/(0-(-2) which gives us -13/2.
Answer:
45 miles per hour
Step-by-step explanation:
if an ostrich can run with its maximun speed for five hours, it means it would be running 45 miles per hour for five hours, giving it the maximun miles of 225 over 5 hours
Distance covered by a car in 1 gallon = 32.6miles Distance covered by a car in 12.3gallons = 32.6*12.3 =400.98miles
255/56 = 4.55....
You can't have 0.55... buses so you round that up to 1.
Therefore 4+1 = 5 so 5 buses would be the minimum.
