The standard form equation for a circle is
where (h, k) is the center and r is the radius.
The standard form equation for an ellipse is
(center h, k and major and minor axes a and b)
This equation is standard form for neither, but might be general form for one.
He bought 3 cucumbers because 3*5=15, 15-6=9, 9*.7=6.3, .3*3=.9, .9+6.3=7.2
The graph that represents the system of inequalities is graph 3
Answer:
The slope is m = 7/8 or 0.975
Step-by-step explanation:
The distance between Car A and car B,When Car A crosses the start line is:
distance =speed car B* time
distance=(15 m/s)(3 s)=45 m
Distance traveled by car A =x, (when the car B is at the same distance from the start line)
time of car A=t
x=10 m/st ⇒ x=10t (1)
Distance traveled by car B=x
time of car B=t-3
x=15(t-3) (2)
With the equations (1) and (2) we make a system of equations:
x=10t
x=15(t-3)
We solve this system of equations:
10t=15(t-3)
10t=15t-45
-5t=-45
t=-45 / -5
t=9
t-3=9-3=6
x=10 t=10 (9)=90
Answer: The time would be 9 seconds for Car A and 6 seconds for car B and the distance would be 90 meters.
