Answer:
Step-by-step explanation:
Answer:
15x + 10x less than it equal to 499
Step-by-step explanation:
We have to assume that the speed before being stuck was sufficient to get to the destination on time had there been no delay. Call that speed "s" in km/h.
Since 200 km is "halfway", the total distance must be 400 km.
time = distance / speed
total time = (time for first half) + (delay) + (time for second half)
400/s = 200/s + 1 + 200/(s+10) . . . .times are in hours, distances in km
200/s = 1 + 200/(s+10) . . . . . . . . . . subtract 200/s
200(s+10) = s(s+10) +200s . . . . . . .multiply by s(s+10)
0 = s² +10s - 2000 . . . . . . . . . . . . . .subtract the left side
(s+50)(s-40) = 0
Solutions are s = -50, s = 40
The speed of the bus before the traffic holdup was 40 km/h.
Answer:
y = 6
Step-by-step explanation:
[] We can plug in our x value of -3, from the coordinate point, and solve for y.
y = 3 - x
y = 3 - (-3)
y = 3 + 3
y = 6
[] We can also graph the equation, and find the point where x = -3
