The x-intercept is (9,0). Hope it help!
MN = ML because both angles are 50 degrees
X + 3 = 4X
3X = 3
X = 1
C is the answer
It will be the second one 90 :)
Answer:
Step-by-step explanation:
If the rate is x, then the rate of the return is x+25. In both trips, he has 40 miles to travel, therefore, it will take 40/x hours in the first trip and 40/x+25 for the return. As a consecuence
Also,
This means that if he starts at 30 miles per hour, it will take a bit more than 1 hour to be there: 1 hour and 20 minutes in the first trip, and a bit more than 40 minutes (40/55 hours) in the return.
The solution set is { y | y < -3 or y > 7}
