Answer:
I would say the first one
Step-by-step explanation:
The others don't make any sense, and that is the only one that mentions 2 x and 5 1s.
Answer: it took them 7 hours to travel 49 miles.
Step-by-step explanation:
The exploratory scouts travel 32 miles in eight hours.
Speed = distance/time
It means that the speed at which they travelled 32 miles is
32/8 = 4 miles per hour.
The next day they had traveled 49 miles so they increase the speed by 3 mph. It means that the speed at which they travelled 49 miles is
4 + 3 = 7 mph
Time = distance/speed
Therefore, the time it took them to travel the 49 miles is
49/7 = 7 hours
In the case of whole numbers, dividing 2 by itself would prove the conjecture false.
2/2 = 1
2/8 = 0.25
The x intercept(s) occur when f(x) = 0
so we have (x - 3)( x^2 - 25) = 0
So x - 3 = zero and x = therefore = 3.
The answer is the third choice 3
