Answer:
The answer is 91
Step-by-step explanation:
We have the following equality:
Then a must satisfy that . So,
or
.
1) If a=7, then, it follows for the first equality that 56=14b. Then b=4. Finally, substituting b=4 in the first equality we obtain that -64=16-c. So, c= 80. We conclude that
.
As the problem states, we only consider values of a greater than zero. Then 91 is the only solution for .
The meaning of the y-intercept exists in the time required for the plane to cover 2,000 kilometers at a speed of 900 kilometers per hour (kph) with no wind. hours required for the plane to cover 2,000 kilometers at a speed of 900 kilometers per hour with no wind.
The time it takes the plane to travel 2,000 kilometers with the tailwind, t(x), exists determined by the function
where x exists the increase in speed when the plane travels with the wind (tailwind).
The y-intercept exists at x=0, then
hours
hours required for the plane to cover 2,000 kilometers at a speed of 900 kilometers per hour with no wind.
