Answer:
The answer is 3x+6
Step-by-step explanation:
You multiply what's on the outside of the parenthesis by everything on the inside, so you would do 3 times x and 3 times 2. They don't combine because they are like terms.
That would be 0.14 after rounding up from 0.1379
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.
<h3>What is the meaning of the y-intercept for the function
?</h3>
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.
