An aeroplane needs to fly due east from one city to another at a speed of 400 kmh- 50 km h-wind blows constantly from the north-east. a How does the wind affect the speed of the aeroplane? b In what direction must the aeroplane head to compensate for the wind?

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

2? if not the correct answer you might need to provide more information

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
