If the point (-1/2, y) lies on the line whose equation is 2x - 3y = 6, what is the value of y?
-7/3
-5/3
7/3

A.

Step-by-step explanation:

We have been given that the point lies on the line whose equation is . We are asked to find the value of y.

To find the value of y, we will substitute in our given equation as:

Therefore, the value of y is

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
