State wether each function is a linear function. write yes or no f(x) =x+12 / 5

Yes

Step-by-step explanation:

That function is linear because it doesn't involve any exponents and it follows the form of Y=mx+b where m is the slope and B is the Y intercept. In this example f(x) is Y and m is 1 and B is 12/5.

I hope this helps and please don't hesitate to ask if there is anything still unclear!

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

answer: 177/8
