If (k, 4) is a point
on the graph of the equation 4x + 2y=4, what is the
value of k?

Answer

k = -1

Step-by-step explanation:

First we turn the equation into y = mx+b format then we we can plug in the value y= 4 and get 4 = -2x + 2

subtract two from both sides so 2= -2x divide btoh sides by 2 and get x = -1

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: h
