PLEASE HURRY! Each statement describes a transformation of the graph of y=x.
Which statement correctly describes the graph of

y= x + 7?

A. It is the graph of y= x translated 7 units up.

B. It is the graph of y= x where the slope is increased by 7.

C. It is the graph of y= x translated 7 units down.

D. It is the graph of y= x translated 7 units to the right.

A

Step-by-step explanation:

+7 means go up

if the graph was 7x, the graph enlarges by a factor of 7

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

y=mx+b

step-by-step explanation:

m slope, b y-intercept
