HELP ME PLS Which set of transformations has been performed on triangle ABC to form triangle A′B′C′? (4 points)

A. Dilation by a scale factor of 4 followed by reflection about the x-axis
B. Dilation by a scale factor of 2 followed by reflection about the x-axis
C. Dilation by a scale factor of 4 followed by reflection about the y-axis
D. Dilation by a scale factor of 2 followed by reflection about the y-axis

A

Step-by-step explanation:

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

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
