Infinite amount of solutions

Step-by-step explanation:

This is because 3(x+5) = 3x+15

so then it would be 3x+15=3x+15

Any number in the X place would make this statement true

Infinitely Many solutions

Step-by-step explanation:

you distribute the 3 to ‘x’ and ‘15’ getting 3x + 15 on the right side. All together the equation is:

3x + 15 = 3x + 15

so no matter what number you decided to add, it’ll be the same answer, therefore making it infinitely solutions.

the answer to the question is a  

it has the same slope and the same y-intercept.

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
