Question 3 - The vertices of a rectangle are A(-4,-3), B(-4,-1), C (-1, -1), and D (-1, -3). Determine the image's new points after a reflection in the x-axis.

the answer is 14ft

step-by-step explanation:

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

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

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
