Point M( -3, -2) is rotated 270° counterclockwise and then reflected over the x-axis. What are the coordinates of M'?

Rotation involves moving a point around a center

The coordinates of M" are (-2,-3)

The pre-image M is given as:

M =(-3,-2)

The rule of 270 degrees counterclockwise rotation is:

So, we have:

M' = (-2,3)

The rule of reflection over the x-axis is:

So, we have:

M" = (-2,-3)

Hence, the coordinates of M" are (-2,-3)

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

The solution is given in the image below

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
