Answer:

A) A 90 degree counterclockwise rotation about the origin followed by a translation 1 unit to the left

Step-by-step explanation:

The formula to do a 90 degree counterclockwise rotation is (x, y) to (y, -x) so if the ordered pair is (5, 3) and you were to rotate it counterclockwise it would be (3, -5). Once you do this to all of the values, you are one unit to the right of what you should be, so then you would have to translate it 1 to the left in order to match up both of the trapezoids.

please provider answer? A train travels 160160 km in the same time that a plane covers 720720 km. If the speed of the plane is 2
lys-0071 [83]
T=time
d=st
r=train speed
p=plane speed

<span>160=rt
</span><span>720=pt

speed of plan is 20kmph less than 5 times speed of train
p=5r-20

we notice that 160 times 4.5=720
times first equaton by 4.5

720=4.5rt
720=pt
set equal
4.5rt=pt
divide both sides by t
4.5r=p
sub </span><span>p=5r-20 for p
4.5r=5r-20
minus 4.5r from both sides
0=0.5r-20
add 20 to both sides
20=0.5r
times 2 both sides
40=r

sub back</span><span>
p=5r-20
p=5(40)-20
p=200-20
p=180

plane is 180kmph
train is 40kmph
