Paula charges $12 to shovel a driveway she shoveled 6 driveaways on saturday and then some more on sunday she made $144 for the weekend . how many driveways did she shovel on sunday

Hello mate!

We know that Paula charges $12 to shovel a driveway, and in Saturday she shoveled 6 driveaways, so in Saturday she wins:

$12*6 = $72

We know that she wins $144 at the weekend, so we want to know how many driveaways she shoveled in Sunday.

First, let's see how much money she did make on Sunday, this is:

$144 - $72 = $72

now, knowing that she charges $12 per driveaway, we have:

$72/$12 = 6

so she shoveled 6 driveaways in Sunday.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
