What is the image point of (1,-1)(1,−1) after a translation left 4 units and down 5 units?
DENIUS [597]

Answer:

The new point would be (-3,-6)

Step-by-step explanation:

To solve this it is nice to graph the first point at (1,-1). Then move the point left 4 units, making x -3. and then 5 units down, which would make y -6.

Questions 1, 2, 3, and 4 are exercises to give you practice with
common denominators.  For each of these questions, change all
the fractions to common denominators, and the answers jump out at you.

#1).  5/12 = 25/60
         2/5  =  24/60
Make um negative, and then you'll have the answer right away.


#2).  The one that's negative is obviously the least.
Both positive ones must be bigger than the negative one.
For the positive ones:

           2/5  =  6/15
           2/3  =  10/15 .
Now it's easy.


#3).  This is tough.  The least common denominator is  2,520 !
It's probably easier to just do the divisions and get the decimals
for each fraction.

               -5/8  =  -0.625
               -7/9  =  -0.777...
               -4/5  =  -0.8
               -3/7  =  -0.428...
Now it's easy to line um up.


#4).  Sneaky one.
      Look closely at each fraction.
      B, C, and D are all less than 1, so they're not between 1 and anything more than 1.
      8/5 is the only one that's more than 1.     


#5).  A fraction is just a short way to write a division problem.
When you see a fraction, it means

               "the top number divided by the bottom number" .

When you actually do the division, the quotient you get
is the decimal form of the fraction.

To change a decimal into a percent,
move the decimal point two places that way  ==> .

The numbers in the boxes at the bottom of #5 are the correct numbers,
but they both should be negative.  (because the -3/8 is negative)
