Alright, so by finding a common denominator (with a bit of guess and check) we get 1/16=5/80 (since 80/16=5 and 5*1=5), 7/10=56/80, and 5/8=50/80. 
In addition, 6/5=96/80. To get this, we'd want 6 as the numerator and 5 as the denominator. Noting that we have parenthesis (meaning that (7/10 has to start with the parenthesis and 5/8) has to end it), we can also notice that (56-50)/80=6/80 and since 1/16=5/80, we can divide them to get (6/80)/(5/80)=
(6*80)/(5*80)=6/5

Answer is a. (-13, 12) b. (4, 11)

Step by step

When your rule is
(x,y) ➡️ (x -8, y +2)

a)
You take your input (-5, 10) and add your input rule to that input to get your output.

Input of x is -5, add x rule -8 = -13
Input of y is 10, add y rule +2 = 12

Your output or new coordinate is (-13, 12)

b) You take your input (12, 9) and add your input rule to that input to get your output.

Input of x is 12, add x rule -8 = 4
Input of y is 9, add y rule +2 = 11

Your output or new coordinate is ( 4, 11)

If your rule changes the process is still the same. Remember to watch adding or subtracting negatives. You can use a graph and plot your input and count out your “rule” to double check your work if you want.

svetlana [45]

Answer:

We conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.

Step-by-step explanation:

We know that the perimeter of a rectangle = 2(l+w)

i.e.

P = 2(l+w)

Here

  • 'l' is the length
  • 'w' is the width

Given that the length and width of the playground by a scale factor of 2

A scale factor of 2 means we need to multiply both length and width by 2.

i.e

P = 2× 2(l+w)

P' = 2 (2(l+w))

    = 2P      ∵ P = 2(l+w)

Therefore, we conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.
