  1. If Kayla has a red ribbon with length 25  9 m and piece of 5 7 m is cut from it and gave to Sania . Find how much long ribbon left with her?                                                                                                                                                                                                                      
  • Kayla has a ribbon of length = 25 9 m.
  • Part of ribbon give to Sania = 5 7 m.
  • So, the length of the ribbon left =25 9 m - 5 7 m = 175  63 = 130  63 m
  • So , the ribbon left with Kayla is 2.06 m .

If M is the Midpoint of AB, then solve for x find the unknown measures the given segments.
Leto [7]

Answer:

If M is midpoint of AB, then

AM=MB

4x-5= 2x+11

2x=16

x=8

AM= 4x-5

=4(8)-5

=32-5

=27

BM=2x+11

=2(8)+11

=16+11

=27

Hope it helps:-)

Helppp!! I NEED HELP PLEASE
Elodia [21]

Given:

The table of values for the function f(x).

To find:

The values f^{-1}(f(3.14)) and f(f(-7)).

Solution:

From the given table, it is clear that the function f(x) is defined as:

f(x)=\{(-14,11),(-7,-12),(-12,-5),(9,1),(10,-2),(-2,13)\}

We know that if (a,b) is in the function f(x), then (b,a) must be in the function f^{-1}(x). So, the inverse function is defined as:

f^{-1}(x)=\{(11,-14),(-12,-7),(-5,-12),(1,9),(-2,10),(13,-2)\}

And,

f^{-1}(f(a))=f^{1}(b)

f^{-1}(f(a))=a              ...(i)

Using (i), we get

f^{-1}(f(3.14))=3.14

Now,

f(f(-7))=f(-12)

f(f(-7))=5

Therefore, the required values are f^{-1}(f(3.14))=3.14 and f(f(-7))=5.
