How To Find Inverses:
1. First, replace f(x) with y . ...
2. Replace every x with a y and replace every y with an x .
3. Solve the equation from Step 2 for y . ...
4. Replace y with f−1(x) f − 1 ( x ) . ...
5. Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
Answer:
First option: Square
with diagonals 
and 
.
Fifth option: Segment 
is parallel to segment 
.
Step-by-step explanation:
We know that a square is quadriteral whose sides are equal.
By definition, a square has the following properties:
1) Its four sides are congruent.
2) The diagonals are congruent.
3) The angles formed by the intersection of the diagonals measure 90 degrees.
4) The opposite sides are parallel.
5) Each internal angle measures 90 degrees.
Notice in the figure that:
- The diagonals of the square are: and .
- and are opposite sides, therefore, they are parallel.
Answer:
11
Step-by-step explanation:
(8y + 5) - 2z
y = 3, z = 9
Let's plug in the given values.
(8(3) + 5) - 2(9)
First let's multiply.
(24 + 5) - 18
Now simplify within the parentheses.
29 - 18
Subtract.
11
This is your answer.
Hope this helps!
V=u + at
V - u = at divide both sides by
t
(V-u)/t =a
a = (v - u) /t
