Answer:
A and B
Step-by-step explanation:
To be inverses, the inverse composite functions must equal x, since the input and output must be equal as how much you used as your input, which is x. B proves that. Also, the graph must reflect over y = x, which is the line that runs through the origin

what is the value of v if 13v = 65
Answer:
[tex]v=5[/tex]
Explanation:
The equation is asking for multiplication (13 * v), and the opposite of multiplication is division. So if we divide 65 by 13, we find 5.
13 * 5 = 65
Answer:
v = -5
Step-by-step explanation:
1. Pull out like factors :
-13v - 65 = -13 • (v + 5)
2. Solve : -13 = 0
This equation has no solution.
A a non-zero constant never equals zero.
3. Solve : v+5 = 0
Subtract 5 from both sides of the equation :
v = -5

If AB= x+4, BC=2x-10, and AC=2x+1, then find the value for x
Answer:
[tex] \boxed{x = 7} [/tex]
Step-by-step explanation:
Given:
AB = x + 4BC = 2x – 10AC = 2x + 1We can illustrate this relationship as:
(2x + 1)
___↑___
| |
A — B — C
|____|___|
↓ ↓
(x + 4) (2x – 10)
_______________________________
When you are given an algebraic expression for the length of a segment, you can solve for that value by knowing that the sum of two segments AB + BC = AC.
Thus:
(x + 4) + (2x – 10) = (2x + 1)
[Regroup terms]
(x + 2x) + (4 – 10) = (2x + 1)
[Simplify]
(3x – 6) = (2x + 1)
[subtract 2x from both sides to isolate the variable]
(3x – 6) – 2x = (2x + 1) – 2x
[Regroup terms]
(3x – 2x) – 6 = (2x – 2x) + 1
x – 6 = 1
[Add 6 to both sides to isolate the constant]
x – 6 + 6 = 1 + 6
[Simplify]
x = 7
the distance between towns is 924 miles. On a map, this represented by a length of 7 inches. On the same map how many inches would there be between two cities 1584 miles apart.
Answer: 12 inches
Step-by-step explanation:
1: place the units in the ratios (make sure they match, you should label the numbers in your work so you know put the units in right unlike what i did in my work) and cross multiply
2: divide both sides by 924 in. to get x by itself
3. x = 12 in.

Complete the sequence given below:
2,2,5,13,28,?
Answer:
52
Step-by-step explanation:
Answer for this question as follows
2–2=0
5–2=3
13–5=8
28–13=15
As we observe the difference of the difference is
3–0=3
8–3=5
15–8=7
Here the differnce is increasing by two
X-15=7+2=9
X=24
So the required answer is 28+24=52

3.568409 rounded to the nearest hundredth
Answer:
3.57
Step - step
So the hundredth is the 6
you need to look the next number after 6
it is 8 which is more than 5 so
the hundredts number which is 6 need to plus one(+1)
3.56 + 0.01
= 3.57
and the number after seven No need to do it
