2. Determine whether the two functions are inverses.
f (x) = 1/2 x-3
g(x)= 2x+6
please help
Answer:
The two functions are inverses.
Step-by-step explanation:
Recall what an inverse is:
When you inverse an equation, like y = 2x for example, you switch, the y and x values. So you'd now have x = 2y, then x/2 = y.
In a case like that we'd say that, y = 2x, and y = x/2 are inverses of each other.
Now looking at your question, all we'd need to do is take the inverse of 1, and see if it matches up with the other one. So pick a function. I'll choose g(x) and I'll inverse it.
[tex]g(x) = y = 2x + 6[/tex]
get rid of the g(x), as it doesn't help you anymore.
[tex]y = 2x + 6[/tex]
then, switch the x and the y.
[tex]x = 2y + 6[/tex]
then isolate for y.
[tex]x - 6 = 2y[/tex]
[tex]\frac{x-6}{2} = y[/tex]
Now let's see, does [tex]f(x) = \frac{1}{2}x - 3[/tex] equal [tex]\frac{x-6}{2}[/tex] ? Well actually yes.
We just didn't simplify all the way.
[tex]\frac{x-6}{2} = y\\[/tex]
divide each term by 2
[tex]\frac{x}{2} - 3 = y[/tex]
[tex]\frac{x}{2}[/tex] can be written as [tex]\frac{1}{2}x[/tex] so we get
[tex]\frac{1}{2}x - 3[/tex] which is equal to f(x)
Therefore the 2 functions are inverses.

d = 2r
d = 22
A triangle has two sides of length 19 and 15. What is the largest possible whole-number length for the third side?
Answer: 33
To maximize the length of the third side, which I'll call x, it needs to be the longest side.
So by the triangle inequality theorem, 19+15>x, meaning the maximum whole number value of x is 33.

Miranda is calculating her expected expenses for her week long trip to Turkey. Her flight costs 928 TL (Turkish Lira), her lodging costs 755 TL, and she has allowed 814 TL for food and spending money. What is Miranda’s total? a. 4,762 TL b. 2,497 TL c. 869 TL d. 641 TL.
The addition is the process of adding two numbers and the result is the combined value of the two numbers. Miranda's total will be equal to 2497 Turkish lira.
What is Addition?Addition can be defined as the process of adding two numbers such that the result is the combined value of the two numbers.
The total cost will involve the cost of Miranda's flight, her lodging costs, and the cost of food and other such spending. Therefore, her total is the sum of all of these expenses,
Miranda's Total
= cost of flight + lodging costs + cost of food and other spending
= 928 ti + 755 ti + 814 ti
= 2497 ti
Hence, Miranda's total will be equal to 2497 Turkish lira.

what value can replace the question mark to make the statment true? 3 2/8 + ? = 7 1/8
Hello!
Question:what value can replace the question mark to make the statement true? 3 2/8 + ? = 7 1/8
Answer:
[tex]3\frac{7}{8}[/tex] Option B.
Step-by-step explanation:
Rewriting our equation with parts separated
[tex]= 7+\frac{1}{8}-3-\frac{2}{8}[/tex]
Solving the whole number parts
[tex]7-3=4[/tex]
Solving the fraction parts
[tex]\frac{1}{8} -\frac{2}{8} =-\frac{1}{8}[/tex]
Combining the whole and fraction parts
[tex]4-\frac{1}{8} =3\frac{7}{8}[/tex]
Therefore, the answer is 3 and 7/8
Hope this helps!
If you have any questions please ask!
Hey there!
3 2/8 + x = 7 1/8
13/4 + x = 57/8
x + 13/4 = 57/8
SUBTRACT 13/4 to BOTH SIDES
x + 13/4 - 13/4 = 57/8 - 13/4
SIMPLIFY IT!
x = 27/8
x = 3 7/8
Therefore, your answer is: x = 3 7/8

Please Help! If the triangle above is reflected over the y-axis, what is the correct coordinate for A'?
Answer:
A'(2,5)
Step-by-step explanation:
The position of point A is at (-2,5), and when you reflect it over the y-axis, you just have to switch the signs of the x-coordinate value.
Answer:
A'(2, 5)
Step-by-step explanation:
If the triangle is reflected over y-axis, the y-axis will be a symmetry line then the distance between A and y will remain the same but opposite sign which is 2 units ( -2 become 2 )

The prime factorization of 100 is 4x25. Show a factor tree!
Answer:
See details below:
Step-by-step explanation:
We can start with the biggest factors and work our way down to see how arrive at 4 * 25.
In this case, the first part of the tree would be 50 * 2.
2 is prime, but 50 is not and thus must be factored.
Two possible factors of 50 are 2 and 25.
The 25 is not a prime number and must be factored further.
Two possible factors of 25 are 5 and 5.
Thus, the prime factorization of 100 is 2*2*5*5.
Then to simplify, we can combine the similar factors: (2*2) * (5*5) = 4*25

==========================================================
Explanation:
The full circle has a circumference of
C = 2*pi*r
C = 2*3.14*4
C = 25.12
Divide this by four because we only want a quarter circle (and not the whole thing). Imagine cutting a pizza into four equal slices, and we only focus on one slice.
The curved portion of the slice is roughly 25.12/4 = 6.28 units long.
Add on the two straight line portions of the quarter circle to get 6.28+4+4 = 14.28
The straight line portions are the radius.
The answer of 14.28 is approximate because pi = 3.14 is approximate.
