Answer:
g(f(x)) = x . . . so the functions are inverses
Step-by-step explanation:
Two functions f and g are inverses of each other if ...
g(f(x)) = x or f(g(x)) = x
We are asked to evaluate g(f(x)). That will be x if the functions are inverses.
g(f(x)) = g((x+1)/2) = 2((x +1)/2) -1 = (x +1) -1
g(f(x)) = x . . . . the functions are inverses
What should you do? Jason collects baseball cards. He has 33 cards. He wants to put 4 cards on each page of his book. How many pages will he need to put all of his cards in the book? Should you.. Ignore the remainder Ignore the remainder Increase the quotient by one Increase the quotient by one Remainder as the answer
Answer:
Increase the quotient by one
Step-by-step explanation:
Since in the question it is mentioned that There is a total of 33 cards and wants to put 4 cards on each page
So for determining the number of pages for put all of his cards
We should do increment in the quotient by 1 as there is a requirement of an additional page for the left cards
Therefore the above is the answer
What is the y-intercept of the line
(0, -5)
Solution:The y-intercept of the line is the point where the line intersects the y-axis.The y-intercept is written like this: (0, b) where "b" stands for the y-intercept of the line.The line touches the y-axis (the vertical axis) at (0, -5)Therefore, the y-intercept of the line is (0, -5) or -5.Hope it helps.

In November 2010 the average cost of 5 gallons of regular unleaded gasoline in the United States was $14.46. What was the average cost for 16 gallons of gasoline?
Answer:
$46.72
Step-by-step explanation:
The first step is to find the price of 1 gallon
5 gallons= 14.46
1 gallon= x
5x= 14.46
x= 14.46/5
1 gallon= $2.92
Therefore the cost of 16 gallons of gasoline can be calculated as follows
1 gallon= 2.92
16= x
x= 2.92 × 16
= $46.72

What is the inverse of the function f(x) = 1/4x - 12?
Oh(x) = 48x - 4
Oh(x) = 48x + 4
O h(x) = 4x - 48
O h(x) = 4x + 48
Happy Holidays! :)
[tex]\large\boxed{h(x) = 4x + 48}[/tex]
[tex]f(x) = \frac{1}{4}x - 12[/tex]
Find the inverse. Begin by swapping the x and y (f(x)) variables:
[tex]x= \frac{1}{4}y - 12[/tex]
Begin isolating for y. Add 12 to both sides:
[tex]x + 12 = \frac{1}{4}y[/tex]
Multiply both sides by 4:
[tex]4(x + 12) = \frac{1}{4}y * 4[/tex]
[tex]4x + 48 = y[/tex]
Therefore:
[tex]h(x) = 4x + 48[/tex]

❀ Explanation :
✑ Let's Know about A.M ( Arithmetic Mean )
In statistics , a single number can be calculated from a group of data which shows the character of the whole data. This number is called the average of the while data. An average is also called the arithmethic mean or simply mean which is a measure of central tendency.
☄ To calculate the average of the given type of data ( discrete series ) , follow the steps given below :
Make the table of 3 columns .Write down the items or observations ( x ) in the first column in ascending order and the corresponding frequency ( f ) in the second column.Multiply the data ( x ) by their corresponding frequency ( f ) and write down the product in third column of fx.Find the sum of f - column and fx - column separately.Divide the sum of fx by the sum of f , the quotient so obtained is the required mean.✐ Remember :
[tex] \underline{ \boxed{ \sf{mean \: = \frac{Σfx}{Σf} \: or \: \frac{Σfx}{n}}}} [/tex]
Where , Σf = N = Sum of the frequency and the symbol ' Σ ' ( sigma ) means " summation of " .

Ibrahim has two lists of numbers. The mean of the numbers in the first list is p. The mean of the numbers in the second list is q. Ibrahim combines the two lists into one new list of numbers. Ibrahim says ‘The mean of the new list of numbers is equal to (p+q)/2 .' One of two conditions must be satisfied for Ibrahim to be correct. (b) Write down each of these conditions.
Step-by-step explanation:
The two conditions that must be satisfied for Ibrahim to be correct are:
1. The range of numbers in each list must also be the same.
2. The number of numbers in both list must also be same.

Step-by-step explanation:
3x-5y =13......eq(1)
x+4y=10....eq (2)
multiply the eq 2 with 3
then it becomes,
3x+12y=30
Subtracting eq2 from eq 1
3x-3x-5y-12y=13-30
-17y=-27
y=1.588
x+6.352=10
x=3.648

The kinetic energy of a body of mass 2 kg is 25 J. Its speed is??
Step-by-step explanation:
Kinetic Energy (K. E) = 25 J
Mass ( m) = 2 kg
Velocity or speed (v) = ?
We have the formula that
[tex]ke \: = \frac{1}{2} m {v}^{2} \\ or \: 25 = \frac{1}{2} \times 2 \times {v}^{2} \\ or \: 25 = {v}^{2} \\ or \: {5}^{2} = {v}^{2} \\ therefore \: v \: = 5 \: m |s[/tex]
it's speed is 5 m/s .
Hope it helps. :)
The speed of the body is 5 m/s
Applying the formular of kinetic energy
Kinetic energy: This can be defined as the energy posses by a moving body or that depends on the speed of a body.
The formular for kinetic energy is
E = mv²/2.................... Equation 1
Where E = Kinetic energy of the body, m = mass of the body, v = veocity/ speed of the body.
make v the subject of equation 1 above
v = [tex]\sqrt{2E/m}[/tex]................ Equation 2
From the question,
Given: E = 25 J, m = 2 kg
Substitute these values into equation 2
v = [tex]\sqrt{2*25/2}[/tex]
v = [tex]\sqrt{50/2}[/tex]
v = [tex]\sqrt{25}[/tex]
v = 5 m/s.
Thus, the speed of the body is 5 m/s

Andrew purchased a coat for $50.00 on sale for 25% off. What was the cost of the coat after the discount not including tax?
Answer:
$37.50
Step-by-step explanation:
Sale = $50.00 x 25% = $12.50
=> The coat after the discount = $50.00 - $12.50 = $37.50
$37.50
Step-by-step explanation:
Sale = $50.00 x 25% = $12.50

Which statement about 272° is correct?
A. tan 272° < 0
B. sin 272° > 0
C. cos 272° < 0
Answer:
tan 272 < 0 is the correct answer
Step-by-step explanation:
Firstly, we need to understand the quadrant in which we have the angle
Mathematically, angle 272 is on the 4th quadrant
On the 4th quadrant, only the cosine value is positive, sine and tangent values are negative
Hence, we have that tan 272 < 0
is the correct answer
Answer: A. tan 272° < 0
