Use composition to prove that f(x) and g(x) are inverses. Check your work
F and G are inverse if both of them satisfy the condition h(x)=x. f(g(x))=g(f(x))=x, as we discovered. The argument f(x) and g(x) are inverse functions is thus established.
How do you verify that f x and G x are inverses?If f (x) and g (x) are inverse functions, it can be determined using one of two ways. For more information, see the explanation.
Explanation:
Instance 1
Inverse functions of both functions can be found using the first method.
Example.
Inverse of f (x) = x + 7 is what we're looking for.
We attempt to determine x using the equation y = x + 7.
y = x + 7
Inferring that g (x) is the inverse of f (x) from the fact that x = y 7
Finding g (x inverse )'s is now necessary.
g( x ) = x − 7
y = x − 7
x = y + 7
As a result, we discovered that f (x) is the inverse function of g (x).
f and g are equal if g is inverse of f and vice versa.
The second approach entails locating the compound functions f ( g ( x ) ) and g ( f ( x ) ). In this case, f and g are inverse if they are both h (x ) = x.
Example:
f ( g ( x ) = [ x − 7 ] + 7
G ( x ) placed as x is the expression in brackets.
f ( g ( x ) ) = x − 7 + 7 = x
g (f ( x ) = [ x + 7 ] − 7
f ( x ) inserted as x is the expression in brackets.
g ( f ( x ) ) = x + 7 − 7 = x
The equation f ( g ( x ) ) = g ( f ( x ) ) = x was what we discovered. The argument f (x) and g (x) are inverse functions is thus established.

What is the slope of the line that passes through the points M (-3, 8) and N (1, 5)?
The slope of the line that passes through M (-3, 8) and N (1, 5) is - 3 / 4.
How to find the slope of a line?The slope of a line is the change in independent variable with respect to the change in the dependent variable.
The slope of a line is rise over run.
Therefore, the slope of a line that passes through the point M (-3, 8) and N (1, 5) can be found as follows:
slope = y₂ - y₁ / x₂ - x₁
where
x₁ = - 3
x₂ = 1
y₁ = 8
y₂ = 5
Therefore,
slope = 5 - 8 / 1 + 3
slope = - 3 / 4
slope = - 3 / 4

what is an equation of the line that passes through the points (6,5) and (7,7)
Answer:
The slope of the line is m = 2.
The y-intercept is (0,7).
The equation of the line in the slope-intercept form is y = 2 x - 7.
Step-by-step explanation:
The slope of a line passing through two points \(P = \left(x_{1}, y_{1}\right)\) and \(Q = \left(x_{2}, y_{2}\right)\)
is given by \(m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }\)
We have that \(x_{1} = 6\) , \(y_{1} = 5y\) , and \(y_{2} =7.\)
Plug the given values into the formula for a slope: \(m=\frac{7-5}{7-6} =2\).
Now, the y-intercept is \(b=y_{1} -mx_{1}\) (or \(b =y_{2} -mx_{2}\), the result is the same).
\(b=5-(2)*(6)=-7\)
Finally, the equation of the line can be written in the form \(y=b+mx\):
\(y=2x-7\)
Answer:
\(\Large\boxed{\sf{y=2x-7}}\)Step-by-step explanation:
The slope formula is used to find the equation of the line that passes through the points in this problem.
SLOPE FORMULA:
\(\Longrightarrow: \sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{RISE}{RUN} }\)
y₂=7y₁=5x₂=7x₁=6\(\Longrightarrow: \sf{\dfrac{7-5}{7-6}=\dfrac{2}{1}=2 }\)
Use the slope-intercept form.
SLOPE-INTERCEPT FORM:
\(\Longrightarrow: \sf{Y=MX+B}\)
\(\Longrightarrow: \text{The M represents the "slope".}\)
\(\Longrightarrow: \text{The B represents the "y-intercept".}\)
y=2x-7Therefore, the slope is 2 and the y-intercept is 7.The correct answer is y=2x-7.I hope this helps. Let me know if you have any questions.
If triangles ABC and DEF are similar, what is y? Show your work.
The value of y is 18
What are similar triangles?Similar triangles have the same corresponding angle measures and proportional side lengths. The angles of the two triangle must be equal and it not necessary they have equal sides.
Therefore the corresponding angles of similar triangles are congruent and the ratio of corresponding sides of similar triangles are equal.
Therefore;
14/21 = 12/y
14y = 21 × 12
14y = 252
divide both sides by 14

12. Each section of the line on each side is identical (shown by the marks through each line)
This means both those angles are also the same.
6x + 1 = 9x-23
Add 23 to both sides
6x + 24 = 9x
Subtract 6x from both sides
24 = 3x
Divide both sides by 3
X = 8
13. Both angles when added together need to equal 180
5x-24 + 8x +9 = 180
Combine like terms
13x -15 = 180
Add 15 to both sides
13x = 195
Divide both sides by 13

Answer:
Perimeter:\(4x+10\) feet
Area:\(x^{2}+5x+6\) feet
Step-by-step explanation:
The perimeter is equal to 2*width +2*length. The width is x+2 and the length is x+3, therefore the perimeter is equal to 2x+4+2x+6 which equals 4x+10.
The area is equal to width*length
(x+3)(x+2)=\(x^{2}+2x+3x+6=x^{2}+5x+6\)
The formula for the volume of a pyramid is uppercase V = one-third uppercase B h Which of the following equations is equivalent to the given formula?
Step-by-step explanation:
One possible equivalent equation to the given formula is:
uppercase B = 3 uppercase V ÷ h
To see why this equation is equivalent, we can isolate uppercase B in the original formula by multiplying both sides by 3/h:
3/h * uppercase V = 3/h * (one-third uppercase B h)
Simplifying the right-hand side:
3/h * (one-third uppercase B h) = uppercase B
Substituting back in the original formula gives:
uppercase B = 3/h * uppercase V

lexi is making corn bread.
The recipe requires 2/3 cup of flour and 3 ¾ teaspoons of salt.
lexi wants to make the recipe using 1 cup of flour.
To maintain the ratio, how much salt is required when 1 cup of flour is used?
Answer:
If the original recipe requires 2/3 cup of flour and 3 ¾ teaspoons of salt, we can determine the amount of salt needed for one cup of flour using a proportion.
2/3 cup flour : 3 ¾ teaspoons salt
1 cup flour : x teaspoons salt
We can cross-multiply to get:
(2/3) * x = (3 ¾) * 1
2x/3 = 15/4
Multiplying both sides by 3/2:
x = (9/2) teaspoons of salt
Therefore, Lexi needs 9/2 or 4.5 teaspoons of salt when making corn bread with 1 cup of flour to maintain the ratio.
Assuming that heights of professional male tennis players follow a bell-shaped distribution, arrange in ascending order.

(C) II,I,III,
(D) III,I,II
(E) III,II,I
A height with a z-score of 1 is the lowest, a height with a percentile rank of 80 percent is in the middle, and a height at the third quartile Q₃ is the highest.
A bell-shaped distribution is also known as a normal distribution. It is a symmetrical distribution where the mean, median, and mode are all equal. The distribution has two tails that extend out from the mean in either direction. A height with a z-score of 1 is the lowest because a z-score of 1 is one standard deviation below the mean. A height with a percentile rank of 80 percent is in the middle because it is the 80th percentile, meaning that 80 percent of the data is lower than it. A height at the third quartile Q₃ is the highest because it is the 75th percentile, meaning that 75 percent of the data is lower than it. In ascending order, the heights arranged are III, II, and I.

Please help with the following question:
Using it's concept, the probabilities are given as follows:
a) Type A die and orange: 1/10 = 0.1.
b) Blue: 23/30
c) Type B, if blue: 8/23.
What is a probability?A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.
For item a, the probability that a type A dice is chosen is:
3/5.
As there are 5 dices, 3 of type A and 2 of type B.
The probability that a type A dice comes up orange is:
1/6.
As it has six faces, one of which is orange.
Then the probability of an orange type A dice being chosen is:
3/5 x 1/6 = 1/10 = 0.1.
For item b, the probability of blue is divided as follows:
5/6 of 3/5 -> type A.4/6 of 2/5 -> type B.Hence the probability of a blue dice is:
p = 5/6 x 3/5 + 4/6 x 2/5 = 23/30
For item c, we apply the conditional probability, hence the probability is given as follows:
p = (4/6 x 2/5)/(23/30) = (8/30)/(23/30) = 8/23.
Dividing the probabilities of type B and blue by the probability of blue.
