Suppose that f(x) = x + 4 and g(x) = -x + 3. Find (f )(g)(4).
Answer:
-12
Step-by-step explanation:
I am assuming that you want (f*g)(4), which is the product of f and g at x = 4.
If this is actually the case, then one way to evaluate (f*g)(4) is to find f(4) and g(4) separately and then multiply the results together. This gives us
f(4)*g(4) = (8 + 4)*(-4 + 3) = -12

Multiply h by 5, then divide the product by 8.
On a family outing, Tyler bought 5 cups of hot cocoa and 4 pretzels for $18.40. Some of his family
members would like a second serving, so he went back to the same food stand and bought another 2
cups of hot cocoa and 4 pretzels for $11.20.
Here is a system of equations that represent the quantities and constraints in this situation.
5c + 4p = 18.40
2c + 4p = 11.20
1. What does the solution to the system, (c,p), represent in this situation?
2. If we add the second equation to the first equation, we have a new equation: 7c+ 8p = 29.60.
Explain why the same (c, p) pair that is a solution to the two original equations is also a solution to
this new equation.

What is Proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
From the figure we can write the true statements are
d/b = b/e

A carton has a length of 2 1/2 feet, width of 3 1/2 feet, and height of 5 feet. What is the volume of the carton?
Answer:
Volume of the carton = 43 3/4 feet ³
Step-by-step explanation:
Volume of the carton = length × width × height
length = 2 1/2 feet
width = 3 1/2 feet
height = 5 feet
Volume of the carton = length × width × height
= 2 1/2 feet × 3 1/2 feet × 5 feet
= 5/2 × 7/2 × 5
= (5*7*5) / (2*2)
= 175 / 4
= 43 3/4 feet ³
Volume of the carton = 43 3/4 feet ³

graph equation: y > 4/3x – 2
Explanation:
Since the equation of the graph represents an inequality of the line y = 4/3x – 2, where y > 4/3x – 2, the coordinates are in the form of (x, y) where x is the horizontal (left or right) position, and y is the vertical (up or down) position.

The translation is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
The dilation of the graph is with a factor of 1/3.
Option A is the correct answer.
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
Figure WXYZ is dilated to W'X'Y'Z'.
The coordinates of the figure WXYZ.
W = (-6, 0)
X = (3, 3)
Y = (6, -6)
Z = (3, -3)
The coordinates of W'X'Y'Z'.
W' = (-2, 0)
X' = (1, 1)
Y' = (2, -2)
Z' = (1, -1)
This means,
There is a dilation with a factor of 1/3.
Thus,
The dilation of the graph is with a factor of 1/3.
Option A is the correct answer.

Which function has a greater rate of change?
Given:
Graph of function 1.
The equation of function 2 is [tex]y=\dfrac{1}{2}x+7[/tex].
To find:
The function which has a greater rate of change.
Step-by-step explanation:
From the given graph it is clear that, the function 1 passes through two points (0,0) and (1,2). So, slope of function is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{2-0}{1-0}[/tex]
[tex]m=\dfrac{2}{1}[/tex]
[tex]m=2[/tex]
So, rate of change of function 1 is 2.
On comparing the equation [tex]y=\dfrac{1}{2}x+7[/tex] with [tex]y=mx+b[/tex], where m is slope and b is y-intercept, we get
[tex]m=\dfrac{1}{2}[/tex]
So, rate of change of function 2 is [tex]\dfrac{1}{2}[/tex].
Since, [tex]2>\dfrac{1}{2}[/tex], therefore, function 1 has a greater rate of change.
Solution :
Function 1 passes through (0,0) and (1,2) .
So, equation of function 1 is :
[tex]y - 0 = \dfrac{2-0}{1-0}(x-0)[/tex]
y = 2x
Function 2 is : y = 0.5x + 7
We know coefficient of x in linear equation is the slope.
Also, rate of change is directly proportional to slope.
Therefore, function 1 has a greater rate of change.
Help me find the value of x
Answer:
x = 135°
Step-by-step explanation:
this is a 6-sided polygon so to find the sum of the interior angles you use this formula: (n - 2)·180° where 'n' are the number of sides
(6 - 2)·180° = 4(180)° = 720°
2 right angles = 180°
4x + 180 = 720
4x = 540
x = 135°

2. I gathered the percents of how many people with iphones and a MP3 player, and how many without iphones have a MP3 player. About 53% of people with iphones have a MP3 player while a whopping 67% of people without iphones had a MP3 player. This helped with the correlation and can also help the gathering of data be more useful to other questions. For example, "What percentage of people have an iphone?".
