Value of f(g(3)) is -22.
What is a function?Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given
f(x) = 4x – 2
g(x) = -2x + 1
Value of f(g(3))
g(x) = -2x + 1
g(3) = -2(3) + 1
g(3) = -6 + 1
g(3) = -5
f(g(3)) = f(-5)
f(x) = 4x – 2
f(-5) = 4(-5) - 2
f(g(3)) = -20 -2
f(g(3)) = -22
Hence, value of f(g(3)) is -22.

What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
108° → 12 people.
Per degree people or the ratio of degree to people will be,
1° → 12/108 people
In a circle, there is 360° thus multiply by 360 on both sides,
360° = 12/108 x 360 = 40 people
Hence "The total number of people in the pie chart will be 40.".

How many solutions will this system of equations have? y = 3.5x − 3.5 y = −3.5x + 3.5 No solution Infinite solutions One solution Two solutions\
It will not have any possible solutions
Step-by-step explanation:
this would actually have some solutions because
y=3.5x−3.5
Step: Substitute 3.5x−3.5 for y in y=−3.5x+3.5:
y=−3.5x+3.5
3.5x−3.5=−3.5x+3.5
3.5x−3.5+3.5x=−3.5x+3.5+3.5x(Add 3.5x to both sides)
7x−3.5=3.5
7x−3.5+3.5=3.5+3.5(Add 3.5 to both sides)
7x=7
7x
7
=
7
7
(Divide both sides by 7)
x=1
Step: Substitute 1 for x in y=3.5x−3.5:
y=3.5x−3.5
y=(3.5)(1)−3.5
y=0(Simplify both sides of the equation)
x=1 and y=0

Sarah is keeping up with how many miles her car gets per gallon. She starts with a full tank. After 448 miles, she fills up with 14 gallons. If she plots the points (0,0) and (14,448) on a coordinate plane, what would be the y-value of the point (1,y)?
Using a linear function, it is found that the value is: y = 32.
A linear function has the following format:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of x when y = 0.In this problem, when [tex]x = 0, y = 0[/tex], and thus, the y-intercept is [tex]b = 0[/tex].
Then
[tex]y = mx[/tex]
She also plots the point (14, 448), which means that when [tex]x = 14, y = 448[/tex], and this is used to find m.
[tex]14m = 448[/tex]
[tex]m = \frac{448}{14}[/tex]
[tex]m = 32[/tex]
Hence, the linear function is:
[tex]y = 32x[/tex]
Then, when x = 1, the point is (1,y), and:
[tex]y = 32(1) = 32[/tex]
The y-value is y = 32.

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We have been given that there are 25 students in Ms.Morris's class. She wants to divide the class into 3,4,or 5 equal teams with all students on a team.
If Ms. Morris wants to divide all the students in 3, 4 or 5 equal teams, then apply a division to know the number of students per group.
If she makes 3-students groups, it would be;
25/3
If she considers 4-students groups, then it would be;
25/4
Thus, it can be seen that she cannot divide a students in parts to have equal groups.
Therefore, she has to make 5-students groups,
25/5 = 5
This means that she can make groups of 5 students each, and she would have equal groups.

An animal shelter has 7 puppies. If the puppies are 28% of the total dog and cat population, how many dogs and cats are in the animal shelter?
The total number of dogs and cats in the animal shelter is 25. We get this by dividing the number of puppies, which represent 28% of the population, by 0.28.
Explanation:To figure out the total dog and cat population in the animal shelter, we need to use the information given to us: the puppies, which make up 28% of the total population, number 7. To get the full population, we need to think of these 7 puppies as representing 28%. The way to get the total is to divide the number of puppies by the percentage they represent. Express 28% as a decimal and divide:
7 / 0.28 = 25
So there are 25 dogs and cats in the animal shelter.

carlos has a string that is 24 inches long. he wants to divide it into 3 equal parts. write an equation to find how long each part will be. use ? to represent the unknow number. then solve your equation.
Final answer:
Carlos can divide his 24-inch string into 3 equal parts by solving the equation 3x = 24, which gives each part a length of 8 inches.
Explanation:
Carlos has a string that is 24 inches long and wants to divide it into 3 equal parts. To find how long each part will be, we can represent the unknown length of each part by the variable ? (which we will replace with x for the equation). The equation we can write for this scenario is 3x = 24.
To solve for x, we divide both sides of the equation by 3:
3x / 3 = 24 / 3x = 8So, each part of the string will be 8 inches long.

Create two whole number division problems that have a quotient of 9 and a remainder of 5. Justify which is greater using decimal division.
Answer and explanation;
If we choose two whole numbers; 8 and 10
We want to divide certain numbers by 8 and 10 to get 9 remainder 5.
In this case; 77 divided by 8 is equal to 9 rem 5
and 95 divided by 10 is equal to 9 rem 5
To justify which is greater, we use decimal division;
= 77 divided by 8 we get 9.625 ( 77 ÷ 8 = 9.625)
and
= 95 divided by 10 is equal to 9.5 (95 ÷10 = 9.5)
Therefore; the first case is greater since 9.625 is greater than 9.5
That is; 9 rem 5 got after dividing 77 by 8 is greater than 9 rem 5 got after dividing 95 by 10.
a can of juice contains 175 calories per 2.5 servings which of the following is not an equivalent number of calories per serving
To find the equivalent number of calories per serving based on that a can of juice contains 175 calories for 2.5 servings, divide 175 by 2.5 to get 70 calories per serving. Any amount other than 70 calories per serving would not be equivalent.
Explanation:The question is asking to find an equivalent number of calories per serving based on the information that a can of juice contains 175 calories per 2.5 servings. To calculate the calories per serving, we divide the total number of calories by the number of servings, so:
Calories per serving = Total calories ÷ Number of servings = 175 calories ÷ 2.5 servings = 70 calories per serving.
Now, let's say we have several options that represent the number of calories per serving:
70 calories per serving (correct equivalent)60 calories per serving (not an equivalent)75 calories per serving (not an equivalent)80 calories per serving (not an equivalent)From this list, every option except for the first one (70 calories per serving) is not an equivalent number of calories per serving as our calculated 70 calories per serving.
