The range of the function f(x) = 2.250x is 22.5 <= f(x) <= 36
What is the range of a function?The range of a function is the set of output values of the graph.
This in other words mean the range of a function is the set of y values of the graph.
How to determine the range of the function?The function is given as
f(x) = 2.250x
Where there are at least 10 but no more than 16 players on the baseball team
This means that the domain of the function is
10 <= x <= 16
Substitute the domain values in the given function
So, we have
f(x) = 2.250x
f(10) = 2.250 * 10
Evaluate
f(10) = 22.5
f(x) = 2.250x
f(16) = 2.250 * 16
Evaluate
f(16) = 36
The range of the function is then represented as
f(10) <= f(x) <= f(16)
So, we have
22.5 <= f(x) <= 36
Hence, the range of the function f(x) = 2.250x is 22.5 <= f(x) <= 36

Your grandmother gives your little brother 42 coins. Some are dimes and some are
nickels, but they total to $3.00. How many dimes does your little brother have?
Taking into account the definition of a system of linear equations, you little brother has 6 dimes.
System of linear equationsA system of linear equations is a set of equations that have more than one unknown, appearing in several of the equations but necessarily in all of them. The equations relate the unknowns to each other.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. In other words, the values of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.
Amount of dimesIn this case, a system of linear equations must be proposed taking into account that:
"d" is the amount of dimes."n" is the amount of nickels.You know that:
Your grandmother gives your little brother 42 coins. Some are dimes and some are nickels, but they total to $3.00.The system of equations to be solved is
[tex]\left \{ {{d+n=42} \atop {0.1d + 0.05n=3}} \right.[/tex]
It is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, isolating the variable "n" from the first equation:
n= 42 -d
Replacing this expression in the second equation obtained:
0.1d + 0.05×(42 - d)= 3
Solving:
0.1d + 0.05×42 - 0.05d= 3
0.1d + 2.1 - 0.05d= 3
0.15d + 2.1=3
0.15d= 3 -2.1
0.15d= 0.9
d= 0.9÷0.15
d= 6
Finally, you little brother has 6 dimes.

What does the coefficient represent in this case?
the cost of her normal plan
how many gigabytes she went over
the cost for the gigabytes over her plan
The coefficient in this question represents the cost for the gigabytes over her plan.
What is the coefficient ?A coefficient is a number that is multiplied by a variable. In this question, the coefficient is 10 and the variable is x. 10 here represents the the cost for the gigabytes over her plan.
10x represents the variable cost. Variable cost is the cost that increases with the number of gigabyte used. Fixed cost is the cost that does not change with the gigabyte used. It remains constant regardless of the level of gigabyte used. Total cost is the sum of the fixed cost and the variable cost. The fixed cost is the cost of her normal plan.

The table represents a quadratic function. Write an equation of the function in
standard form.
X- -3,-2,-1,0
f(x)-2,0,2,8
The equation y=2x² +8x +8 represents the quadratic function in standard form.
Quadratic Function
The Standard form for a quadratic equation is ax²+ bx + c=0, where: a, b and c are your respective coefficients. In the quadratic function, the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.
To solve a quadratic function, you should find the discriminant: D=b²-4ac and then use this variable in the formula: [tex]x=\frac{-b \± \sqrt{D} }{2a}[/tex] .
You should replace the given values for x and y in the standard form for a quadratic equation is ax²+bx+c=0. When you use x=0, you can find the coefficient c. See below.
y = ax²+ bx + c
8 = 2*0 + b*0 +c
8 = 0 + 0 + c
c =8
Next step, you should find the coefficients a and b from the two given points.
For x =-1 and y=2 and x= -2 and y=0, you will havey = ax²+ bx + c, for (-1,2)
2 = a -b +8
y = ax²+ bx + c, for (-2,0)
0 = 4a -2b +8
Then,
a - b= -8+2
4a - 2b = -8
Here you have a linear system
a - b= -6 (1)
4a-2b = -8 (2)
For solving the linear system, first, you should multiply equation 1 by (-2) and after that sum equations 1 and 2.
Thus,
-2a +2b = +12 (1)
4a - 2b = -8 (2)
The result from sum equations 1 and 2 is
-2a +4a=4
2a=4
a=2
From equation 1 : a-b= -6, if a=2 you have:
a-b= -6
2 - b = -6
-b = -6 -2
-b = -8
b=8
Now you have all data for writing the standard for a quadratic equation: a= 2, b=8 and c=8
y=ax²=bx+c
y=2x²+8x+8

In the Inductive reasoning , if the statements are true then it does not mean that the conclusion will also be true.
In the Deductive reasoning , if the statements are true then the conclusion need to be true.
In the given question ,
We are playing a lottery and buy tickets with randomly generated numbers.
As the numbers are randomly generated we cannot conclude anything concrete/logically about the next number.
It is random that we have found the pattern and found the next number to be 20.
It is just a mere coincidence that the next number is 20 .
There is nothing Logical for the next number to be 20 as the numbers are randomly generated.
Since in this situation we have made a generalization after observing the pattern , "the next number you get should be 20" is mere generalization and thus, it represents Inductive Reasoning .
