The numbers 7 in the domain and 10 in the range don't belong there.
Describe the domain and range of a function.The domain is the set of values over which the provided function is defined. The range is the set of all values that the function that is provided can return.
How are intervals in numbers understood?[a,b] refers to all values between a and b as well as a and b themselves.
With the exception of b, all values between a and b are referred to as (a,b).
We cannot write about them since we cannot include infinity or negative infinity since they are symbols for arbitrary enormous or tiny numbers, respectively.
Another thing to keep in mind is that when we plot functions, the inputs are typically on the x-axis and the outputs are typically on the vertical axis (y-axis).
Given : (2,7). (8, 12). (5,9). (10.15)
Domain: The initial value of numbers will always apply; 2, 8, 5, 10
Range: Numbers will always have a second value; 7, 12, 9, 15.
What you have here is :
Domain: (2,5, 7, 8, 10)
Range: (7.9. 10. 12. 15)
The problem is that 10 is in the range but 7 is in the domain. They shouldn't be there, those two. There is also an additional number there that you have. Only 4 digits should be in the Domain and Range. Given that there are four sets or pairs of values.

Answers
The inequality to represent the given situation is 2s+12a≤50.
Given that, it costs $2 to download a song and $12 to download an entire album.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

2) A recycling center was offering cash for different types of recyclables. For each pound of
paper recycled they offered $0.03, for each pound of aluminum they offered $1.32 and for
each pound of plastic they offered $0.07. Jerry took in 10 pounds of paper, 8 pounds of
aluminum and 7 pounds of plastic. How much money did he earn?
Answers
The money earned by Jerry at the recycling center is $11.35.
According to the question,
We have the following information:
For each pound of paper recycled they offered $0.03, for each pound of aluminum they offered $1.32 and for each pound of plastic they offered $0.07. Jerry took in 10 pounds of paper, 8 pounds of aluminum and 7 pounds of plastic.
Now, we have the following expression when multiplied with the cost of each pound:
10*0.03+8*1.32+7*0.07
Now, we will first use multiplication and then we will use addition:
0.3+10.56+0.49
$11.35
Hence, the money earned by Jerry at the recycling center is $11.35.

Nishnat can trade box tops only for printer.
Nishant keeps the box tops in 38 folders.
Each folder contains 80 box tops.
Number of box tops nishant has = number of folders x number of box tops in each folder
Number of box tops nishant has = 38 x 80
Number of box tops nishant has = 3040
For printer, he needs 1500 box tops
1500 < 3040
So, he can trade box tops for a printer.
For digital camera, he needs 3500 box tops
3500 > 3040
So, he can not trade box tops for a digital camera.

Step-by-step explanation:
y = 1/4 is the equation of a horizontal line parallel to the x- axis.
A line perpendicular to it will be a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.

6x+1.6=58
i dont know the answer to this
Answers
The value of x in the given equation, 6x + 1.6 = 58, is x = 9.4
Determining the value of x in an equationFrom the question, we are to determine the value of x in the given equation.
The given equation is
6x + 1.6 = 58
To determine the value of x in the equation, we will determine the value of the unknown variable.
The unknown variable in the given equation is x.
Thus, we will determine the value of x.
Solving the equation for x
6x + 1.6 = 58
Subtract 1.6 from both sides of the equation
6x + 1.6 - 1.6 = 58 - 1.6
6x = 56.4
Divide both sides of the equation by 6
6x/6 = 56.4/6
x = 9.4
Hence, the equation solved for x gives x = 9.4

Answer:
x = 23
y = 119
Step-by-step explanation:
Line m is parallel to line n and the angle given as 61 and the angle that is represented with 4x - 31 are alternate angles and have equal measurement.
We can write the following equation based on this information:
4x - 31 = 61 add 31 to both sides
4x = 92 divide both sides by 4
x = 23
now onto y,
the angle represented with y and the angle that is represented with 4x - 31 are supplementary and their measures add up to 180:
4x - 31 + y = 180 replace x with 23
4*23 - 31 + y = 180
92 - 31 + y = 180 subtract like terms
61 + y = 180 subtract 61 from both sides
y = 119

4π/5 and -16π/5 are Coterminal angles with -6π/5
What is Angle?an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle
Coterminal angles are angles that share the same initial and terminal sides. To find an angle coterminal to another you can do so by simply adding or subtracting any multiple of 360 degrees or 2 pi radians.
The given angle is -6π/5
We need to add 2π for finding coterminal angle
-6π/5+2π

In which the coordinates of the vertex are (h,k), representing the turning point of the graph of the absolute value function, the point in which the function makes the "V".
In this problem, the definition of the function is:
y = 2|x + 2| - 6.
Hence the coordinates of the vertex are:

A scale factor is a measure of similar figures that look the same but have different scales or measurements. Suppose two circles are similar but may have different radii. The scale factor indicates how much larger or smaller the figure is than the original figure. Scale allows you to scale the original shape up or down and draw it. The amount by which a shape is magnified or shrunk is called the scale factor. Used when you need to increase the size of 2D shapes such as circles, triangles, squares, and rectangles. Magnification is also well understood from the basic theorem of proportionality.Calculationinitial volume = 13 cubic feet
