The domain of this function is that: C. the domain is all real numbers 0 through 30.
What is a domain?A domain can be defined as the set of all real numbers for which a particular function is defined. This ultimately implies that, a domain is the set of all possible input numerical values (numbers) to a function and the domain of a graph comprises all the input numerical values which are shown on the x-axis.
How to identify the domain of this graph?The horizontal extent of a graph represents all domain values and they are read and written from smaller to larger numerical values, and from the left of a graph to the right.
By critically observing this graph of a function shown, we can reasonably infer and logically deduce the following:

SOMEONE HELP! I NEED THIS QUICKLY! WILLING TO GIVE 45 POINTS!!! At 1 P.M., the total snowfall is 2 centimeters. At 4 P.M., the total snowfall is 7 centimeters. What is the mean hourly snowfall? Write your answer in simplest form as a fraction or mixed number.
Answers
The mean hourly snowfall is (5/3) centimeters per hour, which means that each hour there are 5/3 centimeters more of snow.
What is the mean hourly snowfall?The mean hourly snowfall is given by the quotient between difference between the total snowfall at the two given times and the total time.
Here we have:
Initial snowfall = 2cm
Final snowfall = 7cm
Difference = 7cm - 2cm = 5cm
And that happens between 1 P.M. and 4 P.M., so we have 3 hours.
Then the mean hourly snowfall is:
M = 5cm/3h = (5/3) centimeters per hour.

Schools A and B are competing in an academic contest. Correct answers earn 12 points. Incorrect answers lose 3 points. In the final round, School A gives the same number of correct and incorrect answers. School B gives no incorrect answers and the same number of correct answers as School A. School A started the final round with 87 points. School B started with 45. The game ends with the two schools tied. Let x represent the number of correct answers given by School A in the final round. Write an equation that models the outcome of the contest. Then find the number of answers that each school got correct in the final round.
Answers
School A got 14 questions correct and School B got 14 questions correct.
What are the number of correct answers?The first step is to form a linear equations that represent the scores of the schools in the final round. A linear equation is an equation that has a single variable that is raised to the power of one. When graphed, a linear equation is usually a straight line.
Let x represent the number of correct and incorrect answers scored by School A
Total score at the end of the final round = beginning score + total scores of correct answers - total scores of incorrect answers
Total score at the end of the final round for School A :
87 + (12 ×x ) - (3 × x)
87 + 12x -3x
87 + 9x
Total score at the end of the final round for School B :
45 + (12 ×x )
45 + 12x
If the two schools are tied, it means that both of the above expressions would be equal
45 + 12x = 87 + 9x
12x - 9x = 87 - 45
3x = 42
x = 42 / 3

An airplane left an airport flying at 180 mi/h. A jet that flies at 330 mi/h left one hour later. The jet follows the same route as the airplane at a different altitude. How many hours will it take the jet to catch up with the airplane? How many miles will the jet have flown?
Answers
Using the distance formula, Jet will take 2.2 hours to catch up with the airplane.
We will find the solution using distance formula.
distance formula is a formula that is used to find the distance between two points. These points can be in any dimension.
d=rt where
d is distance r is rate or speed and t is time
"distance airplane traveled" = "distance jet traveled"
Let x = hours "airplane" was flying
x-1 = hours "jet" was flying
.
180x = 330(x-1)
180x = 330x - 330
180x + 330 = 330x
330 = 150x
330/150 = x
2.2 hours = x

A. How many real solutions does the system { y = x² {} y = 2x have?
Answers
The system of equations has one real solution (2,4).
What is a system of equations?Simultaneous equations or systems of equations are two or more equations in algebra that must be solved simultaneously (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a unique solution.The given system of equations is:
y = x²
y = 2x
Substitute the value of y in the second equation,
x² = 2x
x²- 2x = 0 ( Factorize it)
x(x - 2) = 0
x = 0 and x = 2
Putting the value of x in the equations to obtain the value of y,
y = x² = 0
y = 2x = 2(0) = 0
y = x² = 2² = 4
y = 2x = 2(2) = 4
Therefore the system of equations has only one real solution (2,4).

The number of wooden board bought by Madelyn = 7.
The length of all boards = 1.9 meters.
Thus, to find the length of each wooden board, simply divide the total length by the total board as each board is identical.
Each length = total length/number of boards
Each length = 1.9/7
Each length = 0.27 meter.
Thus, the length of each board bought by the Madelyn is 0.27 meters.

What do we mean by mathematical operations?A mathematical function called an operation, also known as an "operand" or "argument," transforms zero or more input values into a precisely defined output value.The quantity of operands affects the operation's arity.The operations that are most frequently studied are unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, and binary operations (i.e., operations of arity 2), such as addition and multiplication.So, because Lauren is traveling at a speed that is one kilometer per minute slower than Andrea's and vice versa, Andrea's speed is 3/4 km/min and Lauren's is 1/4 km/min.
Thus, Andrea will have biked 3/4 × 5 = 15/4 km in 5 minutes.Lauren will have to bike the following kilometers in total:
20 - 15/4 = 80/4 - 15/4 = 65/4 kmHer speed being 1/4 km/min, the amount of time passed will be:
(65/4)/(1/4) = 65Therefore, Lauren will reach Andrea after 65 minutes of biking.

Step-by-step explanation:
Hello!
According to the question we need to solve for c in the equation -49 = 2c - 29
-49 = 2c - 29
Flip the equation
2c - 29 = -49
Add 29 to both sides
2c - 29 + 29 = -49 + 29
2c = -20
Divide both sides by 2 to single out the variable
2c/2 = -20/2
