(PLEASE ANSWER ILL GIVE YOU 20 POINTS) Determine if the relation is a function. If the relation is a function, find the domain and range.Required to answer. Single choice.
Answers
Answers:
The relation is a function
Domain = {-2, -1, 0, 1, 2}
Range = {-2, 0, 2}
=================================================
Explanation:
The blue points shown are
(-2,-2)
(-1,0)
(0,2)
(1,0)
(2,-2)
Note how the x values do not repeat themselves. Visually this graph passes the vertical line test. It is impossible to draw a single straight vertical line through more than one blue point at a time. It tells us that any x input leads to exactly one y output.
The relation is a function
The domain is the set of x coordinates of the points
Domain = {-2, -1, 0, 1, 2}
The range is the set of y coordinates of each point
Range = {-2, 0, 2}
Toss out any duplicate items that may occur in the range.
Answer:
The relation is a function.
The domains are 2, 1, 0, -1, -2.
The ranges are -2, 0, 2, 0, -2

The surf instructor has an initial fee of $12 and charges $8 per hour for lessons, which is represented by the equation y = 8x + 12, where x is the number of hours and y is the total cost. The instructor gives 32 hours of lessons a month to Sandra and 24 hours of lessons a month to Bela. What is the total amount the instructor makes in a month?
Sandra: y = 8 (32) + 12. y = 256 + 12. y = 268. The instructor receives 268 dollars a month from Sandra.

Dividing by 2 always produces a number less than the original number
Answers
Dividing the number by 2 gives half of the number which is less than the original number.
Given that,
To specify dividing by 2 always produces a number less than the original number.
A number system is described as a technique of composing to represent digits. It is the mathematical inscription for describing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.
Dividing the number by 2 gives half of the number which is less than the original number.
Let the number be x,
Dividing the number by 2
Gives, x / 2 = 0.5 * x
Imply,
Dividing the number by 2 gives half of the number which is less than the original number.
Thus, dividing the number by 2 gives half of the number which is less than the original number.

Answers
Answer:
3 is the slope
Step-by-step explanation:
Mathematically, a linear function can be represented in the form;
y = mx + c
where m represents the slope and c is the y-intercept of the function.
In the equation given in the question above;
The slope of the equation is 3
What this means is that, the average rate of change between two points in the plot of the linear function is 3
Mathematically speaking, we mean that given two years and their corresponding average haircut prices, then the average rate of change between these two years on the plot is 3

One math student, John, can solve 6 math problems in 20 minutes while another student, Juaquine, can solve the same 6 math problems at a rate of 1 problem per 4 minutes. Who works faster?
1.John
2.Juaquine
Answers
Answer:
John
Step-by-step explanation:
6/20=0.3
1/4=0.25
Juaquine is solving problems at a faster rate as compared to John.
What is the rate?A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.
As per the question, we can compare their rates of problem-solving by calculating the number of problems they can solve per minute.
For John, this is 6 problems / 20 minutes = 0.3 problems per minute.
For Juaquine, this is 6 problems / (4 minutes/problem) = 1.5 problems per minute.
Since Juaquine can solve 1.5 problems per minute compared to John's 0.3 problems per minute, Juaquine is solving problems at a faster rate.
Hence, Juaquine works faster as compared to John.
