i need help asap f(x) = -x - 1 determine the domain of the relation when the range is -2, 0, 2
Answer:
the domain is: {−3,0,1,6}
the range is:{2,3,4,−6,4}
the relation is not a function since it has TWO distinct y values '4' and '-6' for the same x value of '1' .
Explanation:
In the relation:
{(−3,2),(0,3),(1,4),(1,−6),(6,4)}:
The domain:
Is the set of all the first numbers of the ordered pairs.
In other words, the domain is all of the x-values.
So in this case the domain is:
{−3,0,1,6}
The range:
Is the set of the second numbers in each pair, or the y-values.
So in this case the range is:
{2,3,4,−6,4}
A relation is a function if it has only One y-value for each x-value.
So in this case the relation is not a function since it has TWO distinct y values '4' and '-6' for the same x value of '1' .

if the mean is 9,8,10,x,14 is 11 then find the value of x
The value of x is 14
In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply put, the mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally. The three most frequently employed measures of central tendency are the mean, median, and mode. The total values provided in a datasheet must be added, and the sum must be divided by the total number of values in order to determine the mean. When all of the values are organised in ascending order, the Median is the median value of the given data. While the number in the list that is repeated a maximum of times is the mode.
To find the mean, add up all the numbers and then divide by the number of numbers

each of two persons tosses three gair coincs. what is the probability that they obtain the same numbre of heads
The probability of getting three heads when tossing three coins is 1/2 x 1/2 x 1/2 = 1/8.
1/8
The probability of getting a head or a tail when flipping a coin is 1/2.
Therefore, the probability of getting two heads when tossing two coins is 1/2 x 1/2 = 1/4.
The probability of getting three heads when tossing three coins is 1/2 x 1/2 x 1/2 = 1/8.
Since each person is tossing three coins, the probability that they both obtain the same number of heads is 1/8.
The probability of getting n heads when tossing n coins is 1/2^n. Therefore, the probability of getting the same number of heads when two people toss n coins is 1/2^n. This means that if two people each toss a coin, the probability that they both get heads is 1/4; if they each toss two coins, the probability that they both get two heads is 1/16; if they each toss three coins, the probability that they both get three heads is 1/64; and so on.

Daniel is working two summer jobs, making $8 per hour babysitting and making $15 per hour lifeguarding. In a given week, he can work a maximum of 18 total hours and must earn no less than $200. If Daniel worked 3 hours babysitting, determine the minimum number of whole hours lifeguarding that he must work to meet his requirements
The minimum number of hours life guarding that Daniel must work to meet his requirements = 12 hours
To the nearest whole number approximately:
If the digit following the decimal is less than 5, only the number preceding the decimal should remain unchanged.
Add one to the number before the decimal and eliminate the decimal part if the digit following the decimal is five or greater.
Given the information,
Babysitting pays Daniel $8 per hour, and life guarding pays him $15 per hour.
Daniel can only work a total of 18 hours per week and must make at least $200.
Daniel has been babysitting for three hours.
Daniel thus makes 3 x 8 = 24 dollars.
He has earned $200 - 24 = 176 dollars from the original $200.
Let's say Daniel was a lifeguard for m hours.
He therefore made m x 15 = 176.
15 × m = 176
m = 11.73
m ≈ 12 hours
So, the minimum number of whole hours = 12
This means, Daniel must work 12 hours lifeguarding to meet his requirements.

A rectangular plot is 40m long and 16m broad. A road of uniform width of 2m surrounds the plot inside it. Find the cost of paving the road with bricks at Rs 15 per square metre and also find the cost of covering the remaining part of the plot with grass at Rs 9 per square metre?
PLEASE answer the question i need to know the answer please
Answer:
Step-by-step explanation:
$3120 and $3888
width of the road=2m
outer Rectangle, I = 40m, b = 16m
Inner Rectangle, I = 36m, b = 12m
Area of Outer rectangle = 40x16= 640m2
Area of inner Rectangle = 36x12= 432m2
Area of the road=640-432 =208m2
cost of paving bricks $15
=208x15 = $3120. Ans
Area of inner Rectangle 432m2
cost of covering with grass $9
= 432x9= $3888.
Answer: brick cost= 3120 grass cost =3888
Step-by-step explanation:
Calculate area of the road by subtracting the area of the inner plot (36x12) from the area of the whole plot (40x16). Multiply the individual costs by the area of their respective places.
(40x16) - (36x12) = 208
208x16 = 3120
36x12 = 432
432x9 = 3888
patricia's parents buy her too much stuff, so she had 3 times as many as her friend suzy. if patricia has 15 toy trucks, how many does suzy have?
The solution of units problem is Suzy has 5 toy trucks by using the equation 15 = 3 * Suzy's number of toy trucks
According to the given information:
If Patricia has 3 times as many toy trucks as Suzy, we can set up an equation where:
Patricia's number of toy trucks = 3 * Suzy's number of toy trucks
We know that Patricia has 15 toy trucks, so we can substitute that value into the equation:
15 = 3 * Suzy's number of toy trucks
Now we can solve for Suzy's number of toy trucks:
Suzy's number of toy trucks = 15 / 3
Suzy's number of toy trucks = 5
Therefore, Suzy has 5 toy trucks.

Sarah Meeham blends coffee for Tasti-Delight. She needs to prepare 120 pounds of blended coffee beans selling for $4. 17 per pound. She plans to do this by blending together a high-quality bean costing $5. 25 per pound and a cheaper bean at $2. 00 per pound. To the nearest pound, find how much high-quality coffee bean and how much cheaper coffee bean she should blend
Sarah should blend 80.5 pounds of the high-quality beans and 39.5 pounds of the cheaper beans to make 120 pounds of blended coffee.
In this problem, we are given that Sarah Meeham needs to prepare 120 pounds of blended coffee beans to sell at a rate of $4.17 per pound. She plans to blend two types of coffee beans: a high-quality bean costing $5.25 per pound and a cheaper bean costing $2.00 per pound.
Let x be the number of pounds of the high-quality coffee beans needed and y be the number of pounds of the cheaper coffee beans needed. Since we need 120 pounds of the blended coffee, we have:
x + y = 120
The cost of the blended coffee is $4.17 per pound. This means that the total cost of the blended coffee is:
4.17(120) = 501.6
We can also find the cost of the high-quality and cheaper beans in terms of x and y:
5.25x is the cost of the high-quality beans
2.00y is the cost of the cheaper beans
The total cost of the two types of beans is the sum of their individual costs:
5.25x + 2.00y
Since we need 120 pounds of the blended coffee, we can set up the following equation using the above expressions for total cost:
5.25x + 2.00y = 501.6
Now, we can use the system of equations consisting of x + y = 120 and 5.25x + 2.00y = 501.6 to solve for x and y. One way to do this is by substitution:
x = 120 - y (from the first equation)
5.25(120 - y) + 2.00y = 501.6 (substituting x in the second equation)
Simplifying and solving for y, we get:
630 - 5.25y + 2.00y = 501.6
3.25y = 128.4
y ≈ 39.5
Now we can use this value of y to find x:
x = 120 - y
x = 120 - 39.5
x ≈ 80.5
Therefore, Sarah needs to blend approximately 80.5 pounds of the high-quality coffee beans and 39.5 pounds of the cheaper coffee beans to make 120 pounds of blended coffee that she can sell for $4.17 per pound.

The statements that MUST be true based on the given information are:
Opposite angles of Quadrilateral C are congruent.Opposite angles of Quadrilateral L are congruent.Why are these statements true?For Quadrilateral C, if all four sides are congruent, then opposite sides are parallel and opposite angles are congruent. This can be proven using the fact that in an isosceles trapezoid (which is a special case of Quadrilateral C), opposite angles are congruent.
For Quadrilateral L, having two pairs of parallel sides and congruent diagonals means that it is a parallelogram with congruent diagonals.
