Which statement about graphs and their inverse is true?
A class trip to a beach has been planned for your senior trip. The lifeguard is only on duty when the temperature is between 70 degrees and 105 degrees. There is room for 60 people on your trip. Write the constraints to represent this real-world problem, where x is the temperature and y is the number of people on your trip.
x > 70 and y 70
70 < x < 105 and 0 < y ≤ 60
Answer:
70 < x < 105 and 0 < y ≤ 60
Step-by-step explanation:
The constraints that represent this real-world problem are; 70 < x < 105 and 0 < y ≤ 60 where x is the temperature and y is the number of people on your trip.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Given:
The Range of temperature is between 70 and 105 degrees.
So, x lies between these two temperatures so x must be greater than 70 degrees but less than 105 degrees.
Therefore, x > 70and x < 105.
On combining these two inequalities we get,
70 < x < 105
Now, number of people that can come for the trip is 60.
y represents the number of people for the trip. So, y can be at most 60.
Or, y ≤ 60 must be less than or equal to 60 and is given as:
Hence, the constraints are:
70 < x < 105 and 0 < y ≤ 60
The constraints that represent this real-world problem are; 70 < x < 105 and 0 < y ≤ 60 where x is the temperature and y is the number of people on your trip.

Kennan graphed the location of several places in his town on the coordinate plane shown below. Determine if each statement about Kennan's graph is true or false. True False The library is 555 units from the yyy-axis. The school is located at (0,6)(0,6)left parenthesis, 0, comma, 6, right parenthesis.
Answer:
Concept: Graph Analysis
The library is 5 units to the left from the y-axis hence the statement is TrueThe School is not located at (0,6) it is located at (6,0) hence the statement is FalseAnswer if u know PLS
Answer: Fourth Option: |-23.6|
Reason: 15 is fifteen units away from zero. -13 is thirteen units away from zero. 20.5 is twenty point five units away from zero. And |-23.6| is twenty three point six units away from zero. Hence the last option being the furthest from zero.

How to solve this problem
Answer:
Solving the radical [tex]\pm\sqrt{-81}[/tex] we get [tex]\mathbf{\pm9 \ i}[/tex]
Step-by-step explanation:
We need to express the radical [tex]\pm\sqrt{-81}[/tex] using the imaginary unit i
Prime factors of 81 are: 3x3x3x3
and [tex]\sqrt{-1}=i[/tex]
Solving:
[tex]\pm\sqrt{-81}\\=\pm\sqrt{81}\sqrt{-1}\\=\pm\sqrt{3\times3\times3\times3}i\\ =\pm\sqrt{3^2\times3^2}i\\=\pm3\times3\ i\\=\pm9 \ i[/tex]
So, Solving the radical [tex]\pm\sqrt{-81}[/tex] we get [tex]\mathbf{\pm9 \ i}[/tex]

pleas give me a brainliest if this helped
Answer:
The answer is [tex]10\frac{11}{18}[/tex]
Step-by-step explanation:
Given fractions are:
[tex]5\frac{7}{9} + 4\frac{5}{6}[/tex]
The given fractions are mixed fractions whose sum has to be found. In order to do this, the mixed fractions are first converted into proper fractions then the LCM is taken to find the sum.
So,
Converting the fractions into proper fractions
[tex]=\frac{52}{9} + \frac{29}{6}[/tex]
Taking LCM
[tex]=\frac{104+87}{18}\\=\frac{191}{18}[/tex]
Converting into mixed fraction
[tex]=10\frac{11}{18}[/tex]
Hence,
The answer is [tex]10\frac{11}{18}[/tex]

Which of the following expressions is the inverse of the function y = 3x + 4?
Answer:
Reverse the x and y:
x = 3y + 4.
Now subtract 4 from both sides:
x - 4 = 3y
Divide both sides by 3:
1/3 x - 4/3 = y
From midnight to 11:00 am, the temperature dropped 1.1°C each hour. If the temperature at 11:00 am was -16.1°C, what was the temperature at midnight?
Answer:
-41.4°C
Step-by-step explanation:
1.1 * 23 = 25.3
16.1 + 25.3 = 41.4
(I prefer working with positive numbers and just switch the sign at the end)
Hope this helped.
-Pepsi
The temperature at midnight was approximately -28.2°C, here the temperature dropped by 1.1°C each hour.
From midnight to 11:00 am, there are a total of 11 hours (since 11:00 am is 11 hours after midnight).
Given that the temperature dropped 1.1°C each hour, the total temperature drop is 1.1°C/hour × 11 hours = 12.1°C.
To find the temperature at midnight, we subtract the total temperature drop from the temperature at 11:00 am:
Temperature at midnight = Temperature at 11:00 am - Total temperature drop
= -16.1°C - 12.1°C
= -28.2°C
Therefore, the temperature at midnight was approximately -28.2°C.

What is the value of x in the equation 0.75x+3=6(x-3)?
Answer:
x = 4
Step-by-step explanation:
Given
0.75x + 3 = 6(x - 3) ← distribute
0.75x + 3 = 6x - 18 ( subtract 0.75x from both sides )
3 = 5.25x - 18 ( add 18 to both sides )
21 = 5.25x ( divide both sides by 5.25 )
4 = x

85 64
A) According to the line of best fit, the predicted number of minutes spent with family for someone who spent 36 minutes playing video games is 81.54.
B) Is it reasonable to use this line of best fit to make the above prediction?
Answer:
81. 54
4) The estimate, a predicted time of 81.54 minutes, is both reliable and reasonable.
Step-by-step explanation:
Given that :
The equation of best fit is defined as :
ý = -0.36x + 94.5.
A.) Predicted number of minutes spent with family (y) for someone who spends 36 minutes playing games (x) will be :
x = 36
From the model :
ý = -0.36(36) + 94.5
y = - 12.96 + 94.5
y = 81.54
Hence.nunber of minutes spent with family = 81.54 minutes.
B.) The correlation Coefficient for the model is - 0.9993, which indicates a very strong negative relationship between both variables. Hence, using this fact, we can conclude that the prediction is reliable. From the data also, spending 36 minutes playing games means such individual will have more time than someone who plays games for 40 minutes, hence, the prediction is also reasonable.

A restaurant surveyed consumers to determine if they like hot or cold beverages for breakfast. 60 consumers like hot beverages, and 40 like cold beverages, and 12 neither, how many consumers were surveyed
Answer:
112
Step-by-step explanation:
You just have to add all of those numbers
60 +40 =100
100 + 12= 112.
Answer:
92 people
Step-by-step explanation:
Since there is 20 people who liked both hot and cold beverages, we can subtract from the people who like hot beverages and people who like cold beverages to find the people who ONLY like hot beverages and the people who ONLY like cold beverages.
People who only like cold beverages:
40 - 20 = 20
People who only like hot beverages:
60 - 20 = 40
Summing it all up:
40 + 20 + 20 + 12 = 92 people total
