what are the solutions to the following system of equations?x y = 3y = x2 − 9 (3, 0) and (1, 2) (−3, 0) and (1, 2) (3, 0) and (−4, 7) (−3, 0) and (−4, 7)
Therefore, the solutions to the given system of equations are: (2√2, -5) and (-2√2, -5).
Hence, option D (3, 0) and (−4, 7) are not solutions of the system of equations.
The given system of equations is: xy = 3.............(1)y = x² - 9..........(2) We have to solve the system of equations.
The value of y is given in the first equation. Therefore, we will substitute the value of y from equation (1) into equation (2).xy = 3x(x² - 9) = 3x³ - 27x Now, we will substitute the value of x³ as a variable t.x³ = t
Therefore, t - 27x = 3t-24x=0t = 8x Substitute t = 8x into x³ = t.
We get:x³ = 8x => x² = 8 => x = ± √8 = ± 2√2. Substitute the value of x in y = x² - 9 to get the value of y corresponding to each value of x.y = (2√2)² - 9 = -5y = (-2√2)² - 9 = -5
A system of equations refers to a set of two or more equations that are to be solved simultaneously. The solution to a system of equations is a set of values for the variables that satisfies all the equations in the system.

The sum of two consecutive numbers is 25. What is the largest of the consecutive numbers? Type a numerical answer in the space provided.
In a case whereby the sum of two consecutive numbers is 25 the largest of the consecutive numbers is 13.
How can the the largest of the consecutive numbers be calculated?Given that sum of two consecutive numbers is 25 , ans we were required to locatye the largest of the consecutive numbers. The we can represent the consecutive numbers as x and x+1. According to the problem, the sum of these two consecutive numbers is 25:
x + (x+1) = 25
Simplifying the left side of the equation:
2x + 1 = 25
2x = 24
Dividing both sides by 2:
x = 12
So the first consecutive number is 12. The second consecutive number is 12 + 1 = 13. Therefore, the largest of the consecutive numbers is 13.

Find a linear function h given h(-1)=-2 and h(-7)=-9 The linear function is h(x)= (Simplify your answer. Use integers or fractions for any numbers in the expression.)
h(x) = -7/6x - 25/6.
Given h(-1)=-2 and h(-7)=-9
For linear function h(x), we can use slope-intercept form which is y = mx + b, where m is the slope and b is the y-intercept.
To find m, we can use the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.
h(-1) = -2 is a point on the line, so we can write it as (-1, -2).
h(-7) = -9 is another point on the line, so we can write it as (-7, -9).
Now we can find m using these points: m = (-9 - (-2)) / (-7 - (-1)) = (-9 + 2) / (-7 + 1) = -7/6
Now we can find b using one of the points and m. Let's use (-1, -2):
y = mx + b-2 = (-7/6)(-1) + b-2 = 7/6 + b
b = -25/6
Therefore, the linear function h(x) is:h(x) = -7/6x - 25/6
We can check our answer by plugging in the two given points:
h(-1) = (-7/6)(-1) - 25/6 = -2h(-7) = (-7/6)(-7) - 25/6 = -9
The answer is h(x) = -7/6x - 25/6.

Mark can make 9 pancakes in 15 minutes, and Charlotte can make 42 pancakes in 45 minutes. Working together, how many minutes would it take to make 138 pancakes?
Answer:
60 mins
Step-by-step explanation:
15+45=60
The time needed to make 138 pancakes if both Mark and Charlotte work together is 227.142 minutes.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25.
As it is given that Mark can make 9 pancakes in 15 minutes, therefore, the number of pancakes that Mark can make in one minute,
\(\text{Number of Pancake in one minute} = \dfrac{9}{15}\)
Now, for Charlotte, it is given that he makes 42 pancakes in 45 minutes, therefore, the number of pancakes that Charlotte can make in one minute,
\(\text{Number of Pancake in one minute} = \dfrac{42}{45} = \dfrac{12}{15}\)
Further, the total pancakes that can be made in one minute,
\(\text{Total Number of Pancake in one minute} = \dfrac{9}{15} +\dfrac{12}{15} = \dfrac{21}{15}\)
As they both need to make 138 pancakes together, therefore, the time they need is,
\(\rm Time\ Needed = \dfrac{\text{Total number of pancakes}}{\text{Total number of pancakes in one minute}}\)
\(\rm Time\ Needed = \dfrac{138}{\frac{21}{15}} = \dfrac{138\times 15}{21} = 227.142\)
Hence, the time needed to make 138 pancakes if both Mark and Charlotte work together is 227.142 minutes.

a triangle has sides with lengths of 33 kilometers, 72 kilometers, and 78 kilometers. is it a right triangle?
This triangle is not a right triangle because the sum of the squares of the two smaller sides is not equal to the square of the largest side.
To determine if a triangle is a right triangle, you can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two smaller sides is equal to the square of the largest side.
In this case, we can compare the squares of the sides with lengths of 33 km and 72 km, and the square of the side with length 78 km:
33^2 + 72^2 = 5184 + 5184 = 10368
78^2 = 6084
Since 10368 is not equal to 6084, we can conclude that this triangle is not a right triangle.

the area of the room is 114 square feet. the length of the room is 9.5 feet. what is the width of the room?
Answer:
the width of the room is 12 feet
PLEASE GIVE ME BRAINLIEST! :)
Answer:
width of the room = 12 feet
Step-by-step explanation:
Area = length x width
We are given that the area of the room is 114 square feet and the length of the room is 9.5 feet.
Substituting these values into the formula, we get:
114 = 9.5 x width
To solve for the width, we can divide both sides by 9.5:
width = 114 / 9.5
Simplifying this expression, we get:
width = 12
Therefore, the width of the room is 12 feet.

Step-by-step explanation:
There are multiple ways to find the slope on a graph. You can either take two points from the line and do it the normal way (y1-y2/x1-x2), or you can look at the graph and see how much it "rises and runs" from one point to the next point. Since this is a pretty simple graph that is the method I used. Count how many units the line goes up and to the right from one point to the next, and remember the phrase "rise over run" for organizing the fraction. In this one, it rises one and runs one, so 1/1, and that's 1. I hope I could help.
a study of data compiled from emergency departments reveals that the number of hospital visits for cooking-related knife injuries significantly increases around major holidays. what do the variables examined in the study show?
The variables examined in the study show the number of hospital visits for cooking-related knife injuries and their frequency during major holidays. The data compiled from emergency departments shows that there is a significant increase in the number of hospital visits for such injuries around major holidays.
This suggests that there may be a correlation between the holidays and the use of knives in cooking, possibly due to increased meal preparation and cooking during these times. Other variables that could be examined in further studies include the types of knives and cooking equipment used, the types of foods being prepared, and the demographics of those who sustain these injuries.
Variables refer to any characteristic, quantity, or attribute that can be measured and that can fluctuate or vary. Variables are of two types:
Dependent variablesIndependent variablesAn independent variable is one that is thought to influence the dependent variable, which is the characteristic or response that is being measured.
The variables examined in the study indicate that the number of hospital visits for cooking-related knife injuries increases around major holidays. This implies that there is a direct relationship between cooking and knife injuries on major holidays. As a result, measures must be put in place to reduce the risk of knife injuries during the holidays. This includes the creation of awareness campaigns and the promotion of safety in the kitchen.

A data set will always have exactly one mode.
O True O False
False. A data set may have one mode, but it is also possible for a data set to have no mode or multiple modes.
What is the mode of data?A mode of data is defined as an observation with the highest frequency among the values that appear most frequently in the given data.
If no value is repeated, the dataset has no mode. If two or more values appear with the same maximum frequency, then the dataset has multiple modes.
For example, consider the following dataset:
1, 2, 3, 3, 4, 4, 5
In this dataset, both 3 and 4 appear twice, which means that the dataset has multiple modes.
So, in general, it is not always true that a data set will have exactly one mode. It depends on the values in the dataset and their frequencies.
Therefore, the correct answer would be option (B) False.
