Which of the following is a solution of the linear equation 3x 2y 5?
Answers
The general solution of the linear equation 3x + 2y = 5 is y = (-3/2)x + 5/2.
To find the solution of the linear equation 3x + 2y = 5, we can use the method of isolating one variable and then substituting that value back into the equation.
3x + 2y = 5
First we can try to isolate y:
2y = -3x + 5
then we divide by 2
y = -(3/2)x + 5/2
So one solution of the equation is (x,y) = (-(3/2)x + 5/2)
Therefore, the solution of the linear equation 3x + 2y = 5 is y = -(3/2)x + 5/2.

How do you find the exponential function of a data set?
Answers
An exponential function is a mathematical function of the form f(x) = a×bˣ, where a and b are constants and x is the input variable. To find the exponential function of a data set, you can use the method of least squares.
This method finds the best-fitting exponential function for a given set of data points by minimizing the sum of the squares of the differences between the data points and the function.
The first step in finding the exponential function of a data set is to plot the data points on a graph. Next, you need to re-arrange the exponential function into the form y = a×bˣ, where y is the dependent variable and x is the independent variable.
Then you can use the method of least squares to find the values of a and b that best fit the data. The value of a represents the y-intercept of the function, and the value of b represents the growth rate or decay rate of the function.
Once you have found the values of a and b, you can use the exponential function to make predictions about the data set. It is also possible to use software packages like R or Python to do this process.
In conclusion, finding the exponential function of a data set involves using the method of least squares to find the best-fitting exponential function for a given set of data points.
This is typically done by plotting the data points, re-arranging the exponential function, and using the method of least squares to find the values of a and b that best fit the data. The function can then be used to make predictions about the data set.

Answers
Answer:
Katie recorded a total of 4 + 3 + 6 + 1 + 8 = 22 dogs over the first 5 days. If the same number of dogs turned up each day for the next 3 weeks, then she would have seen the same number of dogs per day for an additional 21 days (3 weeks * 7 days/week = 21 days).

Suppose a supermarket wants to sell eggs individually. Is there a price the supermarket can charge per egg that is between the prices per egg for the two different sized cartons?
Answers
The maximum price per egg that the supermarket may charge is $0.245 per egg, which is the difference between the pricing per egg for the 2 distinct cartons.
What do you meant by the term unitary method?The unitary approach involves calculating the price of a specific unit, from which we can calculate the values of the necessary number of units.The answer to the query is
The following details are available to us:
A carton of 12 eggs costs $3.00.18 eggs in such a different carton cost $4.32.We'll first calculate the cost per egg for each of the two different-sized cartons in order to determine the cost per egg that lies between the two costs.
We are aware that the cost of one product is determined by dividing the total cost by the quantity of products.
12 eggs cost in a carton = $3.001 eggs cost = $ (3.00/12) = $0.2412 eggs cost in a second carton = $4.321 eggs cost = $(4.32/18) = $0.24The price of an egg between 0.24 as well as 0.25 must now be determined.
Note that there is a 0.01 difference between the two fees.
To precisely determine the middle charge, we will split it by two:
0.01/2 = 0.005
This can be added to $0.24 or subtracted from $0.25.
$0.24 + $0.005 = $0.245
So, $0.245 is the maximum price the supermarket can charge per egg.

Answers
The number of small sized bowls on the counter = 68 bowls
The number of medium sized bowls on the counter = 82 bowls
What is an equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
From the data given,
Let the number of small bowls on the counter be = x
Let the number of medium bowls on the counter be = y
The total number of bowls is = 150
So , the equation will be
x + y = 150 be equation (1)
The amount the small bowl can hold = 4 ounces
The amount the medium bowl can hold = 6 ounces
The total amount of all the bowls on the counter = 764 ounces
So , the equation will be
4x + 6y = 764 be equation (2)
Now , on simplifying the equation (1) and equation (2) ,
Multiply equation (1) by 4 , we get
4x + 4y = 600 be equation (3)
Subtracting equation (3) from equation (2) , we get
2y = 164
Divide by 2 on both sides , we get
y = 82
Therefore the number of medium sized bowl is 82 bowls
Substituting the value of y in equation (1) , we get
x + y = 150
x + 82 = 150
Subtracting 82 on both sides , we get
x = 68
Therefore , the number of small sized bowl is 68 bowls
Hence,
The number of small sized bowls on the counter = 68 bowls
The number of medium sized bowls on the counter = 82 bowls

What are types of exponents?
Answers
Exponents can be classified into four types: integer, rational, irrational, and complex exponents. They represent repeated multiplication, roots, and advanced concepts such as complex numbers.
Integer exponents are the most common type of exponents and include positive integers, negative integers, and zero. They are used to represent repeated multiplication, for example, 2^3 represents 2 multiplied by itself 3 times.Rational exponents are the exponents which can be written in the form of a fraction, for example, (2^(1/3)) represent the cube root of 2.Irrational exponents, as the name implies, are exponents that are irrational numbers, for example, 2^(1.23).Complex exponents are the exponents which are complex numbers, for example, 2^(3+4i). These exponents are less common and typically seen in advanced math and engineering.Learn more about Types of Exponents here:

Therefore ,the area of the rectangle will be A = 121 cm square after answering the offered question.
Rectangle: What is it?In Euclidean plane geometry, a rectangle is a polygon with four right angles. It might also be explained as follows: an equiangular quadrilateral is one in which all of its degrees are equal. Another possibility for the parallelogram is a straight angle. Four of the sides of a square are of identical length. Four 90 ° apex and equal adjacent sides make up a rectangle-shaped quadrilateral. This leads to the term "equirectangular rectangle" occasionally being used to describe it. A rectangle is also referred to as a parallelogram due to the equal and parallel lengths of its opposite sides.
Here,
Given : we have been given,
B is 11 cm long and L is 11 cm.
A = L X B = 11 X 11 = 121 cm sq, thus.
Therefore ,the area of the rectangles will be A = 121 cm square after answering the offered question.

whats the intercepts of 2x+y=1 and x-2y=8
Answers
Answer:
Step-by-step explanation:
I will assume you want the y-axis intercepts
arrange each equation into the form y = mx + b <==b is y-axis intercept
2x+y =1
y = -2x+1 <==== y axis intercept = 1
x -2y = 8
2y = x-8
y = 1/2x -4 <==== - 4 is the y axis intercept
Another way to find the y-axis intercept is to realize this occurs when x = 0
put x = 0 into the equations to find the intercept value
2x+y =1
2(0) + y = 1
y =1 <=====intercept
x-2y = 8
0 - 2y = 8
y = -4 <=====intercept
To find the where the two lines intersect, equate them
-2x+1 = 1/2x-4
5 = 2.5x
x = 2 then y = -2x+1 = -3 point of intersection (2,-3)

enlarge shape q by a scale factor of -1/2 around the centre point (0,0
Answers
The new coordinates of the point in the transformed shape would be (-1/2x, -1/2y).
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
A scale factor of -1/2 around the center point (0,0) would reflect the shape across the origin and also shrink it by a factor of 1/2.
The transformation can be represented by the matrix:
[-1/2 0]
[ 0 -1/2]
This matrix would be applied to the coordinates of each point in the shape to obtain the new coordinates of the transformed shape.
So, if a point in the shape had coordinates (x, y), the new coordinates of the point in the transformed shape would be (-1/2x, -1/2y).
