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)

Kite is 61.08 meters far from the ground.

The angle of elevation in math is "the angle formed between the horizontal line and the line of sight when an observer looks upwards is known as an angle of elevation". It is always at a height that is greater than the height of the observer.

Given,

Angle of elevation = 70°

Length of string = 65 meters

Distance between kite and ground = AC = ?

By the figure

Sin70° = AC/AB

0.9397 = AC/65

AC = 65×0.9397

AC = 61.0805 meters

Distance between kite and ground = 61.08 meters

Hence, ground and kite are 61.08 meters away from each other.

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.

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.

The answer to the query is

The following details are available to us:

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.

The 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.

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.

A straight angle is 90° since a circle has 360 equal degrees. We'll just take into account angles between 0° and 360° for the time being; however, we'll take into account angles higher than 360° and negative angles later, in the section on trigonometric functions.

Given,

the measure of arc CE = 9x + 5

measure of the arc ED = 4x + 1

measure of the arc CD = 101

Total measure of the circle is = 360

⇒ 9x + 5 + 4x + 1 + 101 = 360

⇒ 13x + 107 = 360

⇒ 13x = 360 - 107

⇒ 13x = 253

The new coordinates of the point in the transformed shape would be (-1/2x, -1/2y).

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.

The linear equation [ ( 2x PLUS y ) EQUALS 10 ] has only one solution.

A linear equation is an algebraic equation having the form y=mx+b, involving only a constant and a first-order (linear) term, where b is the y-intercept and m is the slope. Occasionally, the above is called a 'linear equation of two variables,' where x and y are the variables.

Now solve the given linear equation which is:

[ ( 2x + y ) = 10  ]

Now solve this equation in order to determine the number of solutions it has,

( 2x + y ) = 10

( 2x + (10 - 2x)) = 10

( 2x + 10 - 2x) = 10

( 2x + 10 - 2x) = 10

(10) = (10)

Since 10 = 10 is correct, therefore, the equation  ( 2x + y ) = 10 has only one solution.

Start with the compass's point on vertex L while maintaining the same distance, and then draw a curve that intersects the line connecting L and C.

Centre of dilation  of an image in mathematics refers to a change that results in an image with the same shape but a different size, either larger or smaller. A dilation can only be built with two bits of information.

An operation that moves, flips, or otherwise alters a figure to produce a new figure is called a transformation. Rigid transformations maintain size, whereas non-rigid transformations do not. A dilatation enlarges or reduces a figure while maintaining its original shape. To put it another way, the dilatation resembles the original. Every dilatation has a scale factor and a centre. The scale factor indicates how much the figure stretches or contracts, and the centre serves as the point of reference for the dilation (much like the vanishing point in a perspective drawing). A scale factor is usually identified by a label and is never zero. Additionally, the dilatation would be if the original figure were labelled, for example.
