The inequality between -4 and 6 is; -4<x<6

Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions

Let X represents the numbers between -4 and 6

X is between -4 and 6  means -4 and 6 is not included in the series of number. That is they are the boundaries

The numbers between -4 and 6 are; -3, -2, -1, 0, 1, 2, 3, 4, 5.

To find the inequality look the series of numbers. We notice that the numbers ( -3, -2, -1, ) are greater than -4  (the numbers are greater than -4 because they are nearer  to 0 on the left hand side of the number line) and the numbers (1, 2, 3, 4, and 5) are smaller than 6

Therefore, the inequality is; -4 < X < 6

The equation of the circular flower garden represented on the blueprint is (x-5)²+(y-15)² = 4

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, Fencing encloses a rectangular backyard that measures 200 feet by 600 feet. A blueprint of the backyard is drawn on the coordinate

plane so that the rectangle has vertices (0,0), (0, 30), (10, 30), and (10, 0).

A circular flower garden is dug to be exactly in the centre of the backyard, with a radius of 40 feet. This garden is represented of on the blueprint.

Since, the rectangle has vertices (0,0), (0, 30), (10, 30), and (10, 0) therefore, it will form a rectangle with width 10 units and height 30 units.

In this situation, the centre of the rectangle is at (5, 15) (Half of the width in the first coordinate and half of the height in the second one)

Since, we know that the equation of the circle is given by;

(x-a)²+(y-b)² = R²

Where, (a, b) is the centre point and R is the radius,

Therefore, the equation of the flower garden will be;

(x-5)²+(y-15)² = R²

Now, solving for R,

We know that the rectangular backyard width is 200 feet and this is represented with a rectangle in the blueprint with width 10 units

10 units = 200 ft

Therefore, 40 ft = 2 units

Therefore, The radius of 40 feet is represented with 2 units in the blueprint.

Now we replace R = 2 in the equation :

(x-5)²+(y-15)² = 2²

(x-5)²+(y-15)² = 4

Hence, the required equation is (x-5)²+(y-15)² = 4

The linear equation is Y = -55643.61069X + 112841371.95165, and

value for year 2000 is  $15,54,150.6.

When modelling the relationship between a scalar answer and one or more explanatory variables in statistics, linear regression is a linear method (also known as dependent and independent variables). Simple linear regression is used when there is only one explanatory variable, and multiple linear regression is used when there are numerous variables. As opposed to multivariate linear regression, which predicts numerous correlated dependent variables as opposed to a single scalar variable, this phrase is more specific.

Answer: It will take 3 weeks for both of us to have collected the same

Step-by-step explanation: just did this

Answer:

First equation: y = 14 + 3x

Second equation: y = 8 + 5x

Step-by-step explanation:

To model this situation, we can set up a system of two equations. The first equation will represent the number of items you have collected after a certain number of weeks, and the second equation will represent the number of items your friend has collected after the same number of weeks.

First equation: y = 14 + 3x

Second equation: y = 8 + 5x

To find the number of weeks it takes for you both to donate the same number of items, we can set the two equations equal to each other and solve for x.

14 + 3x = 8 + 5x

6x = 6

x = 1

It will take 1 week for you both to donate the same number of items. To find the total number of items each of you will have donated at that point, we can substitute 1 for x in either of the original equations and solve for y.

For example, substituting 1 for x in the first equation gives us: y = 14 + 3(1) = 14 + 3 = 17

So, after 1 week, you will have donated 17 items, and your friend will have donated the same number of items.

The inequality that represents the case where Donna has equal or more money saved than Jason is:

$600 + $90*m ≤ $300 + $120*m

We know that Jason has $600 on his bank, and he saves $90 per month, then the amount that he has after m months is:

J(m) = $600 + $90*m

Donna has $300 in her bank and she saves $120 each month, so after m months, she has:

D(m) = $300 + $120*m

Now we can write the inequality:

J(m) ≤ D(m)

The value is x=9, when the points are (x,1), (-3,7), (-5,9), (5,4).

The slope formula is defined as the formula used to calculate the steepness of a line and to determine how much it's inclined. To calculate the slope of the lines, we need the x and y coordinates of the points.

The formula to calculate slope is given as,

m = (y2 - y1)/(x2 - x1)

where m is the slope of the line,

x1, x2 are the coordinates of the x-axis,

y1 and y2 are the coordinates of the y-axis.

Consider the Points as A=(x,1),B=(-3,7),C=(-5,9),D=(5,4)

Now, take two points  C, D to know the m value:

Slope  = y₂ - y₁/ x₂-x₁

m1 = 4 - 9 / 5- [-5]

     = -5 / 5+5  = -5/10 = -1/2

m1 = -1/2

Consider the next two points A, B:

A(x, 1), B(-3,7)

Slope of AB m2 =  7- 1 / -3 - x  

m2= 6/-3-x

As AB  || CD, m2 = m1

6/-3-x=-1/2

The measures of the angles of the triangles are

m∠1 = 55°

m∠2 = 125°

m∠3 = 35°

What is a Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

Given data ,

Let the first triangle be represented as ΔABC

Let the second triangle be represented as ΔCDE

And ∠BAC = m∠1

And , ∠CDE = m∠3

Now , from the triangle ΔABC

∠ABC = 180° - 110° ( Angle of a straight line is 180° )

So , the measure of angle ∠ABC = 70°

The sides of the triangle AC and BC are similar

So , The angles of the triangle are = 70° + x + x = 180°

On simplifying the equation , we get

70° + m∠1 + m∠1 = 180°

Subtracting 70° on both sides of the equation , we get

2m∠1 = 110°

Divide by 2 on both sides of the equation , we get

m∠1 = 55° = ∠ACB

And , ∠ACB and m∠2 are on a straight line

So , m∠2 = 180° - 55°

On simplifying the equation , we get

m∠2 = 125°

The triangle ΔCDE is a right triangle with ∠DCE = m∠1 ( vertically opposite angles )

So , the angles of the triangle are = 90° + 55° + m∠3 = 180°

On simplifying the equation , we get

145° + m∠3 = 180°

Subtracting 145° on both sides of the equation , we get

m∠3 = 35°

Hence , the measures of the angles of the triangles are are m∠1 = 55° , m∠2 = 125° , m∠3 = 35°

A basket containing 180 cherries is split amount 3 different people. Charlie receives twice the amount that Sam receives, and Fred receives 20 more than Sam.

Let the number of cherries that Sam has be 'x'. Then the equation is given as,

x + 2x + x + 20 = 180

Simplify the equation, then we have

x + 2x + x + 20 = 180

4x = 160

x = 40

Then the number of cherries Charlie has is given as,

2x = 2(40)

2x = 80

Then the number of cherries Fred has is given as,

x + 20 = 40 + 20

x + 20 = 60
