After solving each system, 5x + y = 0, 5x + 2y = 30, the values of x and y are calculated to be -6 and 30 respectively.

The given equations are considered linear equations as the highest power of the variables in these equations is one.

By rearranging the first equation, the value of y can be found to be,

5x + y = 0

y = -5x

Putting the calculated value of y in the second equation,

5x + 2y = 30

5x + 2(-5x) = 30

5x - 10x = 30

-5x = 30

x = 30 / -5

x = -6

To solve for y, put x = -6  in the first equation as follows,

5x + y = 0

5(-6) + y = 0

-30 + y = 0

y = 30

Hence, the values of x and y in these systems are calculated to be -6 and 30 respectively.

The number of money farmers made by selling 5732 ducks will be $45856.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Mike sold 5,640 chickens and 5,732 ducks from his farm. He made $79,696. If he sold 5,640 chickens and 5,640 ducks, he would get $78,960.

Form two equations to get the amount:-

5640c + 5732d = 79696

5640c + 5640d = 78960

Solve both the equations by elimination method:-

5640c -5640c + 5732d - 5640d = 79696 - 78960

92d = 736

d = 736 / 92

d = $8

Total amount = $8 x 5732 = $45856

Therefore, the money farmers made by selling 5732 ducks will be $45856.

The radius of a table with a circumference of 10 feet is A. 1.6 ft .

A circle's outside boundary is called the circumference and can be measured, or calculated, by using

Circumference = 2πr

where r is the radius of circle.

Now it is given that,

Circumference of table = 10 feet

Since, Circumference = 2πr

⇒ 2πr = 10

Sum of the first give terms:  30.5

Step-by-step explanation:

General form of a geometric sequence:

 [tex]a_n=ar^{n-1}[/tex]

where:

Given terms:

To find the common ratio r, divide consecutive terms:

[tex]\implies r=\dfrac{a_5}{a_4}=\dfrac{40.5}{-13.5}=-3[/tex]

To find the first term, substitute the found value of r and one of the terms into the general formula:

[tex]\begin{aligned}\implies a_5 =a(-3)^4 & = 40.5\\81a & = 40.5\\a & = \dfrac{40.5}{81}\\a & = 0.5 \end{aligned}[/tex]

Sum of the first n terms of a geometric series:

 [tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

To find the sum of the first 5 terms of the geometric sequence, substitute n = 5 and the found values of a and r into the formula:

[tex]\begin{aligned}\implies S_5 & =\dfrac{0.5(1-(-3)^5)}{1-(-3)}\\\\& =\dfrac{0.5(1+243)}{1+3}\\\\& =\dfrac{0.5(244)}{4}\\\\& =\dfrac{122}{4}\\\\ & = 30.5\end{aligned}[/tex]

The four consecutive integers are 121, 122, 123, 124.

We have the sum of four consecutive integers equals to 490

We have to determine those integers.

An integer is a number with no decimal or fractional part. It includes negative and positive numbers, including zero.

Assume the first integer is x. Then, the other integers will be -

x + 1 , x + 2 , x + 3.

Therefore -

x + (x + 1) + (x + 2) + (x + 3) = 490

4x + 6 = 490

4x = 484

x = 121

So -

x = 121

x + 1 = 122

x + 2 = 123

x + 3 = 124

Hence, the four consecutive integers are 121, 122, 123, 124.

The equation of the line r is y = ₋(10/9)x ₊ 7.

Given, parallel lines have the same slope. Solve for the slope in the first line by converting the equation to slope intercept form

equation of line q is y = ₋10/9x ₊ 2

it's already in slope intercept form.

hence slope is:

m = (₋10/9) from the above the equation.

we know that the second line will also have a slope of ₋10/9 and we are given the point (9 , ₋3). We can setup an equation in slope intercept form and use these values to solve for the y inetrcept.

y = mx ₊ b

₋3 = ₋10/9 (9) ₊ b

₋3 = ₋10 ₊ b

b = 7

plug the y intercept back into the equation to get our final answer.

y = ₋(10/9)x ₊ 7

hence  we get the equation of the line r as y = ₋(10/9)x ₊ 7.

A specific, verifiable prediction of what the researcher(s) believe the study's results will be is known as a hypothesis (plural: hypothese). It is stated at the outset of the investigation.

Most often, this entails speculating on a potential correlation between two variables: the independent variable (what the researcher modifies) and the dependent variable (what the research measures).

Answer:

I believe 72

Step-by-step explanation:

The answer is (-3.-8)

When we rotate a point 90° counterclockwise around the origin, it's the same as rotating it 270° clockwise around the origin.

When we rotate something 270° clockwise around the origin, the original coordinates (x, y) becomes (-y, x).

Clockwise Rotations (CW) follow the path of the hands of a clock. These rotations are denoted by negative numbers. Counterclockwise Rotations (CCW) follow the path in the opposite direction of the hands of a clock. These rotations are denoted by positive numbers.

The angle of rotation between the two points or vertices is the number of central angles times the measure of a single central angle: angle of rotation =m×α = m × α .

y is 3, and -(3) is just -3, since multiplying negatives make a negative.

x just remains x, but it's in a different position.

This makes the new coordinate (-3, -8)
