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.

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)

According to the question, the given data for the clearance rack is as written below:

Regular price of the clearance rack = $[tex]$ 45.99[/tex]

Sales tax = [tex]7.25[/tex] percent

As per the question, multiply the given marked percentage with the regular price to get the exact value.

Therefore, Marked price(in $) = [tex]45.99X0.35 = 16.10[/tex]

Now, subtract the calculated price from the regular price:(in $)[tex]45.99-16.10 = 29.89[/tex]

Multiply the regular price with the sales tax: [tex]29.89X0.0725 = 2.17[/tex]

Add the tax price with the calculated regular price to know the register price: [tex]29.89+2.17=32.06[/tex]

The equation of the line in standard form of (2/3)x + 3 = 6y - 15 is 2x - 18y = -54.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant.

Given the equation (2/3)x + 3 = 6y - 15, to write the equation in standard form, arrange the variable(s) in one side and the constant(s) in the other.

(2/3)x + 3 = 6y - 15

(2/3)x - 6y = -15 - 3

(2/3)x - 6y = -18

Multiplying both sides by 3 to have integer coefficients.

3[(2/3)x - 6y] = 3(-18)

2x - 18y = -54

Step-by-step explanation:

General form of a geometric sequence:

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:

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.

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.

Given that,

To determine the coordinate of b  if M is the midpoint of AB. A(1, -4) and M(-3 ,0).

The midpoint is that point the line whose distance from both the ends of the line is equal.

Here,

We have given two coordinates one of the endpoints of AB and the other is midpoint M i.e. A(1, -4) and M(-3, 0).

Definition of midpoint says,

x = [x₁ +  x₂] / 2 ; y = [y₁ + y₂] / 2

x₁ = 1, x = -3 , y₁ = -4, y = 0

now,

-3 = [1 + x₂] / 2 ; 0 = [-4 + y₂] / 2

x₂ = -6 - 1 ; y₂ = 0 + 4

2x - 3 ≤ 7 and 2x - 3 ≥ -7

Add 3 to both sides of the inequalities

2x ≤ 10 and 2x ≥ -4
