The equation of the line passing through P(0, 0) perpendicular to y = -9x - 1 will be  [tex]y = \frac{1}{9}x[/tex]

The given question states that the line passes through the point P(0, 0) perpendicular to the line y = -9x - 1. We have to find out the equation of the line. We have to find the equation in slope-intercept form.

We know the slope intercept is: y = mx + b

Also, given the perpendicular line has slope m₂ = -9 according to slope-intercept form. And we know that perpendicular lines have a slope that is equal to the negative reciprocal.

So, the Slope of the line m₁ = Negative reciprocal of the slope of the perpendicular line.

=>  [tex]m_{1} = -\frac{1}{m_{2} }[/tex]

=> [tex]m_{1} = -\frac{1}{(-9)}[/tex]

=> [tex]m_{1} = \frac{1}{9 }[/tex]

We get the slope [tex]m_{1} = \frac{1}{9 }[/tex]. Also, it is given that the line passes through (0, 0) so the y-intercept b = 0. Putting these values in slope-intercept form, we get:

=> y = mx + b

=> [tex]y = \frac{1}{9} x[/tex]

Hence, the equation of the line is [tex]y = \frac{1}{9} x[/tex]

The most appropriate choice for  linear equation will be given by -

8x - (x - 35) = 2x - (7 + x) is the required equation with x = -7

What is  linear equation?

At first it is important to know about algebraic expression

Algebraic expression consist of numbers and variables connected with addition, subtraction, multiplication and division.

Equation shows the equality between two algebraic expressions by connecting the two algerbraic expressions by an equal to sign.

A one degree equation is known as linear equation.

Let y be filled in the gap

8x - (x -35) = 2x - (y + x)

8x - x + 35 = 2x - y - x

7x + 35 = x - y

putting x = -7

7(-7) + 35 = -7 -y

y = -49+35 + 7

y = 7

8x - (x - 35) = 2x - (7 + x) is the required equation with x = -7

The difference between distance around Earth's equator and distance around the Moon's equator is 284.4.

To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. We frequently employ subtraction in our daily lives. Subtraction is used, for instance, to determine how much money was spent on the products we purchased, how much money is still in our possession, or how much time is left to complete a task.

Given Data

The distance around Earth's equator is

4.00 x 104 km

= 416 km

The distance around the Moon's equator is

6.8 x 103 km

= 700.4

Difference = Distance around Earth's equator -  Distance around the Moon's equator

Difference = 700.4 - 416

Difference = 284.4

The difference between distance around Earth's equator and distance around the Moon's equator is 284.4.

Answer: Isolate the variable by dividing each side by factors that don't contain the variable.

Inequality Form:

x < 7/2

Step-by-step explanation: graph included in link

The graph which shows the solution of the inequality 4x + 2 < 2x + 9 is the graph B.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

The given linear in equality is,

4x + 2 < 2x + 9

Find the solution set of the inequality.

Operate the like terms together.

Subtracting both sides by 2x,

2x + 2 < 9

Subtracting both sides by 2,

2x < 7

Dividing both sides by 2,

x < 3.5

Hence the correct graph is B.

The measures of the angles are given as follows:

1. p = 67º.

2. q = 27º.

To solve item 1, first we have to consider that the sum of the internal angles of a triangle is of 180º, hence we find angle x, which is the interval angle of angle p.

Hence:

x + 35 + 32 = 180

x + 67 = 180

x = 113º.

An angle and it's respective external angle are supplementary, meaning that the sum of it's measures are of 180º, hence:

p + x = 180

p + 113 = 180

p = 67º.

The internal angles are given as follows:

The sum of their measures is of 180º, hence we can simply solve for q as follows:

q + 128 + 25 = 180

q + 153 = 180

q = 27º.

1. The slope is -2.

2. The slope is 1.

3. cost of 1 yards fabric is $6.49.

4. The average speed is 65 miles/ h.            

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as,

The slope of line is the measure of steepness or the direction of line the coordinate plane.

m = Δy/Δx

where, m is the slope

1. The co- ordinates of the graph is (0, 0) and (-1, 2)

slope = (2-0) / (-1 - 0) = 2/ (-1) = -2

Thus, the slope is -2.

2. The co-ordinates of the graph is (0, 0) and (4, 4)

slope = (4 - 0) / (4- 0) = 4/4  = 1

Thus, the slope is 1.

3. cost of 7 yards fabric = $45. 43

cost of 1 yards fabric = 45. 43/7

If the bricklayers lay 5% more blocks each day. The function is exponential  and discrete.

An exponential function is a function that increases or decreases at an increasing rate. It does not increase by a constant number.

The form of an  exponential function: [tex]e^{x}[/tex]

Where:

• x = the variable

• e = constant

For example, the blocks layed on the first day is 100.

A discrete variable is a variable that assumes only a finite number of values. A discrete variable can be counted.

A linear function is a function that increases at a constant rate. For example, if the bricklayers lay 100 bricks every day, it can be modelled as a linear function.

A continous variable does not take on a finite number of values. It cannot be counted and it is instead measured.
