Step-by-step explanation:

Linear functions are straight lines.

The first three terms of the given sequence are 1, -3, and -7 respectively.

What are sequence and series?

An arrangement of numbers in a specific order is referred to as a sequence. The total of a sequence's components, on the other hand, is known as a series.

Given, the [tex]n^{th}[/tex] term of a sequence is: [tex]u_{n}[/tex] = 5 - 4n

We need to find the first three terms, then n= 1, 2, 3 respectively

So, first term, n = 1, [tex]u_{1}[/tex] = 5 - 4*1 = 5 - 4 = 1

second term, n = 2, [tex]u_{2}[/tex] = 5 - 4*2 = 5 - 8 = -3

third term, n = 3, [tex]u_{3}[/tex] = 5 - 4*3 = 5 - 12 = -7

Hence, the first three terms of the sequence are 1, -3, and -7 respectively.

Answer: 26

Step-by-step explanation:

let t = thomas's age

104 = (3t) + t

104 = 4t

t = 26

Answer: 26 years old

Step-by-step explanation:

    We will write a system of equations to help us solve, let h be equal to Huilan's age and t be equal to Thomas's age.

         h = 3t

         h + t = 104

    Now, we will solve by substituting the first equation into the second.

    Then, we will simplify the equation on the left side by combining like terms and dividing both sides of the equation by 4 to isolate the variable.

         h + t = 104

         (3t) + t = 104

         4t = 104

Answer:

ANS:- 67

Step-by-step explanation:

d = a2 - a1

a2 = 307, a1 = 313

d = 307 -313 = -6

an = a1 + (n - 1)d

a1 = 313, n = 42, d = -6

a42 = 313 + (42 -1)(-6)

a42 = 313 + (41)(-6)

a42 = 313 - 246

a42 = 67

This is my method.

Take two points.

(X₁ = -8, Y₁ = 8)

(X₂ = -3, Y₂ = 4.875 or 4 7/8)

Equation of a straight line:

y = mx + b ------(i)

Step 1: Calculating Slope (m).

[tex]\frac{y_2-y_1}{x_2-x_1 }[/tex]

[tex]\frac{4.875-8}{-3--8}[/tex]

[tex]\frac{-3.12500}{5}[/tex]

[tex]m=-0.625[/tex]

Now putting value of m in equation (i)

  y = -0.625x + b -----(ii)

Step 2: Calculating Y-intercept (b).

Lets choose the first point, (-8,8) for calculating y-intercept:

y = mx + b

8 = -0.625(-8) + b

8 = 5 + b

3 = b

b = 3

Now putting value of b in equation (ii)

y = -0.625x + 3

This is slope-intercept form, now let's convert to point-slope formula.

The simplest form of 210/945 is 2/9

Step-by-step explanation:

Through a given point not contained in a given line, there exists exactly one line parallel to the given line.

In Mathematics, parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and they can never meet. In Geometry, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m represents the slope.

This ultimately implies that, two (2) lines would be parallel to each other when the slope (m₁) of the first line is equal to the slope (m₂) of the second line.

According to the Parallel postulate, there is always exactly one line that is parallel to a given line in the same plane when a point and a line are given, provided that the point is not on that line.

Since this is an isosceles triangle, the two angles opposite the congruent sides are also congruent. That means that ∠A and ∠C both equal 73°, you don't even need to solve the equation with y in it. Since all the angles in a triangle add up to 180°, we know that ∠B is equal to [tex]180-(73*2)[/tex], which is 34. So if [tex]34=6x+4[/tex], then you can solve to get [tex]x=5[/tex].

We know that,

Take the equation

The equation of line which is perpendicular to the given line and passes through the points ( 3, 4) is y = 3x + 5

The slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible.

The slope intercept form of a straight line equation can be written as :

y = mx + c

Where

m = slope = (change in the y-value) axis's / (change in the value of x in the x axis)

The given line's equation is

y = - x/3 + 5

Slope = - 1/3 as compared to the slope intercept form.

The slope of one line is equal to the negative reciprocal of the slope of the other line if two lines are perpendicular.

As a result, the slope of the line through (3, 4) is 3.

In order to calculate the intercept, we would replace m with 3, x with 3 and y with 4

The equation becomes

4 = 3 × 3 + c

c = -5

putting the value of c and m in the slope intercept form equation

We get

y = 3x - 5

Step-by-step explanation:

The first equation of a system of equations is y = -3x + 4 and the second equation is y = -3x - 4.

We can see that both equations have the same slope of -3 and have different y-intercepts of 4 and -4, respectively.

Because the two lines are parallel, they will never intersect and will overlap each other, resulting in an infinite number of solutions.

Therefore, the system of equations y = –3x + 4 and y = –3x – 4 has infinitely many solutions.

The perimeter of a regular octagon with side s is 8s.Each side of the planter will be 9 inches long.

The length of a shape's outline is its perimeter. You must add the lengths of all four sides of a rectangle or square to determine its perimeter.

The distance around an object is called the perimeter. For instance, the yard of your home is fenced in. The fence's length serves as the perimeter.

The perimeter of a regular octagon with side s is 8s.

Each side of the planter will be 9 inches long.

A linear regression equation that represents this set of data is y = 31x + 799.8.

The calendar year in which the number of new cases would reach 1141 is 2022.

In this scenario, the Year since 2011 (x) would be plotted on the x-axis of the scatterplot while the New cases (y) would be plotted on the x-axis of the scatterplot.

On the Excel sheet, you should right click on any data point on the scatterplot, select format trend line and then tick the box to display an equation for the linear regression (line of best fit) on the graph.

By critically observing the scatterplot (see attachment) which models the relationship given in the table for the Year since 2011 (x) and the New cases (y), an equation for the linear regression is given by:

y = 31x + 799.8

Now, we can estimate the calendar year in which the number of new cases would reach 1141:

1141 = 31x + 799.8

31x = 1141 - 799.8

31x = 341.2

x = 341.2/31

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Describe a linear example?

Any function that depicts a straight line on the coordinate plane is said to be linear. For instance, the equation y = 3x – 2 represents a straight line on a coordinate plane, indicating that it is a linear function.

                         This function can be expressed as f(x) = 3x - 2 since y can be replaced with f(x).
