The equation of the line is x is -6

A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).

A line's steepness is indicated by its slope. Any line's slope is constant along its length. The direction of the line on the coordinate plane can also be determined by the slope. A line's graph can be used to determine slope, or the coordinates of any two points on a line can be used.

Given ,

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

Using the points given, we have:

m=(3 - 3)/(-5 - 3) = 0

These would be the vertical lines, and vertical lines have an equation with only x.

What is Geometric sequence?

An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.

Given that;

In a geometric sequence,

The third term is 100 and the eighth term is 3.125.

Now,

We know that;

The nth term of geometric sequence is,

⇒ [tex]T_{n} = a r^{n - 1}[/tex]

Hence, The third term is;

⇒ [tex]T_{3} = a r^{3 - 1} = 100[/tex]

⇒ [tex]a r^{2} = 100[/tex]   ..(i)

And, The eighth term is,

⇒ [tex]T_{8} = a r^{8 - 1} = 3.125[/tex]

⇒ [tex]a r^{7} = 3.125[/tex]   ..(ii)

Divide equation (ii) by (i), we get;

⇒ ar⁷ / ar² = 3.125/100

⇒ r⁷ / r² = 3125 / 100000

⇒ r⁷⁻² = 3125 / 100000

⇒ r⁵ = 3125 / 100000

⇒ r = 5/10

The linear equation in the list of equations is y = [tex]\frac{1}{2}x + 3[/tex]

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.

A linear equation must have the highest power of the independent variable as 1.

option A and C, the independent variable x has degree 2

option D the x variable there stands for absolute values.

Answer: f(x) = -3(x + 3)² + 8

Step-by-step explanation:

(h, k) are the coordinates to the vertex of the graph, which in this case would be (-3, 8), so the function for now would be:

[tex]f(x)=a(x+3)^2+8[/tex]

Plug in the coordinates (0, -19) to find the value of a:

What is equation straight line?

There are numerous ways to express the equation of a straight line, including point-slope form, slope-intercept form, general form, standard form, etc. A straight line is a geometric object with two dimensions and infinite lengths at both ends. The formulas for the equation of a straight line that are most frequently employed are y = mx + c and axe + by = c. Other versions include point-slope, slope-intercept, standard, general, and others.

Given two line-side coordinates, use the slope formula to determine the slope of the line. The slope is defined as the ratio of the change in the y values to the change in the x values using the formula m=(y2-y1)/(x2-x1).

The given equation y = -1/5 x + 4.

Here m = -1/5

A square and a rectangle have the same perimeter, then the area of the square and the rectangle are the same.

An object's area is how much space it takes up in two dimensions. It is the measurement of the amount of unit squares which completely encompass the surface of a compact figure. The squared unit, which is frequently expressed as inches, square feet, etc., is the accepted unit of area.

Let x be the side of the square,

The length of the rectangle, l = 2x - 4,

The width of the rectangle, w = x - 6,

So, we have: (2x - 4) × (x -6) = x²,

x = 2 (4 + √10)

= 14.32455 cm, it is the side of the square

14.32455 × 2 -4

=24.6491cm, it is the length of the rectangle.

14.32455 - 6

=8.32455cm, it is the width of the rectangle.

24.6481 × 8.32455 = 14.32455²

Step-by-step explanation:

Any triangle with two equal sides is said to be isosceles .An equilateral triangle has congruent sides, which means that each side is the same length.

Equilateral refers to a triangle with three equally-sized sides. An isosceles triangle is one that has two equal sides.

An equilateral triangle has congruent sides, which means that each side is the same length. Additionally, each inside angle is identical (60 degrees). The words "equi" and "lateral," which both denote sides, are combined to form the phrase "equilateral." As a result, an equilateral triangle is one with equal sides.

The characteristics of an isosceles triangle are as follows: There is agreement between two sides. The base of an isosceles triangle refers to the third side of the triangle, which is unequal to the other two sides. The two angles that are opposite the equal sides line up perfectly.

The perimeter of triangle ABC = 60 + 20√3  cm

What is perimeter?

The complete length of a shape's edge serves as its perimeter in geometric terms. Adding the lengths of all the sides and edges that surround a form yields its perimeter. It is calculated using linear length units such centimeters, meters, inches, and feet.

In triangle ADB,

sin (30°) = AD/AB

1/2 = ( 10 √3 ) /AB

AB  = 20√3

In triangle ABC,

cos (30°) = AB/BC

√3 /2 =  20√3 / BC

BC = 40

tan (30°) = AC/AB

1/√3 =  AC/ 20√3

AC = 20

Perimeter of triangle ABC =  AB +BC  + AC

g(x) is a translation of 4 units to the right, so the correct option is a: k = -4.

We know that:

g(x) = f(x + k)

This means that g(x) is a horizontal translation of f(x) of k units.

if k > 0 the translation is to the left.

if k < 0  the translation is to the right.

We know that f(x) passes through (0, 0) and (2, 2)

so f(0) = 0

And g(x) passes through (4, 0) and (-2, 2)

This means that:

g(4) = f(0)

f(4 + k) = f(0)
