I did this is school. Perpendicular is kinda like the opposite of the line so instead of being a positive line you would make the slope negative and make the line negative

Hope I explained this right

Determine the equation of the line perpendicular to the line y = -8 through the point (-4,-2).

ludmilkaskok [199]

The line y = -8 is horizontal

The line perpendicular to the line y = -8 is vertical

The equation of the line perpendicular to the line y = -8 through

the point (-4 , -2) is x = -4

Step-by-step explanation:

Let us revise some notes about the vertical and horizontal lines

The equation of a horizontal line passes through point (a , b) is y = b, because the y-coordinates of all points on the line are equal
The equation of a vertical line passes through point (a , b) is x = a, because the x-coordinates of all points on the line are equal
The horizontal line and the vertical line are perpendicular to each other

We need to find the equation of the line perpendicular to the line y = -8 through the point (-4 , -2)

∵ The equation of the given line is y = -8

∴ The given line is a horizontal line

The line y = -8 is horizontal

∵ The line y = -8 is a horizontal

∴ The line perpendicular to it must be vertical

The line perpendicular to the line y = -8 is vertical

∵ The equation of a vertical line is x = a, where a is the x-coordinate

of a point lies on the line

∵ The line perpendicular to the line y = -8 through the point (-4 , -2)

∴ a = -4

∴ The equation of the perpendicular line is x = -4

The equation of the line perpendicular to the line y = -8 through

the point (-4 , -2) is x = -4

Triangle ABC is given by the points A(3, 2), B (4, 4), and C(5, 1). Select True or False for each statement.

oksano4ka [1.4K]

Answer:

C. The perimeter of ΔABC is 7.6 units.

Step-by-step explanation:

Triangle ABC is given by the points A(3, 2), B(4, 4), and C(5, 1). Determine if each statement is True or False.

A. The perimeter of ΔABC is 9.9 units.

B. ΔABC is an equilateral triangle.

C. The perimeter of ΔABC is 7.6 units.

Solution:

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, scalene, acute, obtuse and right angled triangle.

The distance between two points (x₁, y₁) and (x₂, y₂) in the coordinate plane is:

$Distance=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Given the vertices of triangle ABC as A(3, 2), B(4, 4), and C(5, 1). Therefore we have to calculate the side lengths of the triangle:

$AB=\sqrt{(4-3)^2+(4-2)^2}=\sqrt{1+4}=\sqrt{5} \\\\AC=\sqrt{(5-3)^2+*(1-2)^2}=\sqrt{4+1}=\sqrt{5} \\\\BC=\sqrt{(5-4)^2+(1-4)^2}=\sqrt{1+9}=\sqrt{10}$

1) Perimeter of the triangle = AB + AC + BC = √5 + √5 + √10 = 7.6 units

2) Since only two sides of the triangle are equal (i.e. AB = AC), hence the triangle is an isosceles triangle.

Does anyone know how to do these? I don’t want the answers I need someone to explain how to do them so I can solve it. Thanks

Hi! This type of equation is actully really simple to solve once you learn how so I'll only do a few and let you solve the rest.

To solve 3x + 6 = 18 you just need to remember that whatever action you do on one side of the equal sign you have to do on the other as well, and you just need to get the variable isolated on one side and the constant on the other.

So subtract 6 from both of the constants (6 and 18) to get to 3x = 12.

Then divide both sides by 3 to isolate x and you get x = 4.

To solve x/7 -9 = -7 you have to add 9 to both sides to get x/7 = 2. Then because it's a fraction with a denominator of 7 you multiply both sides by 7 to get x = 14.

To solve 8x - 2x = -36 you combine like terms to get 6x = -36 then divide both sides by 6 to get x = -6.

Hope this is what you were looking for and explained in an understandable way, if not I apologize. :)
