Hey, there!!

The given is a point (-6,8) through which a line passes. And is perpendicular to the line y = 2x-4

The equation for point (-6,8) is,

(y-8)= m1(x+6)...........(i)

and given equation is y = 2x-4............(ii)

Now, from equation (ii).

slope (m2)= 2 { as equation (ii) is in the form of y= mx+c where m is a slope}.

Now, For perpendicular,

m1×m2= -1

m1×2= -1

[tex]m1 = \frac{ - 1}{2} [/tex]

Therefore, m1 = -1/2.

Putting, the value of m1 in equation (i).

(y-8) = -1/2×(x+6)

2(y-8)= -1(x+6)

2y - 16 = -x -6

x+2y-10 = 0......... is the required equation.

Hope it helps...

Step-by-step explanation:

The Population pyramids or the age pyramid visualizes the demographic structure of any population. It is the graphical illustration which shows the distribution of the various age groups in the population.

The width of the pyramid represents the size of a population for a given age. Men are shown to the left and the women on the right.

The population pyramid between the age group will look like a pyramid with a very large width at the bottom and narrowing top.

Answer:

2a² = c²

Step-by-step explanation:

Right triangles follow the Pythagorean Theorem, a² + b² = c². The hypotenuse (c) must be the longest of the sides. In the given triangle, both legs measure a units. So, a = b. Therefore, we have a² + a² = c² or 2a² = c².

The equation can be used to determine if the triangle is a right triangle is c² = 2a².

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagorean theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

The well-known Pythagorean Theorem states that the square on the hypotenuse of a right triangle equals the sum of the squares on its legs.

The longest side measures c units.

The other sides of the triangle measure a units.

As, we know that longest side is the Hypotenuse.

Using the Pythagorean Theorem

H² = P² + B²

c² = a² + a²

c² = 2a²

So, the Correct statement is c² = 2a².

Answer:

  B = (6, 4)

Step-by-step explanation:

You know that the midpoint is calculated as ...

  M = (A +B)/2

Solving this for B, we find ...

  2M = A + B

  B = 2M - A

Filling in the coordinate values, we get ...

  B = 2(5, -2) -(4, -8) = (2·5-4, 2(-2)+8)

  B = (6, 4)

Answer:

He is watching TV for 2 hours and 40 minutes.

Step-by-step explanation:

We are given that the episodes of a TV program are each 40 minutes long. Phill watches four episodes together.

As it is stated that the length of each episode of a TV program is 40 minutes, so the length of four episodes is given by;

1 episode = 40 minutes

4 episodes = 4 [tex]\times[/tex] 40

                  = 160 minutes

So, the length of four episodes together is 160 minutes.

Now, we have to convert the time in hours and minutes;

As we know that 1 hour = 60 minutes

160 minutes = 120 minutes + 40 minutes

                    = 2 hours + 40 minutes

Hence, the length of four episodes together is 2 hours and 40 minutes.

Answer:

The current population (in 2005) is 4000 because it is the constant. The slope tells us how many people are added to the population, so 70 per year. For ex. 2008 (2008- 2005 = 3=> 3 x 70 = 210 => 210 + 4000 = 4210).

Answer:

15÷4÷1/6.

first of all change ÷ to ×.

which will be 15×1/4×6/1.

which will be 15×1/2×3.

which is 15×3=45/2.

the answer is 22.5 or 22 whole number 1/2.

15 divided by 4 and 1/6 is equal to 18/5 or 3 and 3/5.

To divide 15 by 4 and 1/6, we can convert the mixed number 4 and 1/6 into an improper fraction.

4 and 1/6 can be written as (4 x 6 + 1) / 6 = 25/6.

Now, we can divide 15 by 25/6:

15 ÷ (25/6) = 15 x (6/25)

= (15 x 6) / 25

= 90/25.

Now, the fraction 90/25 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5:

= 90/25

= (90 ÷ 5) / (25 ÷ 5)

= 18/5.

Therefore, 15 divided by 4 and 1/6 is equal to 18/5 or 3 and 3/5.

Answer:

type the question that is the answer

Step-by-step explanation:

Answer:

It has exactly 3 congruent sides.

Step-by-step explanation:

Since ∠FGJ = ∠JGH = 30° and GJ is a perpendicular bisector of FH, ∠GJF = 90°. So in ΔFGJ, ∠FGJ + ∠GJF  + ∠GFJ = 180°.

So, 30° + 90° + ∠GFJ = 180°

120° + ∠GFJ = 180°

∠GFJ = 180° - 120°

∠GFJ = 60°

Also, since GJ is the perpendicular bisector of FH, ∠GJH = 90°. So in ΔJGH, ∠JGH + ∠GJH  + ∠JHG = 180°.

So, 30° + 90° + ∠JHG = 180°

120° + ∠JHG = 180°

∠JHG = 180° - 120°

∠JHG = 60°

Since ∠FGH = ∠FGJ + ∠JGH = 30° + 30° = 60°

Since ∠FGH = ∠GFJ = ∠JHG = 60°

So, ΔFGJ is an equilateral triangle. Since all its angles are equal, so also, all its sides are equal. So, ΔFGJ is congruent by SSS and AAA so its 3 sides are congruent.

So exactly 3 sides are congruent in ΔFGJ.

Answer:

An expression for the area of the rectangle if the width is w inches is

[tex]A =[/tex] 3w

when the width is 1 inch, Area = 3 square inches (in²)

when the width is 2 inches, Area = 6 square inches (in²)

when the width is 3 inches, Area = 9 square inches (in²)

when the width is 26 inches, Area = 78 square inches (in²)

Step-by-step explanation:

The area of a rectangle is given by

[tex]A = l[/tex] × [tex]w[/tex]

Where [tex]A[/tex] is the area of the rectangle

[tex]l[/tex] is the length of the rectangle

and [tex]w[/tex] is the width of the rectangle

From the question,

length, [tex]l[/tex] = 3 inches

width, [tex]w[/tex] = w inches

Hence, An expression for the area of the rectangle is

[tex]A =[/tex] 3 × w

[tex]A =[/tex] 3w

Now, to find the area of the rectangle when the width is 1, 2 , 3, and 26 inches

1. when the width is 1 inch (That is [tex]w[/tex]  = 1 inch)

Then, [tex]A =[/tex] 3w

[tex]A =[/tex] 3 × 1

[tex]A =[/tex] 3 square inches (in²)

2. when the width is 2 inches (That is [tex]w[/tex]  = 2 inches)

Then, [tex]A =[/tex] 3w

[tex]A =[/tex] 3 × 2

[tex]A =[/tex] 6 square inches (in²)

3. when the width is 3 inches (That is [tex]w[/tex]  = 3 inches)

Then, [tex]A =[/tex] 3w

[tex]A =[/tex] 3 × 3

[tex]A =[/tex] 9 square inches (in²)

4. when the width is 26 inches (That is [tex]w[/tex]  = 26 inches)

Then, [tex]A =[/tex] 3w

[tex]A =[/tex] 3 × 26

[tex]A =[/tex] 78 square inches (in²)

Answer: True

If one variable goes down, then the other goes up, and vice versa. Think of it like a see-saw. We'll have x on one side pushing down to make y go up. An example of this would be y = 1/x which graphs out a hyperbola.

The statement "two variables is inverse when a decrease in one variable is associated with an increase in the other variable." is True statement.

One kind of proportionality relationship is inverse proportion. If two quantities are inversely related, one will increase while the other will decrease. Building a wall would be an example of an inverse proportion in action.

Given:

We know in direct relation if one quantity increase then another quantity increase.

and, in Inverse Relation if one quantity increase then other Quantity decrease.

So, two variables is inverse when a decrease in one variable is associated with an increase in the other variable is true statement.
