Answer:

(D): (-1,-6)

Step-by-step explanation:

Given

[tex](x_1,y_1) = (-2,-5)[/tex]

[tex]m = -1[/tex]

Required

Find [tex](x_2,y_2)[/tex]

Slope (m) is calculated using:

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

Substitute values for m, x1 and x2

[tex]-1 = \frac{y_2 -(-5)}{x_2 - (-2)}[/tex]

[tex]-1 = \frac{y_2 +5}{x_2 +2}[/tex]

Cross Multiply:

[tex]-1(x_2 +2) = y_2 +5[/tex]

[tex]-x_2 -2 = y_2 +5[/tex]

Make y the subject

[tex]y_2 = -x_2 - 2 - 5[/tex]

[tex]y_2 = -x_2 - 7[/tex]

Only (D): (-1,-6) satisfy this condition:

Substitute -1 for x2 and -6 for y2.

[tex]-6 = -(-1) - 7[/tex]

[tex]-6 = 1- 7[/tex]

[tex]-6 =- 6[/tex]

Hence:

(D): (-1,-6) is true

Answer:

14+7b

Step-by-step explanation:

8+6=14

4b+3b=7b

Answer:

14 +7b

Step-by-step explanation:

Combine like terms. Like terms have same variables

8 + 4b + 3b + 6 = 8 + 6 + 4b + 3b

                           = 14 + 7b

Answer:

c

Step-by-step explanation:

divide 1/5,280 and then multiply that by 6,600

Answer:

the answer is c

Step-by-step explanation:

multiply 6,600 by 1 and that will give you 6,600 again

after that you divide 6,600 and 5,280 that will get you 1.25

if you think I'm wrong just do it on the calculator it will give you 1.25

have a nice day!!

Answer:

The answer is J,

it can't be H because that would increase the size by 10, when the problem describes a reduction. and it cant be F or G because it has the x and y values in the wrong spots.

Answer:

associative, commutative, no, multipolication by 1 (don know what that is called),  commutative, no, adding by 0, no

Step-by-step explanation:

3 and 6 are no because subtraction is not associative

what is the question?

Step-by-step explanation:

all u have is the numbers

Answer:

D. (-2, 6)

Step-by-step explanation:

First, isolate a variable in one of the equations (i.e y = or x =)

The first equation already has isolated x.

x = y - 8 or y - 8 = x

5x + y = -4

Substitute the isolated variable into the second equation.

5(y-8) + y = -4

There is now only one variable, y, in the equation. Now you can solve for y.

First, use the distributive property to get the equation

5y - 40 + y = -4

Then, add 40 to both sides.

5y + y = 36

Add like-terms.

6y = 36

Divide.

36 / 6 = 6

So, y = 6.

Now that we have one coordinate, y = 6, you can substitute for y in the first equation.

x = 6 - 8

Subtract.

x = -2

Your coordinates are now x = -2 and y = 6, or (-2, 6).

0

Answer:

[tex]\boxed {\boxed {\sf 40 \pi \ cm, 125.6 \ cm, or \ 125.6637061 \ cm}}[/tex]

Step-by-step explanation:

Circumference can be found by multiplying the diameter of the circle by pi.

[tex]c= \pi d[/tex]

We are given the radius, which is 20 centimeters. We need the diameter, which is twice the radius.

[tex]d= 2r[/tex]

[tex]d= 2(20 \ cm)[/tex]

[tex]d= 40 \ cm[/tex]

Substitute the diameter into the formula. There are many ways to calculate circumference, so I included a few options.

1. In Terms of Pi

If we solve in terms of pi, we leave π in the answer.

[tex]c=\pi ( 40 \ cm)[/tex]

[tex]c= 40 \pi \ cm[/tex]

2. Using 3.14 as Pi

[tex]c=\pi ( 40 \ cm)[/tex]

Substitute 3.14 in for pi.

[tex]c= (3.14)(40 \ cm)[/tex]

[tex]c=125.6 \ cm[/tex]

3. Using 3.14159 as PI

[tex]c=\pi ( 40 \ cm)[/tex]

Use the pi button on a calculator.

[tex]c= 125.6637061 \ cm[/tex]

The circumference of the light fixture is 40π, 125.6 cm, or 125.6637061 cm

Question:

Lisa walks at an average speed of  6 km/h for 15 hours.

Dan completes the same distance in  an hour.  Calculate Dan's average speed.​

Answer:

[tex]Speed = 90km/hr[/tex]

Step-by-step explanation:

Given

Lisa:

[tex]Speed = 6km/hr[/tex]

[tex]Time = 15\ hr[/tex]

First, we calculate the distance covered by Lisa:

[tex]Distance = Speed * Time[/tex]

[tex]Distance = 6km/hr * 15\ hr[/tex]

[tex]Distance = 90km[/tex]

So, Dan distance can be represented as:

[tex]Distance = 90km[/tex] --- Dan completes the same distance as Lisa

[tex]Time = 1\ hr[/tex] -- Time to complete the distance

Dan's average speed is:

[tex]Speed = \frac{Distance}{Time}[/tex]

[tex]Speed = \frac{90km}{1\ hr}[/tex]

[tex]Speed = 90km/hr[/tex]

Hence, Dan's average speed is 90km/hr

Answer:

Step-by-step explanation:

area of a whole circle is pi [tex]r^{2}[/tex]

diameter is 2*r

1/2 * pi * [tex]6^{2}[/tex]   will find the area of 1/2 of the circle that has a diameter of 12'

56.54866 '

so approx  60 ft

Answer:

28 pieces

Step-by-step explanation:

Answer:

The x-value at which the two functions' values are equal is 5.

Step-by-step explanation:

Let [tex]f(x) = 3[/tex] and [tex]g(x) = x-2[/tex], if [tex]f(x) = g(x)[/tex], then:

[tex]x - 2 = 3[/tex]

[tex]x = 3+2[/tex]

[tex]x = 5[/tex]

The x-value at which the two functions' values are equal is 5.

Answer:
