Step-by-step explanation:

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).

Write three equivalent ratios

To solve these questions, we do the following:

Whatever is being applied to a part of the ratio must be done on the other part

Solving (9):

[tex]Ratio = \frac{2}{7}[/tex]

Multiply through by 2

[tex]Ratio = \frac{2*2}{7*2} = \frac{4}{14}[/tex]

Multiply through by 3

[tex]Ratio = \frac{2*3}{7*3} = \frac{6}{21}[/tex]

Multiply through by 5

[tex]Ratio = \frac{2*5}{7*5} = \frac{10}{35}[/tex]

Hence, the equivalents are: [tex]\frac{4}{14}, \frac{6}{21}, \frac{10}{35}[/tex]

Solving (10):

Ratio = 1.5 to 3.5

Multiply by 2

[tex]Ratio = 1.5 * 2\ to\ 3.5 * 2[/tex]

[tex]Ratio = 3\ to\ 7[/tex]

Multiply by 3

[tex]Ratio = 1.5 * 3\ to\ 3.5 * 3[/tex]

[tex]Ratio = 4.5\ to\ 10.5[/tex]

Multiply by 4

[tex]Ratio = 1.5 * 4\ to\ 3.5 * 4[/tex]

[tex]Ratio = 6\ to\ 14[/tex]

Hence, the equivalents are:  3 to 7, 4.5 to 10.5 and 6 to 14

Solving (11):

Ratio = 6.25 to 1.25

Divide by 5

[tex]Ratio = 6.25/5\ to\ 1.25/5[/tex]

[tex]Ratio = 1.25\ to\ 0.25[/tex]

Multiply by 2

[tex]Ratio = 6.25*2\ to\ 1.25*2[/tex]

[tex]Ratio = 12.5\ to\ 2.5[/tex]

Multiply by 4

[tex]Ratio = 6.25*4\ to\ 1.25*4[/tex]

[tex]Ratio = 25\ to\ 5[/tex]

Hence, the equivalents are:  1.25 to 0.25, 12.5 to 2.5 and 25 to 5

Solving (12):

[tex]Ratio = 3 : 3\frac{1}{2}[/tex]

Multiply by 2

[tex]Ratio = 3 *2: 3\frac{1}{2}*2[/tex]

[tex]Ratio = 6: 7[/tex]

Multiply by 4

[tex]Ratio = 3 *4: 3\frac{1}{2}*4[/tex]

[tex]Ratio = 12: 14[/tex]

Multiply by 6

[tex]Ratio = 3 *6: 3\frac{1}{2}*6[/tex]

[tex]Ratio = 18: 21[/tex]

Hence, the equivalents are: 6:7, 12:14 and 18:21

Solving (13)

[tex]Ratio = 1\frac{2}{3} : \frac{5}{4}[/tex]

Convert mixed fraction to improper fraction

[tex]Ratio = \frac{5}{3} : \frac{5}{4}[/tex]

Multiply by 2

[tex]Ratio = \frac{5}{3}*2 : \frac{5}{4}*2[/tex]

[tex]Ratio = \frac{10}{3} : \frac{5}{2}[/tex]

Multiply by 3

[tex]Ratio = \frac{5}{3}*3 : \frac{5}{4}*3[/tex]

[tex]Ratio = 5 : \frac{15}{4}[/tex]

Multiply by 12

[tex]Ratio = \frac{5}{3}*12 : \frac{5}{4}*12[/tex]

[tex]Ratio = 20 : 15[/tex]

Hence, the equivalents are: 10/3:5/2, 5 : 15/4, and 20:15

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:

[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

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:

which one????????????????????

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!!
