Step-by-step explanation:

1.)  Add 11 to both sides.

-9+1<8(r-17)−9+1<8(r−17)

2.) Simplify  -9+1−9+1  to  -8−8.

-8<8(r-17)−8<8(r−17)

3.) Divide both sides by 88.

-1<r-17−1<r−17

4.) Add 1717 to both sides.

-1+17<r−1+17<r

5.) Simplify  -1+17−1+17  to  16.

16<r16<r

6.) Switch sides.

Answer:

y = 3/4x + 12

Step-by-step explanation:

let equation of the line be y = 3/4x + b

sub (-8, 6):

6 = 3/4(-8) + b

12 = b

therefore equation of the line is y = 3/4x + 12

General Form of Equation of a line that passes through the point (-8,6) and has a slope of 3/4 is:

[tex]\frac{3}{4}x-y+12=0[/tex]

Step-by-step explanation:

We need to find equation of line that passes through the point (-8,6) and has a slope of 3/4 in general form.

The general form of linear equation is [tex]Ax+By+C=0[/tex]

First we will use slope-intercept form i.e, [tex]y=mx+b[/tex] to find equation and then write it in general form.

Where m is slope and b is y-intercept.

We are given slope = 3/4 but y-intercept is not given and we need to find.

Finding y-intercept

Using the point (-8,6) and slope m = 3/4 we can find y-intercept

[tex]y=mx+b\\6=\frac{3}{4}(-8)+b\\6=3(-2)+b\\6=-6+b\\b=6+6\\b=12[/tex]

So, y-intercept b is 12

Equation of line

The line has slope m=3/4 and y-intercept b is 12, the equation is:

[tex]y=mx+b\\y=\frac{3}{4}x+12[/tex]

General Form of Equation of a line that passes through the point (-8,6) and has a slope of 3/4 is:

[tex]\frac{3}{4}x-y+12=0[/tex]

Answer:

2. 8n. 8n. 8n. 8n

Step-by-step explanation:

[tex]2 {(8n)}^{4} = 2. 8n. 8n. 8n. 8n[/tex]

Equivalent expressions are expressions with equal value.

The equivalent expression of [tex]\mathbf{2\cdot(8n)^4}[/tex] is [tex]\mathbf{2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}[/tex]

The expression is given as:

[tex]\mathbf{2\cdot(8n)^4}[/tex]

Apply law of indices

[tex]\mathbf{2\cdot(8n)^4 = 2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}[/tex]

The above equation means that:

[tex]\mathbf{2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}[/tex] is equivalent to [tex]\mathbf{2\cdot(8n)^4}[/tex]

Hence, the correct option is (d) [tex]\mathbf{2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}[/tex]

Answer:

1.11111=111111100000

Showing the work

Rewrite the decimal number as a fraction with 1 in the denominator

1.11111=1.111111

Multiply to remove 5 decimal places. Here, you multiply top and bottom by 105 = 100000

1.111111×100000100000=111111100000

Simplify the improper fraction,

=111111100000

In conclusion,

1.11111=111111100000

Step-by-step explanation:

The fraction equivalent of the repeating decimal 1.11111 is 10/9. This means that 1.11111 is equivalent to 10/9, indicating a ratio of 10 parts to 9 parts. Simplifying the fraction ensures that it is in its simplest form with no common factors between the numerator and the denominator other than 1.

To express the decimal 1.11111 as a fraction, we can use algebraic manipulation. Let's denote the repeating decimal as x:

x = 1.11111...

To eliminate the repeating part, we can multiply x by 10:

10x = 11.11111...

Now, we can subtract the original equation from the multiplied equation to eliminate the repeating part:

10x - x = 11.11111... - 1.11111...

Simplifying the equation:

9x = 10

Dividing both sides by 9:

x = 10/9

Therefore, the fraction equivalent of the repeating decimal 1.11111 is 10/9. This means that 1.11111 is equivalent to 10/9, indicating a ratio of 10 parts to 9 parts. Simplifying the fraction ensures that it is in its simplest form with no common factors between the numerator and the denominator other than 1.

Answer:

Step-by-step explanation:

If Daniela has 2 1/4 basketball games left to play in a tournament, and she has 3/4 gallon of water left to drink, since she drinks the same amount in each game, we can say;

2 1/4 games = 3/4 gallons

To calculate how much he has to drink in a game, this can be expressed as;

1 game = x gallon

Solve for x;

2 1/4 games = 3/4 gallons

1 game = x gallon

Cross multiply

3/4 = 2 1/4x

3/4 = 9/4 x

9x/4 = 3/4

cross multiply;

9x * 4 = 4*3

36x = 12

x = 12/36

x = 1/3

Hence she can drink 1/3 gallons of water in each game.

Answer:

x = 20°

y = 19°

Step-by-step explanation:

The first two angles that are in the 2nd Quadrant:

2x - 3

3x - 7

The rule states that the two angles are complimentary angles that form an angle of 90°. So,

(2x - 3) + (3x - 7) = 90

2x - 3 + 3x - 7 = 90

2x + 3x - 3 - 7 = 90

5x - 10 = 90

5x = 90 + 10

5x = 100

x = 100 ÷ 5

x = 20

Another rule applies here, vertical angles are equivalent to each other.

So,

2x - 3 = 2y - 1

2(20) - 3 = 2y - 1

40 - 3 = 2y - 1

37 = 2y - 1

37 + 1 = 2y

38 = 2y

38 ÷ 2 = y

19 = y

And we have our answer!

A. Use the law of cosines:

29² = 34² + c ² - 2•34•c cos(30.3°)

Use a calculator to solve for c ; notice this equation is quadratic, you get two possible solutions, c ≈ 5.973 ≈ 6 or c ≈ 52.738 ≈ 53.

Then use the law of sines to solve for the two possibles measures of angle C :

sin(30.3°)/29 = sin(C )/c

sin(C ) = c sin(30.3°)/29

sin(C ) ≈ 0.1039   or   sin(C ) ≈ 0.9175

C ≈ 6.0°   or   C ≈ 66.6°

The interior angles of any triangle sum to 180°, so the remaining angle has measure either

B = 180° - 30.3° - C

B ≈ 143.7°   or   B ≈ 83.1°

So to recap,

B ≈ 143.7°, C ≈ 6.0°, c ≈ 6

and

B ≈ 83.1°, C ≈ 66.6°, c ≈ 53
