Gwen is attending a school orchestra concert. She sees her math teacher seated 3 meters ahead of her and her science teacher seated 4 meters to her right. How far apart are the two teachers?

5 metres, using Pythagorean triples as one is infront one is to the right meaning the distance betweent them would create a triangle so u can calculate it to be 5

What is the slope of the line containing (–1, 8) and (3, –12)? A. 5 B. – C. –5 D.

**Answer:**

-5

**Step-by-step explanation:**

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

=(-12 -8)/(3 - -1)

=(-12-8)/(3+1)

= -20/4

= -5

what is the answer to 15 and 18? pls help it will mean a lot:)

**Answer and Step-by-step explanation:**

**15. **[tex]-\frac{27}{20}[/tex] or [tex]-1\frac{7}{20}[/tex]

-1.35 = -135/100 = [tex]-1\frac{35}{100}[/tex] (Mixed number)

Multiply the number by 100, then divide the number by 100 (but keep it in fraction form).

-1.35 x 100 = -135

[tex]-\frac{135}{100}[/tex] = [tex]-\frac{27}{20}[/tex]

(Mixed Fraction = . To check, multiply the 20 by the 1, then add 7, to get -27/20)

**18. ** [tex]\frac{49}{11}[/tex]** **or [tex]4\frac{5}{11}[/tex]

4.45 = 49/11 = [tex]4\frac{5}{11}[/tex]

4.4545.....

Multiply the number by 100 (because there is 2 numbers being repeated.

445.4545....

Now subtract by the original number.

445.4545....

- 4.4545....

441.00

Write this as an equation:

(100 x fraction) - fraction = 441 (100 x fraction) - fraction = 99 x fraction

99 x fraction = 441 (Divide both sides by 99)

fraction = [tex]\frac{441}{99}[/tex] (which simplifies down to [tex]\frac{49}{11}[/tex])

Find the distance between the ponits.

(-3, -6) and (3, x6)

Help please

**Step-by-step explanation:**

Hey there!

The given points are: (-3,-6) and (3,-6).

x 1 = -3 y1 = -6

x 2 = 3 y2 = -6

Use distance formula;

[tex]d = \sqrt{( {x2 - x1)}^{2} + ( {y2 - y1)}^{2} } [/tex]

Keep all the values;

[tex]d = \sqrt{( {3 - ( - 3))}^{2} + ( { - 6 - ( - 6))}^{2} } [/tex]

Simplify:

[tex]d = \sqrt{ {(6)}^{2} + {( - 6 + 6)}^{2} } [/tex]

[tex]d = \sqrt{ {(6)}^{2} } [/tex]

**Therefore, the distance is 6 units.**

**Hope it helps!**

Thomas has 3 boxes, each with 8 balls.

He wants to place the balls evenly into 4 boxes.

How many balls will be in each of the 4 boxes?

Answer: 6 balls will be in each of the 4 boxes.

Step-by-step explanation:

Multiply 3x8 to find out how many balls there are total.

3x8=24

Then to split them evenly, you divide by 4 (the amount of boxes they are split into)

24/4= 6

SOMEONE HELP ME PLEASE AND SHOW WORK

Hi! I'm happy to help!

To solve for WX, we have to find the length of the part of the line that isn't XY. Since we know the full length of the line, we subtract the length of XY from WY to get WX:

100-89.6

10.4

**The length of WX is 10.4 centimeters.**

I hope this was helpful, keep learning :D

**Answer: WX = 10.4 cm**

**Concept:**

Here, we need to know the idea of the segment addition postulate.

The **Segment Addition Postulate** states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

**Solve:**

Given information

XY = 89.6 cm

WY = 100 cm

Given expression deducted from the segment addition postulate

WX = WY - XY

Substitute values into the expression

WX = 100 - 89.6

Simplify by subtraction

WX = [tex]\boxed{10.4cm}[/tex]

Hope this helps!! :)

8x-4(x-3)-3(2x+5)-6

**Answer:**

**8x - 4x + 12 - 6x - 15 - 6**

*Combine like terms*

**-2x - 9**

*If your equation is equal to zero then continue down.*

**-2x - 9 = 0**

**-2x = 9**

**x = -9/2**

** = -4 1/2**

In 2015, 120000 people voted. The number of viewers who voted in 2015 was 20% more than those in 2014. Calculate the numbers of viewers who voted in 2014

**Answer:**

Given;

120,000 people voted in 2015.

In 2015, 20% more people voted than 2014.

Therefore:

How many more people voted in 2015 = 20% of 120,000

= 24,000

Total number of people voted in 2014 = 120,000 - 24,000

= 96,000

Ans) 96,000 people voted in 2014.

How to find the absolute value of |2x+3|=13

**Answer:**

x=5 or x = -8

**Step-by-step explanation:**

|2x+3|=13

There are two solutions to this problem, one positive and one negative

2x+3 =13 and 2x+3 = -13

Subtract 3 from all sides

2x+3-3 = 13-3 2x+3-3 = -13-3

2x = 10 2x = -16

Divide each side by 2

2x/2=10/2 2x/2 = -16/2

x = 5 x = -8

6x+6=-5+3x+17

I need help

**Answer:**

Get all the terms with x on the left. Get all the terms without x on the right. Simplify by adding and subtracting the terms without x and adding and subtracting the terms with x. Finally divide to get the value of x.

**Step-by-step explanation:**

6x+6 =- 5+3x+17

6x+6 -6 =- 5+3x+17 -6

6x = 5+3x+11

6x = 3x + 16

6x - 3x = 3x + 16 -3x

3x = 16

3x / 3 = 16 / 3

x = 15/3 + 1/3

x = 5 1/3

Find the equation of the line that is perpendicular to y=-2x+1 and contains the point (8, 2).

**Answer:**

y = 1/2x - 2

**Step-by-step explanation:**

In order for a line to be perpendicular to another, the lines must have opposite reciprocal slopes.

Example of an opposite reciprocal slope: -2 ⇒ 1/2

Insert the information into the point-slope formula:

[tex]y-y_1=m(x-x_1)\\\\y-2=\frac{1}{2}(x-8)\\\\y-2=\frac{1}{2}x-4\\\\y=\frac{1}{2}x-2[/tex]
