Answer:

If line EF was dilated by a scale of 1/2 from the origin to get line E'F', then if line E'F' is dilated by a scale of 2 from the origin, EF is obtained. Also, the length of EF is double than the length of E'F'.

Dilation by a scale of 2 from the origin transforms point (x,y) into (2*x, 2*y)

E'(1,0) -> E(2,0)

F'(1, 3) ->F(2, 6)

length of E'F': 3

length of EF: 6

MrMuchimi
1) Which two teams had the greatest point difference?
Delta and Beta (85 - 25 = 60)

2) Which two teams had the least point difference?
Delta and Gamma (85 - 75 = 10)

3) What was the average score of the 5 teams?
(45+25+75+85+65) / 5 = 295 / 5 = 59

4) How many more points did Epsilon score than Beta?
Epsilon: 65
Beta: 25 
65 - 25 = 40
Epsilon scored 40 more than Beta

<span>5) Which teams scored more than 2 times Beta’s score?</span>
twice of Beta = 25 x 2 = 50

answer
Gamma (75) , Delta (85)  and Epsilon (65)

What is the slope of a line that passes through the origin and the point (-2,1)?
Mazyrski [523]

Answer:

<em>The slope would be</em><u><em> -1/2. </em></u>

Step-by-step explanation:

Since, the midpoint of the segment joining the points P (0, -4) and B (8, 0),

<em> = </em><u><em>( 4, -2 ), </em></u>

Now, the slope of the line passes through the origin and the point ( 4, -2) is,

= <u>-1/2</u>

  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right<u> </u>

<u>Algebra I</u>

  • Coordinates (x, y)

<u>Algebra II</u>

  • Distance Formula: \displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Step-by-step explanation:

*Note:

The distance formula is derived from the Pythagorean Theorem.

<u>Step 1: Define</u>

<em>Identify</em>

Point (5, 10)

Point (10, 12)

<u>Step 2: Find distance </u><em><u>d</u></em>

  1. Substitute in points [Distance Formula]:                                                         \displaystyle d = \sqrt{(10 - 5)^2 + (12 -10)^2}
  2. [√Radical] (Parenthesis) Subtract:                                                                   \displaystyle d = \sqrt{5^2 + 2^2}
  3. [√Radical] Evaluate exponents:                                                                       \displaystyle d = \sqrt{25 + 4}
  4. [√Radical] Add:                                                                                                  \displaystyle d = \sqrt{29}
