Answer:
The slope of the line passing through the points (-4, 8) and (2,8) is 0
Step-by-step explanation:
The slope is 0 because you would subtract the y ones first 8-8, subtract the x ones next 2-(-4). You would get 0/6. When you would divide 0/6, you would get 0
<em>Answer:</em>
<h3>
<em>B'=</em><em>(</em><em>1</em><em>6</em><em>,</em><em>1</em><em>4</em><em>)</em></h3>
<em>It </em><em>is </em><em>clear </em><em>from </em><em>the </em><em>co-ordinates</em><em> </em><em>of </em><em>the </em><em>square </em><em>that </em><em>CD </em><em>is </em><em>parallel </em><em>to </em><em>X </em><em>axis </em><em>and </em><em>BC </em><em>is </em><em>parallel </em><em>to </em><em>y-axis.</em><em> </em><em>So,</em><em>X=</em><em>8</em><em>,</em><em>y=</em><em>7</em>
<em>so </em><em>the </em><em>co-ordinates</em><em> </em><em>of </em><em>B=</em><em>(</em><em>8</em><em>,</em><em>7</em><em>)</em>
<em>Now </em><em>after </em><em>dilation</em><em> </em><em>of </em><em>factor </em><em>2</em><em>,</em><em> </em><em>all </em><em>coordinates</em><em> </em><em>will </em><em>be </em><em>multiplied</em><em> </em><em>by</em><em> </em><em>2</em><em>.</em>
<em>So </em><em>B'=</em><em>(</em><em>1</em><em>6</em><em>,</em><em>1</em><em>4</em><em>)</em>

Question 1:
------------------------
Total points = 100
Total question = 40
Type of questions : 2-points question and 4-points questions
Assumed all 40 questions are 2-points questions.
Total points = 40 x 2 = 80
Difference in points = 100 - 80 = 20 points
Difference in the 2 type of questions = 4 - 2 = 2
Number of 4 marks questions = 20 ÷ 2 = 10
Number of 2 marks questions = 40 - 10 = 30
Answer: There are 10 4-marks questions and 30 2-marks questions.
------------------------------------------------------------------------------------------------
Question 2:
------------------------
Let x be the number of offices you need to clean.
Total cost = 315 + 4x
Total revenue = 25x
To break even,
315 + 4x = 25x
21x = 315
x = 15
Answer: You need to clean 15 offices to break even.
------------------------------------------------------------------------------------------------
Question 3:
------------------------
Total distance (including return trip) = 255 + 255 = 510 miles
Total time taken = 1.7 + 1.5 = 3.2 hours
Speed = Distance ÷ time
Speed = 510 ÷ 3.2 = 159.38 miles/hour
Answer: The average speed is 159.38 miles/hour
It means your taking money out of your bank of pay check every Week
F(x) = 3x-6
g(x) = x-2
so f/g = 3(x-2)/(x-2) = 3
