Answer:
<h2>The option B and D are the equations.</h2>
Step-by-step explanation:
Let, the total number of students are x.
The number of students having the ticket is .
It is given that the number is 20.
Hence, .
Option B is the equation.
Option D is also the same.
The difference is just, the variable is wriiten in the other side.
QUESTION 1: (2, -3) and (5, -4)
<u>Y2 -Y1</u>
X2 -X1
<u>-4 - -3</u>
5 - 2
= - <u>1</u>
3
QUESTION 2: (3, -4) Slope = 6
About Point Slope Form:
- Y -Y1 = m (x - X1)
- m is the slope
- Y1 & X1 is a point on the line
- The form allows you to identify the slope & the point on the line
Y - -4 = 6 (x - 3)
a) The image is a reduction because it is simply <em>smaller</em> than the original.
b) We can find the scale factor by finding the<em> ratio of the side length of the new triangle compared to the original one</em>.
MS = 6 - (-3) = 6 + 3 = <em>9 units</em>
M'S' = 4 - (-2) = 4 + 2 = <em>6 units</em>
(Easiest to calculate because they are horizontal lines)
6 : 9 = 2 : 3 = 2/3 = 2 to 3
