School Mascot Votes
For topic 3 lesson 3-2 use the graph at the right.

12. The students voted on a school mascot.
Which mascot had as many votes as 4 times
the number of votes for the unicorn?
120
100
Dragon
Number of Votes
80
60
13. Explain how you could estimate the
number of students who voted on a
school mascot. Then give your estimate.
39 unicorn
22 Owl
44 Bear
78 Lion
159 Dragon
Mascot

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

i think the answer would be c

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
