Answer:
K' (-1,10)
L'(0,4)
M'(2,2)
Step-by-step explanation:
To use the mapping rule, substitute x and y with the original values
The coordinates of K are x=-4, and y=5.
Using the mapping rule, x of K' = -4+3 = -1
Using the mapping rule y of K' = 2x5=10
So K' is at the coordinate (-1,10)
The coordinates of L are x =-3, and y =2.
Using the mapping rule, x of L' = -3+3=0
Using the mapping rule y of L' = 2x2=4
So L' is at the coordinate (0,4)
The coorindates of M are x=-1 and y=1
Using the mapping rule, x of M' = -1+3=2
Using the mapping rule, y of M' = 2x1 = 2
So M' is at the coordinate (2,2).
12 as 12 is divisible by 4 but not divisible by 8
Let’s first cut/separate this figure into two shapes: rectangle and a triangle
The area of the rectangle: 9 • 2 = 18
The area of the triangle: 1/2 • 8 • 4 = 16
The total area: 18 + 16 = 34
He needs 34 m square of grass
If there are n rows
And if each row has m seats.
Then the total number of seats shall be n × m.
Here
Number of rows = (c+8)
And number of seats in each row = (4c-1)
Using the concept
Total number of seats
= (c+8)(4c-1)
FOILing or Distributing we get
= c(4c) + c (-1) + 8(4c) +8 (-1)
= 4c² - c + 32 c -8
Combining like terms
=4c² +31c - 8
The expression for total number of seats = 4c² + 31c -8
