Answer:
<u>After a 75% increase, it would become</u>
x + 75%x = x + 0.75x = x(1 + 0.75) = 1.75x
<u>After a 50% decrease, it would become</u>
1.75x - 50%(1.75x) = 1.75x - 0.5(1.75x) = 1.75x - 0.875x = 0.875x = 
Because is less than x, the new amount would be less than the original.
A) f(x) = 2 - 2x
f(0) = 2 - 2(0) = 2 - 0 = 2
f(2) = 2 - 2(2) = 2 - 4 = -2
f (4) = 2 - 2(4) = 2 - 8 = -6
b)
___________
| y = 2x - 5 | y |
________ |__
-2 | -9
-1 | -7
0 | -5
1 | -3
2 | -1

Most of the information's required for finding the perimeter of the rectangle is already given in the question. Based on those details the answer to the question can be easily determined.
Length of the rectangle in question = 11 meters
Width of the rectangle in question = 4 meters
Then
Perimeter of a rectangle = 2 ( Length + Width)
= 2 (11 + 4) meters
= 2 * 15 meters
= 30 meters
So the perimeter of the rectangle in question is 30 meters as can be seen from the above deduction.
