the percentage decrease is
(9/20)*100
=9*100/20
=9*5
=45%

Answer:
(b) Function B
Step-by-step explanation:
The exponent of 2 in Function B tells you it is nonlinear. A linear function will not have any product of variables or any roots.
You know function A is linear because the differences in x-values are all the same, and the differences in y-values are all the same. What makes it linear is that the ratio of y-differences to x-differences is a constant:
Δy/Δx = (8 -10)/(2 -0) = -1 = (6 -8)/(4 -2) = (4 -6)/(6 -4)
__
Function B is nonlinear.
Answer:
Width = 3.75 feet
Length = 9.75 feet
Step-by-step explanation:
Given:
Length of fencing = 27 feet
Find:
Dimensions of the garden
Computation:
Assume
Width = x
So,
Length = x + 6
2(L+B) = Perimeter
2(x + x + 6) = 27
2(2x + 6) = 27
4x + 12 = 27
4x = 15
x = 3.75
Width = 3.75 feet
Length = 3.75 + 6 = 9.75 feet
Y-4=5x+10 is the simplified version of this equation
