Answer:
4x^2+6x+2
Step-by-step explanation:
Answer:
Let x rep the lenght of the shorter one
Then the longer one is 2x+1
Therefore
(2x+1) + x = 16
We now solve for x
2x + 1 + x = 16
Group and evaluate like terms
3x +1 = 16
3x = 16 -1
× = 15/3
x = 5
So the shorter one is 5 ft
The longer one is 2(5)+1= 11
Step-by-step explanation:
4x -y =2
-y = -4x + 2
y = 4x -2
slope = 4
perpendicular slope is negative inverse
so -1/4
y- -2 = -1/4(x - 4)
y+2 = -1/4x +1
y = -1/4x -1
Answer:
Average rate of change = 0.1313 or 13.13% (approx.)
Step-by-step explanation:
Given:
Pedestrian fatalities in 2006 = 4,795
Pedestrian fatalities in 2009 = 4,165
Find:
Average rate of change
Computation:
Average rate of change = [4,165-4,795] / 4,795
Average rate of change = [-630] / 4,795
Average rate of change = 0.1313 or 13.13% (approx.)
