Answer:
Step-by-step explanation:
(a,9).......we dont know " a " (or x) but we do know y...it is 9
so sub in 9 for y and solve for x
y = 2x + 1
9 = 2x + 1
9 - 1 = 2x
8 = 2x
8/2 = x
4 = x <======= ur answer is D

where 
is a proportional constant.
Given that, when 
, then 
Plugging these values into the above equation, we will get.....
Now plugging this 
into equation (1).....
So, the function to represent this relationship will be:
Answer:
Step-by-step explanation:
You can find the area by cutting it across in the middle into a trapezoid and a rectangle.
The trapezoid will have:
height = 10-4 = 6ft
top = 9-6 = 3ft
bottom = 8ft
So its area = 1/2*(3+8)*6 = 33 ft^2
The rectangle will have:
length = 10ft
width = 6ft
So its area = 10*6 = 60 ft^2
Total area = 60+33 = 93 ft^2
