Answer:
b
-28/9
Step-by-step explanation:
5+9b-23
5+9b=-23
9b=-28
b=-28/9
Answer:
Because it is a rectangle, the area is expressed as A = xy, or length times width.
Because it is next to the river, he only needs to fence three sides, so F = x + 2y.
Knowing the amount of fencing available is 7500m, we get:
7500 = x + 2y solve for x
x = 7500 - 2y substitute into the area equation
A = (7500 - 2y)y distribute
A = -2y2 +7500y
You can see that this is a parabola which opens down, meaning that the point of maximum area will be at the vertex, y = -b/2a = -7500/[2(-2)] = 1875
x = 7500 - 2(1875) = 3750
A = 3750(1875) = 7,031,250 m2

Hey there! :)
Answer:
y = 0, also known as the x-axis.
Step-by-step explanation:
The equation 
is an exponential function.
There is an asymptote at y = 0, or the x-axis because:
An exponential function, unless containing a vertical shift, can never cross the x-axis resulting in an asymptote at y = 0.
Answer: It should be y=2x-2

Answer:
252 in²
Step-by-step explanation:
The figure can be considered as a rectangle with the rectangle on the right to be added on and the rectangle on the left to be subtracted.
Area of rectangle with length 12 and width 15 + 6 = 21 is
A = length × width = 12 × 21 = 252 in²
Since the areas of the 2 rectangles to be added / subtracted are equal
both 6 × 3 = 18 in² , then they can be ignored
Then area of figure = 252 in²
