To build a fence is perimeter so 45.5 x 2=91
155 - 91=64
since that is still two sides you divide 64 by 2 and get 32.
then area is l x w so 32 x 45.5= 1456

Answer: D) h(x) = (1/4)x</h3>
This is the same as h(x) = x/4
In decimal form, it would be h(x) = 0.25x
=============================================
Explanation:
Inverses undo the original function. The original function tells us to take any input (x) and multiply by 4 to get the output y = f(x) = 4x
To get the inverse, we reverse the operation applied here. The opposite of multiplication is division. So we'll divide by 4 instead of multiply by 4. This is why the answer is x/4 or (1/4)x
-----------
Another approach is to do the following: Replace f(x) with y. Swap x and y. Solve for y
f(x) = 4x
y = 4x
x = 4y
4y = x
y = x/4
h(x) = x/4
We end up with the same result as before.

Extra info:
For any real number x, the following two equations are true
h( f(x) ) = x
f( h(x) ) = x
Answer: (x-3)(2x+1)(8)
Step-by-step explanation: First factor out the 8 to get (8)(2x^2-5x-3). So now we have what number multiply out to -6 (ab) and add up to -5. -2 and -3 work out so we manipulate the equation like (8)(2x²-2x-3x-3). Factor out 2x in the first term and -3 in the second and keep going.
Answer:
y = 12x/5 - 39/5.
Step-by-step explanation:
The equation of the straight line is given by the following formula:
(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1); where (x, y) is the general point, (x1, y1) is the first point on the line, and (x2, y2) is the second point on the line.
Given that (x1, y1) = (2, -3) and (x2, y2) = (7, 9):
(y - (-3))/(x - 2) = (9 - (-3))/(7-2).
(y + 3)/(x - 2) = 12/5.
Cross multiplying:
5*(y + 3) = 12*(x - 2).
5y + 15 = 12x - 24.
5y = 12x - 39.
y = 12x/5 - 39/5.
This the equation of the line in the y = mx + c form!!!
The answer go to be 200 and you subtract
