A) x -y =1
B) x * y =1
B) y = 1/x
A) x -(1/x) = 1
Multiplying both sides by "x"
A) x^2 -1 = x
A) x^2 -x -1 = 0
Solving by the quadratic formula
x = 1.618 and
y = .618
Interestingly, the number 1.6180339... is called the "phi ratio" or the "golden ratio".

X^1/2 - x
-2x^3 - x^1/2 - x
-2x^3 - 2x
i think this is it
Answer and Step-by-step explanation:
This problem requires the use of trigonometric functions, specifically the tangent trig function.

Plug in the values.

Multiply by x to both sides, then divide by tan(40) to both sides.

Now, plug this into a calculator and rounded to the nearest whole number (foot).
x = 9534.0287
x = 9534 ft.
The answer is 9534 ft., the last option.

Answer:
Step-by-step explanation:
<u>Solve for y:</u>
Add - 2x to both sides
- 2x + y - 2x = 7 - 2x
- y = 7 - 2x
