<span>2(2x-5)=3x+10-20
4x - 10 = 3x - 10
4x - 3x = -10 + 10
x = 0</span>
The given function is,
.
Or,
To find the inverse of a function, first step is to switch x and y. Therefore,
Next stpe is to solve the above equation for y t get the inverse f f(x). Hence, multiply each sides by y + 5 to get rid of fraction form. So,
xy + 5x = 2y - 1
xy = 2y - 1 - 5x Subtract 5x from each sides to isolate y.
xy - 2y = -5x - 1 Subtract 2y from each sides.
y(x - 2) = -5x -1 Take out the common factor y.
Divide each sides by x-2.
So,
Now when we will compare with then we will get a = -5, b = -1, c = 1 and d=-2
So,
Hope this helps you!

Answer: a. 164 u²</h2>
Step-by-step explanation:
Area of a trapezium = ¹/₂ (a + b) h
But the height isn't given. So we have to solve for it.
h = √(10² - 6²) <em> [using the Pythagorean theorem]</em>
<em> </em> = 8
∴ Area of the shape = ¹/₂ (13 + 28) 8
= 164 u²
Imagine you're at origin when you saw another trial 45 degrees from your trail
so the correct answer is the answer is arctan(cos(45)tan(10))
