Solve for r in terms of s, t, and u. <br> t=u-s+r

Verdich [7]

Answer:

r = t - u - s

Step-by-step explanation:

To solve for r in terms of s, t, and u, means to have r on one side and have t, u, and s.

t = u - s + r

t - u = s + r

t - u - s = r

Identify the inverse of the following.

posledela

Answer:

$f^{-1}(x)=\sqrt{\frac{1}{8}(-x+4)}$

Step-by-step explanation:

Given function is,

f(x) = -8x² + 4

Step to find the inverse of the function,

Step 1

Write the function in the form of an equation,

y = -8x² + 4

Step 2

Interchange the variables 'x' and 'y',

x = -8y² + 4

Step 3

Solve the equation for y,

x = -8y² + 4

x - 4 = -8y²

-x + 4 = 8y²

y² = $\frac{1}{8}(-x+4)$

$y=\sqrt{\frac{1}{8}(-x+4)}$

Therefore, inverse of the function f(x) will be,

$f^{-1}(x)=\sqrt{\frac{1}{8}(-x+4)}$
