Solve y=x^2+23 for x

LenKa [72]

For this case we must clear x from the given equation:

$y = x ^ 2 + 23$

We passed 23 subtracting the other side of equality:

$y-23 = x ^ 2$

By definition, $a ^ 2 = b$ is written as $a = +/-\sqrt{b}$

So, we have:

$x = + / -\sqrt{(y-23)$

So, the solution of $y = x ^ 2 + 23$ for x is:

$x = + / -\sqrt{(y-23)$

Answer:

$x = + / -\sqrt{(y-23)$

$x1=+\sqrt{(y-23)$

$x2=-\sqrt{(y-23)$

Vhat is the inverse of the function f(x) = 2x – 10?

olchik [2.2K]

To find the inverse of a function, replace x and y in the equation and solve for y. In our case...

x=2y-10
x+10=2y
y=x/2+5

Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8.

Margarita [4]

If you would like to simplify Q + S - T, you can do this using the following steps:<span>

Q = 7m + 3n,
R = 11 - 2m,
S = n + 5,
T = -m - 3n + 8

</span>Q + S - T = 7m + 3n + n + 5 - (-m - 3n + 8) = 7m + 3n + n + 5 + m + 3n - 8 = 8m + 7n - 3

The correct result would be <span>8m + 7n - 3.</span>
