Answer:

x = 60.5

Step-by-step explanation:

ok this simple you already have the variable and the number on different sides

x2 = 121

divide each side by 2

x2 / 2 = x

121 / 2 = 60.5

x = 60.5

The function f(x) = −x2 + 50x − 264 models the profit, in dollars, a yoga studio makes for selling monthly memberships, where x
Marina CMI [18]
The given function is f(x) = -x^2 + 50x - 264. This is a quadratic function because the degree of the polynomial, the variable with the highest exponent, is 2.

All quadratic functions can be expressed in the form f(x) = ax^2 + bx + c.
In your equation,
a = -1
b = 50
c = -264

The equation for the x-coordinate vertex of a quadratic function is x =  \frac{-b}{2a}.
Applying this to the given function,
x =  \frac{-(50)}{2(-1)} =  \frac{50}{2} = 25.

Now plug the value of x into f(x) to find f(x) (aka the y-coordinate).
f(x) = -x^2 + 50x - 264 \\
f(25) = -(25)^2 + 50(25) - 264 \\
f(25) = 361

The vertex is (25, 361)

Part B
The x-intercept is where the graph crosses the x-axis. Therefore, f(x) (aka the y-coordinate) will be 0. So the x-intercept will be in the form of (x, 0).

To find the x-intercept, set f(x) = 0.
0 = -x^2 + 50x - 264 \\
0 = (x-6)(x-44) \\
x = 6, x = 44.

Therefore the x-intercepts will be at (6, 0) and (44, 0)
