Can someone make me a word problem for 9 x (13 + 6 - 7)? I'm bad at making word problems.

Rina8888 [55]

Celia is making cookies for her neighborhood. She plans to make 9 batches of 13 cookies, but she makes more cookie dough than she planned to and adds 6 cookies to each batch. After they bake, she takes them out of the oven and takes 7 cookies from each tray to keep for herself. How many cookies will be left to distribute among her neighbors?

Hope this helps!

What is the inverse of this function? f(x)=-1/2 square root of x+3, x > -3

yuradex [85]

The inverse function of $f(x) = -\frac 12\sqrt{x + 3}$ is $f^{-1}(x) = 4x^2- 3$

<h3>How to determine the inverse function?</h3>

The function is given as:

$f(x) = -\frac 12\sqrt{x + 3}$

Rewrite as;

$y = -\frac 12\sqrt{x + 3}$

Swap the positions of x and y

$x = -\frac 12\sqrt{y + 3}$

Multiply through by -2

$-2x = \sqrt{y + 3}$

Square both sides

4x^2 = y + 3

Subtract 3 from both sides

y = 4x^2 - 3

Express as an inverse function

$f^{-1}(x) = 4x^2- 3$

Hence, the inverse function of $f(x) = -\frac 12\sqrt{x + 3}$ is $f^{-1}(x) = 4x^2- 3$

Determine if the function is an even function, an odd function or neither. > = −6x² – 5x² −2 even neither odd

mel-nik [20]

Answer: even

Step-by-step explanation:

A function is even if f(x)=f(-x), and odd if f(x)=-f(-x). If a function satisfies neither of these, it is neither even nor odd.

$f(x)_=-6x^{2}-5x^{2}-2=-11x^{2}-2\\\\f(-x)=-11(-x)^{2}-2=-11x^{2}-2\\\\\therefore f(x)=f(-x)$

Therefore, the function is <u>even</u>.
