Hello There!

It would be x².
The question is x³/x.
X with no power is x to the power of one.
When dividing powers you subtract them.
3 - 1 = 2,
Therefore, making your answer x²

Hope This Helps You!
Good Luck :)

Assuming X3 means x cubed, x3/x equals x squared, with the restriction that x cannot equal 0

Maggie makes and sells scented body lotions. She initially spent 108 to purchase supplies, and each kilogram of lotion cost 16 t

slamgirl [31]

Answer:

12 kilograms

Step-by-step explanation:

Let's construct an equation for her profits, we will call it P(x), where x is the number of kilograms produced/sold.

We know she has -$108 profit from buying supplies, and for each kilogram she produces, she earns -$16 (or loses $16, if earning negative money bothers you). However, we also know that she earns $25 per kilogram sold.

Constructing the equation with this information, we get: $P(x)=25x-16x-108=9x-108$

Setting this equation to zero and solving for x:

$9x-108=0$

$9x=108$

$x=12$

If f(x) = square root of x+3, what is the equation for f–1(x)? f–1(x) = x2 - 3 f–1(x) = x2 + 3 f–1(x) = (x - 3) 2 f–1(x) = (x +

Answer:

$\Large \boxed{\sf \ \ f^{-1}(x)=x^2-3 \ \ }$

Step-by-step explanation:

Hello,

$\text{For }x+3\geq 0\\\\f(x)=\sqrt{x+3}\\\\x=(fof^{-1})(x)=f(f^{-1}(x))=\sqrt{f^{-1}(x)+3}\\\\\text{*** take the square ***}\\\\f^{-1}(x)+3=x^2\\\\\text{*** subtract 3 from both sides ***}\\\\\large \boxed{\sf \ \ f^{-1}(x)=x^2-3 \ \ }\\$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
