Two parallel line segments move from Quadrant One to Quadrant Four. Their slopes does not change.

pishuonlain [190]

Answer:

Step-by-step explanation:

Dilation is changing it and it would not move Quadrants. Reflection would change the slope and I do not know if you can even do it from one to four (I also don't know which one is 1 and which one is 4).

All I know is that translation moves it without changing anything. It is a transformation bc it is translation.

What is the inverse of this function? (Function in photo)

valkas [14]

Given:

The function is

$f(x)=-\dfrac{1}{2}\sqrt{x+3},x\geq -3$

To find:

The inverse of the given function.

Solution:

We have,

$f(x)=-\dfrac{1}{2}\sqrt{x+3}$

Put f(x)=y.

$y=-\dfrac{1}{2}\sqrt{x+3}$

Interchange x and y.

$x=-\dfrac{1}{2}\sqrt{y+3}$

Isolate the variable y.

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

$(-2x)^2=y+3$

$4x^2-3=y$

$y=4x^2-3$

Putting $y=f^{-1}(x)$ , we get

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

For $x\geq -3$ ,

$x+3\geq 0$

$\sqrt{x+3}\geq 0$

$-\dfrac{1}{2}\sqrt{x+3}\leq 0$

$f(x)\leq 0$

It means for function $f(x)\leq 0$ and for inverse function $x\leq 0$ because the range of the function is the domain of inverse function.

Therefore, $f^{-1}(x)=4x^2-3$ for $x\leq 0$ .

Lexi and her mom are volunteering at an emergency relief center. To help prepare in case of a flood, they pack emergency kits wi

GenaCL600 [577]

The equation that can be used to find the number of emergency kits that Lexi packs is 4x=120.

Given that Lexi packs 4 water bottles into each kit and total 120 water bottles are packed by Lexi.

We are required to find the equation which can be used to find the number of emergency kits that Lexi packs.

Equation is like a relationship between two or more variables that are expressed in equal to form.Equation of two variables look like ax+by=c. It may be linear equation,quadratic equation, cubic equation and many more depending on the power of the variable that is present in that equation.

let the number of emergency kits that Lessi packs be x.

The equation which will shows the total number of bottles be:

=(Number of bottles in 1 kit)*x

Equation will be:

4x=120

Hence the equation that can be used to find the number of emergency kits that Lexi packs is 4x=120.
