Answer:

D: $x^{2}$ = 576 + $7^{2}$

Step-by-step explanation:

Well you want to find what x is so you need the square root

We already have the area for one of the squares (576) which can help us find what x is.

And the bottom small square is 7 and since it's a sqaure all the sides are congruent/ same. Which means u get $7^{2}$ .

And you need to add them all up to get what x is

and is $x^{2}$ since both sides of that triangle will have the same lengths, and when u have both of those lengths its easier to find the area

Hope this helped!

How do you find the slope?

Answer:

Rise over run

Step-by-step explanation:

Take two points where you know for sure the coordinates (in this problem, you can use (2, 1.5) and the origin). Find the difference between the two y's for your run, and between your two x's for your rise. Then, put it in a fraction (it needs to be a fraction, thus the name rise over run.)

What is the inverse of the function shown

Rudiy27

Step-by-step explanation:

the down function clearly is

y = x - 5, -2 <= x <= 8

the reasons :

1. it is linear. so, we have only a form of ax+b

2. x=0 => y=-5

x=5 => y=0

so, with these 2 points alone we can see

y = ax + b

-5 = a×0 +b = b

0 = a×5 - 5

5 = a×5

1 = a

the inverse function is based on

y = x - 5

x = y + 5

now renaming the variables so that y is the result and x the input variable delivers

y = x + 5

and because the original function only delivered y- values between -7 and +3, this is also the defined domain for the inverse function.

so,

y = x + 5, -7 <= x <= +3

so, we have the points

x=-7 => y=-2

x=+3 => y=8

you need to draw the line between these 2 points with filled dots at the end points (as they are included in the function).

Which of the following is the inverse of the given function? Y=3x^5-4

lawyer [7]

$y\textrm{ }=\textrm{ }(\frac{x\textrm{ }+\textrm{ }4}{3} )^{\frac{1}{5} }$

Step-by-step explanation:

Given function $y\textrm{ }=\textrm{ }3x^{5}\textrm{ }-\textrm{ }4$

To find an inverse for any given function, which is of the form $y=f(x)$ , always swap $x$ and $y$ in the equation and try to get the form $x=f(y)$ . Now, swapping back $x$ and $y$ , we get the inverse function.
