If we were to draw a best fit line, the y-interest would be near 15, and the slope would be negative.

In the options given, the slope is either -3 or -13. If we imagine a line through the plotted points, the rise would be about 15 while the run would be about 5. This means the slope is about -3.

The best answer is y = -3x + 15

What is the inverse of the function f(x) = 2x + 1?

BaLLatris [955]

Answer:

$f^{-1} = \frac{x-1}{2}$

Step-by-step explanation:

$f(x) = 2x+1$

<em>Replace it with y</em>

$y = 2x+1$

<em>Exchange the values of x and y</em>

$x = 2y+1$

<em>Solve for y</em>

$x = 2y+1$

<em>Subtracting 1 from both sides</em>

$2y = x-1$

<em>Dividing both sides by 2</em>

$y = \frac{x-1}{2}$

<em>Replace it by </em> $f^{-1}$

So,

$f^{-1} = \frac{x-1}{2}$

The prism below is made of cubes which measure 1/3 of an inch on one side what is the volume

EastWind [94]

Answer:

Volume of rectangular prism = 10/9 inch³

Step-by-step explanation:

Given:

Size of each cube = 1/3 inch

Find:

Volume of rectangular prism

Computation:

Length of rectangular prism = 2 x [1/3]

Length of rectangular prism = 2/3 inch

Width of rectangular prism = 3 x [1/3]

Width of rectangular prism = 3/3

Width of rectangular prism = 1 inch

Height of rectangular prism = 5 x [1/3]

Height of rectangular prism = 5/3 inch

Volume of rectangular prism = Length x Width X Height

Volume of rectangular prism = [2/3] x [1] x [5/3]

Volume of rectangular prism = 10/9 inch³
