<u>Answer:</u>

$\frac { 4 } { 5 }$

<u>Step-by-step explanation:</u>

We are given the following two points and we are to find the slope of the line which passes through these points:

$(3.-1)$ and $(-2,-5)$

The formula of the slope is given by:

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

Substituting the given coordinates in the above formula:

Slope = $\frac { - 5 - ( - 1 ) } { - 2 - 3 } = \frac { 4 } { 5 }$

NEED HELP WITH THIS PROBLEM!!!!!!

zzz [600]

Answer:

$\displaystyle\frac{\sqrt[4]{3x^2}}{2y}$

Step-by-step explanation:

It can work well to identify 4th powers under the radical, then remove them.

$\displaystyle\sqrt[4]{\frac{24x^6y}{128x^4y^5}}=\sqrt[4]{\frac{3x^2}{16y^4}}=\sqrt[4]{\frac{3x^2}{(2y)^4}}\\\\=\frac{\sqrt[4]{3x^2}}{2y}$

_____

The applicable rules of exponents are ...

1/a^b = a^-b

(a^b)(a^c) = a^(b+c)

The x-factors simplify as ...

x^6/x^4 = x^(6-4) = x^2

The y-factors simplify as ...

y/y^5 = 1/y^(5-1) = 1/y^4

The constant factors simplify in the usual way:

24/128 = (8·3)/(8·16) = 3/16

Graph the function represented in the table on the coordinate plane.

Umnica [9.8K]

First find out the function for the given table.
Find the slope.
m= (y2-y1)/(x2-x1)
m=(-1-(-3)) / (-1-(-2))
m=(-1+3) / (-1+2)
m=2/1
m=2
Now equation of line:
y-y1=m(x-x1)
y-(-3)=2(x-(-2))
y+3=2(x+2)
y+3=2x+4
y=2x+1
Now plot these points on the graph, we get the attached graph.
