Plot the points (2, 5), (2, -4), (10, 5), and (10, -4) on a coordinate plane. What is the perimeter of this polygon?

How do u graph 2y=-4x+6

gladu [14]

Answer:

3 would be your y intercept

then from the point 0,0 put 2 in as slope

Step-by-step explanation:

First turn the equation into y=mx+b (slope-intercept form)

Which turns into y= -2x+3

in y=mx+b

m is slope and b is y intercept

3 would be your y intercept

then from the point 0,0 put 2 in as slope

For the right triangle shown, the lengths of two sides are given. Find the third side. Leave your answer in simplified, radical

sleet_krkn [62]

Answer: $c=4\sqrt{2}$

Step-by-step explanation:

For this exercise you need to apply the Pythagorean Theorem. This is:

$h^2=l^2+m^2$

Where "h" is the hypotenuse of the Right triangle and "l" and "m" are the legs.

In this case, you can identify that:

$h=c\\\\l=a=4\\\\m=b=4$

Knowing these values, you can substitute them into $h^2=l^2+m^2$ :

$c^2=4^2+4^2$

Now you must solve for "c":

$c=\sqrt{4^2+4^2}$

Evaluating, you get:

$c=\sqrt{16+16}\\\\c=\sqrt{32}$

To simplify the result:

- Descompose 32 into its prime factors:

$32=2*2*2*2*2=2^5$

- By the Product of powers property, you know that:

$2^5=2^4*2$

- Make the substitution:

$c=\sqrt{2^4*2}$

- Finally, knowing that $\sqrt[n]{a^n}=a$ , you get:

$c=2^2\sqrt{2}\\\\c=4\sqrt{2}$

Guys, I really need help!

TiliK225 [7]

Answer:

The answer is

$p = \frac{ - 3}{1000} n + 97$

Step-by-step explanation:

We have the points (2000,91) and (5000,82)

Then

$m = \frac{91 - 82}{2000 - 5000} = \frac{ - 3}{1000} \\ to \: find \: the \: b \\ 91 = \frac{ - 3}{1000} \times 2000 + b \\ b = 97 \\ then \: the \: equation \: is \: \\ p = \frac{ - 3}{1000} n + 97$

The number of horses occupying stalls at the county fairgrounds can be modeled by the following function, where x represents the

Elenna [48]

Answer:
_______________________________________________________
The rewritten equation is:

" - 3x² + 30 + 225 = 0 " ;

which is ultimately simplified to:

" x² − 10 − 75 = 0 " .
___________________________________________________
The number of days is: "15 days" .
___________________________________________________

Explanation:
______________________________________________
Given:

h(x) = - 3x² + 30 + 225 ;

Rewrite as: " - 3x² + 30 + 225 = 0 " ;
__________________________________________________________
Multiply EACH SIDE of the equation by "-1" ; to get rid of the "-3" ;

-1 * {- 3x² + 30 + 225 = 0} ;

to get: " 3x² − 30 − 225 = 0" ;

Divide EACH SIDE of the equation by "3" ; to simplify; since:

"3", "30", and "225" are divisible by "3" ;

{3x² − 30 − 225} / 3 = 0 / 3 ;

to get:
______________________________________
" x² − 10 − 75 = 0 " ;

______________________________________
Let us factor:

-15 + 5 = -10 ;

-15 * 5 = -75 ;
_______________________________________
Rewrite as:

(x − 15) (x + 5) = 0 ;

x = 15; and x = -5 ;
_______________________________________
The number of days cannot be "negative value"; so we stick with:

"x = 15 days"

Answer: The rewritten equation is:
