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" . 
___________________________________________________<span>

Explanation:
______________________________________________
Given:

    h(x) = - 3x</span>² <span>+ 30 + 225  ;  

Rewrite as:  "  </span>- 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 <span>− 225 = 0" ; 

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

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

{</span>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:  

       " - 3x² + 30 + 225 = 0 " ; 

which is ultimately simplified to:

        " x² − 10 − 75  = 0 " .

The number of days is:  "15 days" .
