Find the equation of the line passing through the points -2x+1 (8,2)
Harrizon [31]

The line that passes through (-2, 1) and (8, 2) is:

y = (1/10)*x + 12/10

<h3>How to find the equation of the line?</h3>

I assume you want to find the equation of the line that passes through (-2, 1) and (8, 2).

A general linear equation is written as:

y = a*x + b

If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope can be written as:

a = \frac{y_2 - y_1}{x_2 - x_1}

In this case, we know that it passes through (-2, 1) and (8, 2), then:

a = \frac{2 - 1}{8 - (-2)} = 1/10

Then the line is:

y = (1/10)*x + b

To find the value of b, we use one of the given points, for example if we use (8, 2), it means that when x = 8, we must have y = 2.

2 = (1/10)*8 + b

2 - 8/10  = b

20/10 - 8/10 = b

12/10 = b

Then the linear equation is:

y = (1/10)*x + 12/10

Each week, Rosario drives to an ice skating rink that is 120 miles away. The round-trip takes 2.75 hours. If he averages 55 mile
kari74 [83]
While going to the ice skating rink,
Rosario drives a distance of 55 miles in = 1 hour
Then
While going to the ice skating rink,
Rosario drives a distance of 120 miles in = (1/55) * 120 <span>                                                                                                         = 2.18 hours</span>
The number of miles per hour Rosario averages while coming back home = x Total up and down time taken by Rosario = 2.75 hours
Then time taken by Rosario to come back
home from ice skating rink = (2.75 – 2.18) hours <span>                                                     = 0.57 hours</span>
Then we can write the equation as
 x = 120/0.57 miles/hour <span>  
    = 210.53 miles/hour</span>
<span>So the average speed of Rosario while coming back home from ice skating rink is 210.53 miles per hour.</span>

The slope is -1/5 after using the formula m=rise over run. Reflected across the x-axis, the slope is 1/5 because the y coordinates become negative when reflected across x-axis.

What is the circumference of a circle with an area of 25??
Semmy [17]
Answer:  The circumference is:  " 8.87 square units " .
_________________________________________________
Explanation:
_____________________________________
Note the following:
________________________________
Area of a circle:  A = π r² = 25 units² ; 
 
Circumference of a circle:  C = π*d = 2πr
____________________________________
  If we can solve for "r" ("radius", we can solve for the "Circumference, "C") ;
__________________________________
   A = π r² = 25 ;

    C = 2 * π *r
 
   So:  " π * r * r = 25"  ;
________________________
 We know that:  " π * r * r = 25" ; 

Multiply EACH side of the equation by "2" ; 
__________________________________
      2*{ π * r * r = 25} ;
__________________________________
To get:  2 * π * r * r = 25 ; 

Note:  "C = 2* π * r ; 

So,  "(2 * π * r) * r = 25 " ; 

We want to solve for "C" ; so replace the "(2 * π * r) " ; with "C" ;
 
          C * r = 25 ; 
______________________________
Divide EACH SIDE of the equation by "r" ; to isolate "C" on one side of the equation:
________________________________
   (C * r) / r  =  25 / r   ;

to get:    C  =  25 / r ;  
____________________________________
Now, we need to find the value for "r" (the radius);
          to find "C" (the circumference).

We know that:  
____________________________________ 
   π * r² = 25 ;
____________________________________
Divide each side of the equation by "π"; to isolate "r² " on one side of the equation;
____________________________________
   (π * r²) / π  =  25 / π ;

To get:  
___________________________________________________
   r²  =  25/π  ;  Let us use "3.14" as an approximation for "π" ;
___________________________________________________
   r²  =  25 / (3.14) ; 
  
   r²  =  7.9617834394904459 ; 

Take the "positive" square root of EACH side of the equation; 
   (since the radius, "r", cannot be a negative value);
_____________________________________________

   +√(r²) = +√(7.9617834394904459) ; 
_____________________________________________
to get:
_____________________________________________
      r  =  2.8216632399155016635 ;  
              →  Round to:  " 2.82 " ; 
_____________________________________________
     C = 25 / r  ;
 
     C = 25 / (2.82) = 8.8652482269503546  square units .
                              →  Round to:  "8.87"  square units.
_____________________________________________
The answer is:  "8.87 square units" .
