Answer:
Step-by-step explanation:
In order to write the equation of the line in point-slope form that goes through those points, we need to know the slope of that line. Therefore,
So the slope is 2. Now we'll pick a point and use it to write an equation in point-slope form. I'll use the first point given to see if that's the one used in any of the answers : (10, 5)
y - 5 = 2(x - 10). That's choice B. Let's see, just in case there are 2 answers to this, what the equation would be using the other point (4, -7):
y - (-7) = 2(x - 4) and simplified:
y + 7 = 2(x - 4) is the other equation. Since that's not a choice, the only answer is B
Answer:
Change the equation to the slope intercept form (y = mx + b)
2y = 6x + 8
Divide equation by 2
y = 3x + 4
Therefore
The line as a y intercept of 4
:
Parallel lines have the same slope;
Find the slope by putting in the equation in the point/intercept form
4x + 4y = 20
4y = -4x + 20
Divide equation by 4, results
y = -1x + 5
:
Now we know the slope (-1) and the y intercept (+4) if the line
y = -1x + 4
or just
y = -x + 4 is "the line"
Step-by-step explanation:
For this case we must find the perimeter of the fence, in a circular way, knowing that the perimeter of a circle is given by:
Where "r" represents the radius of the circle, in this case 
Substituting in the perimeter equation we have:
Rationalizing we have:
Taking out common factor 
:
Answer:
Option C
What you are trying to solve is 4000 divided by 4 which is 1000
