By our very goofy system the circle constant 
denotes half a circle, 
. So the conversion factor from radians to degrees is
Calling the rightmost dot [1] and counting counterclockwise, that's dot [4].
That's dot [6]
That's dot [12]
That's dot [14]
Answer:
x = 4, y = -3
Step-by-step explanation:
{2x - y = 11
{x + 3y = -5
You can use the substitution method by solving for x in the second equation:
x + 3y = -5
Subtract 3y from both sides:
x = -3y - 5
Now, substitute this value for x into the first equation:
2x - y = 11
2(-3y - 5) - y = 11
Distribute:
-6y - 10 - y = 11
Add 10 to both sides:
-6y - y = 21
Combine like terms:
-7y = 21
Divide both sides by -7:
y = -3
Next, substitute this value for x into the second equation:
x + 3y = -5
x + 3(-3) = -5
Multiply:
x - 9 = -5
Add 9 to both sides:
x = 4
12/x + 7 =13/x, where x is not 0;
<=> 12 + 7x = 13 <=> 7x = 1 <=> x = 1/7;
One of the many ways of writing the equations of lines is the slope - intercept form. This is generally expressed as,
y = mx + b
where m is the slope and b is the y-intercept.
Substituting the known values of m and b to the equation above,
y = -2x + 4
Thus, the answer is letter A.
<span>Two non co-linear segments with a slope of 3 in a coordinate plane would mean that the two segments are parallel to each other and not attached to each other. Having the same slope is the definition of being parallel in the same plane.</span>
