To find the angle use arc tan (-5/-7) which simplifies tips arctan(5/7). arc tan is tan to the power -1, which is also called inverse tan. The heading of the angle, if you drew this out on a graph your angle would be in the third quadrant and therefore the heading is south of west.
Answer:
The equation is;
y = 12x-41
Step-by-step explanation:
Mathematically;
slope intercept form is;
y = mx + b
where m is slope and b is intercept
Since we already have the slope , the equation is;
y = 12x + b
To get b which is the y intercept, we simply substitute the value of the points given
Thus;
19 = 5(12) + b
19 = 60+ b
b = 19-60
b = -41
So the equation is;
y = 12x - 41
Answer:
8
Explanation:
cotx – 11 = -9
To solve algebraically, try to get cotx alone.
First, add 11 to both sides:
cotx – 11
+ 11 = -9
+ 11cotx = 2
Now divide by
on both sides, which is the same as multiplying the other side by 4:
cotx ÷
= 2 ÷
cotx = 8
The Answer Is Probably, "-6" .
