Answer:
Step-by-step explanation:
As the description of the statement is:
'<em>Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26'.</em>
<em />
As
- <em>Five times the sum of a number and 27 </em>is written as:
- <em>greater than or equal </em>is written as:
- <em>six times the sum of that number and 26' </em>is written as: 6(x + 26)
so lets combine the whole statement:

The answer is :
EXPLANATION :
Note that cotangent is only positive when the angle is in the first or third quadrant.
Since y is not in the first quadrant, it must be in the third quadrant.
So the x and y are both negative.
An angle with a terminal point (x, y)
The cotangent is x/y
We can equate :
Since x and y are both negatives, x = -9 and y = -13
We can have the triangle :
The hypotenuse will be :
We are asked to find the value of sec y.
In an angle with a terminal point (x, y)
The secant is :
The hypotenuse is 5√10 and x = -9
The value of sec will be :
