Hey there,
Let's remember that a (inequality symbol) is things like (<), (>), (≤),(≥), (≠).
So, I believe that (-3x+7) and (-10-2) are separate. So we will find that out :)
Let's first do (-3x+7). As simplifying this expression here, we take that "x" of for a while and just stick to (-3+7).
-3
+ 7
______
4
Let's bring that "x" back, and the answer would be 4x for a while.
So far, 4x is the answer.

Now, Let's work on the other side.
We are talking about (<span>-10-2)
-10
- 2
_______
</span> -12
So, by solving the answer to (-10-2), we got -12.
So, let's determine what is greater . . . . .
-12 or 4.
-12 is on the negative side, and the number 4 is positive. This would conclude that 4 is great than -12.
Your correct answer would look like . . .
<span>(-3x+7) > (-10-2)
</span>
I really hope this helps you alot.

Answer:
Value of
Step-by-step explanation:
Given: A vertical line is dropped from the x-axis to the point (12, -9) as shown in the diagram below;
To find the value of .
By definition of secants;
Now, first find the cosine of angle
As the point (12 , -9) lies in the IV quadrant , where
Consider a right angle triangle;
here, Adjacent side = 12 units and Opposite side = -9 units
Using Pythagoras theorem;
or
Cosine ratio is defined as in a right angle triangle, the ratio of adjacent side to hypotenuse side.
then;
and
therefore, the value of is,
