Answer:
7n-6=-20
Step-by-step explanation:
six less than seven times a number
we'll use n as "the number" 
six less meaning -6
7 times a number n = 7n
7n-6=-20

Answer:  95 degrees</h3>
=======================================================
Explanation:
I recommend drawing it out to see what's going on. See the drawing below.
In the diagram, both angles are in the northeast corner of their four-corner configurations. They are both congruent corresponding angles. So that's why the second angle is also 95 degrees. 
Side note: we could replace "northeast" with any of the other directions on the compass (such as southwest). All that matters is that they are in the same configuration.
 
        
        
        
The value of f(0) is -1
<h3>What is a function?</h3>
A function can be defined as an expression, law or rule that explains the relationship between two variables; a dependent and an independent variable.
Given the function;
 f(x)= -x - 1
To determine f(0), we substitute the value of x as 0 in the function
So, we have;
f(0) = -(0) - 1
f(0) = -0 - 1
f(0) = -1
Thus, the value of f(0) is -1
