Answer:
B.
Step-by-step explanation:
The lines positioning shows a negative slope already, so it cant be C or D
Slope is a rise over run basis. You can check this just from points alone, the line would be much steeper if the slope was -2.
Hope this helps!
Answer:
The degree of the function is;

Explanation:
From the given graph, we can observe that the function has two extremum (one minima and one maxima).
The degree of the function will be the number of extremum plus 1;

Since there are two extremum on the graph then;

Therefore, the degree of the function is;
Answer:
13
Step-by-step explanation:
Well, the very first thing you need to do is to <span> find the slope of the line
According to the fact that we already know that the slope is parallel </span>to the line, you can easily find out the slope, to be more exact :

Straight after, you have to use <span>point slope formula</span>
Answer:
Step-by-step explanation:
A binary string with 2n+1 number of zeros, then you can get a binary string with 2n(+1)+1 = 2n+3 number of zeros either by adding 2 zeros or 2 1's at any of the available 2n+2 positions. Way of making each of these two choices are (2n+2)22. So, basically if b2n+12n+1 is the number of binary string with 2n+1 zeros then your
b2n+32n+3 = 2 (2n+2)22 b2n+12n+1
your second case is basically the fact that if you have string of length n ending with zero than you can the string of length n+1 ending with zero by:
1. Either placing a 1 in available n places (because you can't place it at the end)
2. or by placing a zero in available n+1 places.
