Answer:
(- 1, 1 )
Step-by-step explanation:
Given the 2 equations
2x - y = - 3 → (1)
x + y = 0 → (2)
Adding the 2 equations term by term will eliminate the term in y, that is
3x = - 3 ( divide both sides by 3 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (2)
- 1 + y = 0 ( add 1 to both sides )
y = 1
Solution is (- 1, 1 )
 
        
                    
             
        
        
        
Answer:
See below
Step-by-step explanation:
We shall prove that for all 
. This tells us that 3 divides 4^n+5 with a remainder of zero.
If we let 
, then we have 
, and evidently, 
.
Assume that 
 is divisible by 
 for 
. Then, by this assumption, 
.
Now, let 
. Then:

Since 
, we may conclude, by the axiom of induction, that the property holds for all 
.
 
        
             
        
        
        
<u>Answer:</u>
The geometric mean between each pair of numbers 
<u>Solution:</u>
 The Geometric mean between two numbers a and b is given as  Geometric mean = 
   --- eqn 1
The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root for the numbers.
From question, given that two numbers are 
Hence we can say “a” = 
 =7  
Similarly “b” = 
 = 29  
We have to find the geometric mean between “7” and “29”
By using equation 1,  
Geometric mean between 7 and 29 = 
 = 14.24
Hence the geometric mean between
