Answer:
I personally don't know how to answer.. but it wants you to write the answer in function notation.
For example ^: 2^7: 2x2x2x2x2x2x2

Answer:

Step-by-step explanation:
The standard equation of a circle is given by: 

Where (<em>h, k</em>) is the center and <em>r</em> is the radius. 
We are given that the center is (4, -7) and that the radius is √(43). 
So, <em>h</em> = 4, <em>k</em> = -7, and <em>r</em> = √(43). Substitute: 

Simplify. Hence, our equation is: 

 
        
             
        
        
        
Answer:
a = 15
b = -10
Step-by-step explanation:
Here, we want to solve the system of linear equations 
Firstly, let us multiply the first equation through by 10
2a - 5b = 100 ••••(i)
from the second equation;
a = 29 + b
Substitute this into i
2(29 + b) - 5b = 100
58 + 2b -5b = 100
-3b = 100-58
3b = 42
-b = 42/3
-b = 14
recall;
a - b = 29
a - (-14) = 29
a + 14 = 29
a = 29-14 = 15
