The digit 7 would be ten times greater than the digit 7 in number 0.9750 in any number with 7 in the tenths place, for example 
0.723
0.7669
0.775
1.7899
        
             
        
        
        
I am going to assume that the equation was supposed to be  
 
 
Answer:
It is a polynomial. It is a binomial and it has a degree of 5.
Step-by-step explanation:
A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables so 
 will be considered a polynomial.
 will be considered a polynomial.
A binomial is a polynomial with 2 terms.
The degree of a polynomial is the highest exponent in it which in this equation is 5. 
 
        
             
        
        
        
Answer:
X=-6
Step-by-step explanation:
 
        
                    
             
        
        
        
Equation 1)  4x + 2y = 8
Equation 2)  16x - y = 14
Multiply all of equation 2 by 2.
2)  2(16x - y = 14)
2)  32x - 2y = 28
1)  4x + 2y = 8
Add equations together.
36x = 36
Divide both sides by 36.
x = 1
Plug in 1 for x in the first equation.
4x + 2y = 8
4(1) + 2y = 8
4 + 2y = 8
Subtract 4 from both sides.
2y = 8 - 4
2y = 4
Divide both sides by 2.
y = 4/2
y = 2
So, x = 1, y = 2
~Hope I helped!~
