For this case we have the following polynomials:
 (9x ^ 2 + 10x + 4)

(9x ^ 2 + 5x - 1)

 Subtracting both polynomials we have:
 (9x ^ 2 + 10x + 4) - (9x ^ 2 + 5x - 1)

 We group terms with the same exponent:
 (9x ^ 2 - 9x ^ 2) + (10x - 5x) + (4 - (-1))

 Rewriting we have:
 (9x ^ 2 - 9x ^ 2) + (10x - 5x) + (4 +1)

5x + 5
 Answer:
 
The difference is given by:
 
(a) 5x + 5

Use substitution. What is the solution to the system of equations?<br><br> y=1/2x+2<br> 2y=x+4
morpeh [17]

Answer: Infinitely many solutions.

Step-by-step explanation:

y=\frac{1}{2}x+2\\2y=x+4\\

Use \frac{1}{2} x+2 for y in 2y=x+4

2(\frac{1}{2}x+2)=x+4\\x+4=x+4\\x-x = 4-4\\0=0

Infinitely many solutions.
