Answer: OPTION A
Step-by-step explanation:
 The equation of the line in slope-intercept form is:
 
 Where m is the slope and b the y-intercept.
 Solve for y from each equation:
 
 As you can see the slope and the y-intercept of each equation are equal, this means that both are the exact same line. Therefore, you can conclude that the system has infinitely many solutions.
 
        
             
        
        
        
Answer:
6. Find the product for both sets of polynomials below by multiplying vertically. (4 points: 2 points for each product)
A) 
4x^4 - 4x^3 - 16x^2 + 16x
B) 
4x^4 - 4x^3 - 16x^2 + 16x
7. Are the two products the same when you multiply them vertically? (1 point)
Yes, the two products are the same when you multiply them.
Making a Decision:
8. Who was right, Emily or Zach? Are the products the same with the three different methods of multiplication? (1 point)
Emily was right, the products are the same with all three different methods of multiplication.
9. Which of these three methods is your preferred method for multiplying polynomials? Why? (1 point)
I prefer the table method because it is easier to understand what is going on, know where and what to do, and it is nicely and neatly laid out in front of me.

Answer:
18 days 
Step-by-step explanation:
Find how many days it can be expected to rain by finding 60 percent of 30
30(0.6)
= 18
So, one can expect it to rain for a total of 18 days out of the 30 days
