Answer:

Step-by-step explanation:
So first thing is that slope intercept form is setup like this 
y=mx+b
m=slope
b=y intercept 
the slope is change in y over change in x 
as y goes down 2 x goes up 5
so the slope is -2/5
the y intercept is at (0,-1) so the y intercept is -1
therefore the answer is 

have a great day :)
 
        
                    
             
        
        
        
Answer:
140
Step-by-step explanation:
20+4(s)=
20+4(30)=
20+ 120=
140
 
        
             
        
        
        
The <em>correct answer</em> is:
400,000.
Explanation:
The third digit in 399 is 9. To round to this place value, we inspect the digit behind it. If the digit is 5 or greater, we round up; if it is less than 5, we round down.
The digit behind 9 is 7. Since it is greater than 5, we round up. This would ordinarily put the number up 1; however, doing that makes the 9 a 10, which in turn makes the next number 10, and the next number 4. This gives us 400,000.
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
The general form of a quadratic polynomial is given by:
 (1)
    (1)
You have the following polynomial:
 (2)
    (2)
In order to complete the factorization you can use the quadratic formula, to obtain the roost of the polynomial. The quadratic formula is given by:
 (3)
    (3)
By comparing the equation (1) with the equation (2) you obtain:
a = 3
b = -10
c = 8
Then, you replace these values in the equation (3):

Then, the factorization of the polynomial is:
