Answer:
the answer would be -13n-23
Step-by-step explanation:
first you want to distribute the brackets 
-7(2+n) = -14-7n
+(-9-6n)
-9-6n
-14-7n-9-6n
combine the n value with an n value and an integer that doesn't have an n value
-7n-6n-14-9
= -13n-23
 
        
             
        
        
        
Answer: 20%.
Step-by-step explanation:
Given, The price of a shirt is marked down from $12.50 to $10.00. 
Previous price = $12.50
New price = $10.00
Change in price = Previous price - New price
= $12.50 - $10.00
= $2.50
Now, the percent decrease of the shirt = 

Hence, the percent decrease of the shirt = 20%.

Answer:
Step-by-step explanation:
y = -3x - 3
m = -3_______
b = -3________  
y = 2x + 2
m = 2_______
b = _2_______
SOLVE NOW   :  -3x - 3  = 2x + 2
- 5x = 5
x = -1
subst in y : y = 2(-1)+2 = 0
the solution is : ( - 1 , 0 )
y = -3x- 3 an equation for the line 'red'    
y = 2x+2 an equation for the line 'bleus'
