Answer:
the slope of line j is -1/8, the slope of lines m and n are both 8.
Explanation step by step:
Suppose j is the slope of line j, m the slope of line m and n the slope of line n. Since:
1. line j is perpendicular of line m, so j*m= -1
2. J is perpendicular of line n, so j*n=-1
3. m and n and parallel so m=n
As we want to know the slope of j we clear the equations presented to us in order to find it.
(1) m* n* j = -8, since n=m we have 
* j = -8.
we clear j; 
replacing in the equation n*j = -1 we get
n*(-8/n^2) = -1. Thus n = 8. Since j = -1/n = -1/8.
in a year she earns=19200
So in a month she earns=19200/12
=1600
So she earns 1600 every month.
If the answer is correct then make me brain list.please
Let, number of solid color gift sold is x and printed gift wrap is y.
Also, number of printed paper sold , 325.
Expressing, it in mathematical equation :
y = 325 ....... 1)
Also, The band needs to earn $2,500 for an upcoming competition.
So ,
3.5x + 5y = 2500 ....... 2)
Solving equation 1 and 2 :
3.5x + 5(325) = 2500
3.5x = 2500 - 1625
3.5x = 875
x = 250
Therefore, number of solid paper they must sell is 250.
Hence, this is the required solution.

Answer: xy
Step-by-step explanation:
Combine like terms to get 9xy-8xy
Then subtract the coefficient to get 1xy
Your finally answer is xy because you don’t need to include the coefficient of 1
