the parallel line is 2x+5y+15=0.
 
 
Step-by-step explanation:
ok I hope it will work 
soo,
Solution
 given,
 given parallel line 2x+5y=15 
 which goes through the point (-10,1) 
 now,
 let 2x+5y=15 be equation no.1
 
then the line which is parallel to the equation 1st
 2 x+5y+k = 0 let it be equation no.2
now the equation no.2 passes through the point (-10,1)
 or, 2x+5y+k =0
 or, 2*-10+5*1+k= 0
 or, -20+5+k= 0
 or, -15+k= 0
 or, k= 15
putting the value of k in equation no.2 we get,
 or, 2x+5y+k=0
 or, 2x+5y+15=0
which is a required line.
 
 
        
             
        
        
        
Since x dollars is the total monthly sales Paul makes when his sales exceed 20,000 dollars, then the function f(x) should add x dollars and $20,000. The answer is B. x+20,000.
Assuming that x dollars is still the sales after gaining $20,000, then 15 percent of x is modeled by B. 0.15x. 
 
        
             
        
        
        
Answer:
x=4
Step-by-step explanation:
Consider ΔKLJ:
sinθ=opposite/hypotenuse
sin30=LJ/8√2
LJ=0.5*8√2=4√2
Consider ΔMLJ:
sinθ=opp/hyp
sin45=x/4√2
1/√2=x/4√2
4√2/√2=x
x=4
 
        
             
        
        
        
The ratio between the departments is
A: B: C
15000 : 18000 : 9000
15 : 18 : 9
5 : 6 : 3
The budget needs to be divided into 5+6+3 = 14 parts
The budget for one part is 22000/14
The budget for department B is 

Rounded to the nearest dollar, the budget is $9429
