T=number of  tiles bought
cost at store 1 is 0.79t+24
cost at store 2 is 1.19t
when will be equal cost?
0.79t+24=1.19t
minus 0.79t from both sides
24=0.4t
divide both sides by 0.4
60=t
answer is 60 tiles
        
                    
             
        
        
        
Answer:
9 and 11   
Step-by-step explanation:
First number = x -2
Second number = x
   and   2x = 3(x-2)  - 5
             2x = 3x - 6 - 5
              x = 11 
               first number = 11-2 = 9

Answer:
Step-by-step explanation:
Day 1 = 2 birds 
day 2 = 3 birds
day 3 = 9 birds
day 4 = 8 birds
day 5 = 1 bird
On day 1 the points are (1,2)
On day 5 the points are (5,1)
(I am picking these for the points because I don't know your options for the selecting area.)
we use this formula y2-y1/x2-x1
2-5/1-1
3/0
our answer is infinite which is the relation and this is an infinite function
