Answer:
no solution
Step-by-step explanation:
y = -2x + 3
6x + 3y = -3
the substitution method means you plug one equation into the next, because the first equation gives us a solution for y we can go ahead and plug that into y of the second equation
6x + 3(-2x + 3) = -3
6x - 6x + 9 = -3
9 = -3
which is false meaning that there are no solutions and the lines don't touch at any point
 
        
             
        
        
        
So supplementary is an 180 angle and complimentary is 90 degree angle so that being said I could be wrong but that looks like a complimentary so a 90 degree angle it’s a 90 degree
        
             
        
        
        
Answer:
10692 cubic inches
Step-by-step explanation:
Since we are told to give the units in inches, let's convert the two values which are in feet.
1 ft= 12 inches
thus,
length 2.75 ft. = 33inch
breadth 4.5 ft. = 54 inch
and height is 6 inches.
Volume of a cube= length × width × height
                             = 33 × 54 × 6
                              = 10692 cubic inches 
 
        
             
        
        
        
Answer:
12.5v+25=130
v=8.4
You can’t visit 8.4 times. So you would need to visit 9 times to get a sufficient amount for a ticket.
