Distance = rate x time
distance = 60 miles per hour x 7 1/2 hours
distance = 450 miles
        
                    
             
        
        
        
Answer:
26in^2
Step-by-step explanation:
5 time 4 is 20in^2. plus 2 times 3 is 6in^2.
add 20 and 6 then you get 26in^2.

Answer:
No solutions
Step-by-step explanation:
If we try to solve this system for y at x = 1, we get an impossible situation:

Clearly, 1 ≠ -15, and we'll see that any value of x that we pick gives us two contradictory values for y, so this system has no solutions.
 
        
             
        
        
        
Answer:
-54
Step-by-step explanation:
Find f( - 3) × g(4),
 for f(x) = x^ - 3
f(-3) = -3^ - 3= -3 × -3 × -3= -27
 and g(x) = x^½ 
g(4) = 4^½ = 2^2^½ = 2 ^1 = 2
 f( - 3) × g(4) = -27 ×2 = -54
