A, C and E all work in the equations. In order for them to work, you must use the ordered pair in each of the three situations. Below is the work for all of the correct answers. 
Ordered Pair A : (1, -1)
y < x + 1
-1 < 1 + 1
-1 < 1 (TRUE)
y < 4
-1 < 4 (TRUE)
x < 6 
1 < 6 (TRUE)
Ordered Pair C : (4, 2)
y < x + 1
2 < 4 + 1
2 < 5 (TRUE)
y < 4
2 < 4 (TRUE)
x < 6 
5 < 6 (TRUE)
Ordered Pair E : (4, -2)
y < x + 1
-2 < 4 + 1
-2 < 5 (TRUE)
y < 4
-2 < 4 (TRUE)
x < 6 
4 < 6 (TRUE)
        
             
        
        
        
Answer:
4
Step-by-step explanation:
Volume= length*width*height
72=Length*3*6
72=Length*18
divide by 18 both sides to get Length=4 inches
 
        
             
        
        
        
Answer:
800 miles
Step-by-step explanation:
Set up an equation, where x is the number of miles driven:
0.10x + 120 = 200
Then, solve for x:
0.10x = 80
x = 800
So, the maximum number of miles he can drive is 800 miles
 
        
             
        
        
        
Answer:
X=-14.5 Y=3.2
Step-by-step explanation:
5x-13=5y+7x
subtract 7x from both sides
-2x-13=5y
subtract 5y from both sides
-2x-5y-13=0
add 13 to both sides
-2x-5y=13
<u>SYSTEMS OF EQUATIONS NOW</u>
4x+15y=-10
-2x-5y=13
multiply the second equation by 3
4x+15y=-10
-6x-15y=39
add the equations together to get:
-2x=29
divide both by -2
x=-14.5
Substitute x into one equation
4(-14.5)+15y=-10
-58+15y=-10
add 58 to both sides
15y=48
divide both sides by 15
y=3.2
<em>CHECK YOUR WORK</em>
4(-14.5)+15(3.2)=-10
-58+48=-10
-10=-10
