X - 8 = 23
x = 23 + 8
x = 31 <== originally on their 31 yard line
        
             
        
        
        
Answer:
C. 2
Step-by-step explanation:
The grid markings are the same distance apart in the x- and y-directions, so a line with slope 1 will make a 45° angle with the x-axis. Your line is steeper than that, so has a slope more than 1.
Your line goes up to the right, so its slope is positive.
The only answer choice that is a positive number more than 1 is ...
... C. 2
_____
The slope is computed as the ratio of rise (vertical change) to run (horizontal change). The two marked points tell you the vertical change is from y=-4 to y=6, a change of 6-(-4) = 10. The horizontal change is from x=1 to x=6, a change of 6-1 = 5.
Then the ratio of rise to run is 10/5 = 2. This matches answer C.
 
        
             
        
        
        
Answer:
-1/2 > x > -3
Step-by-step explanation:
i) 
-2x+3>4
-2x> 1
 x < -1/2
ii)
-2x+3<9
-2x<6
 x > -3
= -1/2 > x > -3
 
        
             
        
        
        
Answer:
89.125%
Step-by-step explanation:
The weighted mean is simply the multiplication of the number of student in each period times the respective average of said period, divided by the total number of students:
Average =  = 89.125%
 = 89.125%
