Converting all to improper fractions
31/10s = 31/5
5×31s=31×10 
155s = 310
s=310/155= 2 
20/9=-4/5m
5×20=-4×9m
100=-36m 
m=100/-36 = 72 28/36 = 72 7/9
-14/5=-7/2n 
-14×2=5×-7n 
-28=-35n 
n =-28/-35
n=28/35
        
             
        
        
        
If the axis is x then you go to y so (6, 5)
 
        
             
        
        
        
Answer: -2
Step-by-step explanation:
 
        
             
        
        
        
The equation for the path of the ball can be measured using a regression model calculator which produced the quadratic model ;
- y(x) = - 16x² + 36x + 4 
- Height at x = 1.7 = 18.89 feets 
<u>The table given</u> : 
Time, x : __0.5 ___ 1 ____ 1.5 ____ 2 
Height, y _ 18 ____22 ___ 24 ____ 12
<u>Using </u><u>technology</u><u> such as a </u><u>quadratic regression</u><u> calculator or </u><u>excel</u> ; 
The quadratic regression model obtained is : 
<u>The </u><u>height after, 1.7 seconds</u><u>, x = 1.7 can be calculated thus</u> : 
Put x = 1.7 in the equation : 
- y(1.7) = - 16(1.7)² + 36(1.7) + 4 
- y = 18.89 feets 
Therefore, the height of the baseball after 1.7 seconds will be 18.89 feets.

Answer:
The quotient is 3x-8
Step-by-step explanation:
(6x^2-x-40)÷ (5 + 2x)
The above equation can be written as
(6x^2-x-40)÷ (2x + 5)
The division is shown in the figure below.
The quotient is 3x-8
