Answer:
The answer is the option D
and 
Step-by-step explanation:
we have
we know that
The solution of the system of equations is the intersection point both graphs
Using a graphing tool
see the attached figure
The solution are the points 
and 
therefore
The solution of the equation 
are
so
For 
For 
therefore
and because the intersection points are common points for both graphs
Answer:
what story problem are u talking about
Answer:
14
Step-by-step explanation:
To find the unit rate, we want the denominator to be 1. So 168/12 is 14.
I believe that it's 3/5,because three integers are posotive..out of 5
Given:
b1 = 17 ft
b2 = 20 ft
h = 13 ft
r = 17/2 = 8.5 ft
Area of the Semi-circle = 1/2 π r²
= 1/2 (22/7) (8.5²)
= (11/7) (72.25)
= 113.535 ft²
Area of the trapezium = (h) (b1 + b2) / 2
= (13)(17 + 20)/2
= 240.5 ft²
Total area of the amphitheater stage = Area of Semi-circle + Area of the trazezium = 113.535 + 240.5 = 354.035 ft²
