Substitute values for x until they all work.
A. y = 2 x 2 + 5 = 9 fail
B. y = 2 x 2 - 6 = -2 fail
C. y = -2 x 2 - 5 = -9 fail
D. y = -0.5 x 2 - 5 = -6 ok
y = -0.5 x 5 - 5 = -7.5 ok
y = -0.5 x 6 - 5 = -8 ok
Answer:
I think it is dividing the numbers by 2
Find total area
area=pir^2
d/2=r
12=d, 12/2=6=r
area=pi6^2=36pi, pi=3.14
area=113.04 square inches
22 per square inch
113.04 times 22=2486.88
rounded
2487 calories
