How do I name this circle?

I believe it can be named by the corresponding variables.

Step-by-step explanation:

Every thing that the letters are connecting to are corresponding meaning their together so it might be im not sure on this one but it might be F-B

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
