Consider U = {x|x is a real number}
A= xx E U and x + 2 > 10)
B = {xx E U and 2x > 10}
Which pair of statements is true?
5 € A: 5 EB
6 EA 6 EB
8 € A 8 EB
9 EA: 9 EB

a is the correct

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
