PLEASE HELP

A.   x < -4  or  x >= 3

Step-by-step explanation:

A solid dot at 3, and shading to the right, means all numbers greater than or equal to 3.

An open dot at -4 and shading to the left means all numbers less than -4.

A number cannot be both 3 or greater AND less than 4, so you must use the word "or" between the the two parts of the answer.

A.   x < -4  or  x >= 3

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

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
