6. Which of the following numerical expressions results in a negative
number?
A (-7) + (-3)
B (-3) + (7)
C (3) + (7)
D (3) * (-7) + (11)

A

Step-by-step explanation:

The following results in a negative number:   A

In B, C and D the results are positive.

step-by-step explanation:

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
