What is -4x - 10 ≤ 2?

x≥-3

Step-by-step explanation:

-4x-10≤2

-4x≤2+10

-4x≤12

x≥12÷-4 (The sign flips around when you divide by a negative number.)

x≥-3

i believe the answer is letter c) 8

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
