A medical tech uses a pair of four-inch-long tweezers to remove a wood splinter from a patient. The technician is applying 1 lb of squeezing force (Effort Force) to the tweezers. If more than 1/5 lb of force is applied (Force Resistance) to the splinter (“load”), it will break and become difficult to remove. Assuming an ideal effort force, calculate how far from the fulcrum the tweezers must be held to avoid damaging the splinter.

it is b)

hope this : )

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
