Jensen wants to hang a mirror in his boat and put a frame around it. the mirror and frame must have an area of 19.75 square feet. the mirror is 4 feet wide and 5 feet long. which quadratic equation can be used to determine the thickness of the frame, x? (2 points) 2x2 + 6x − 19.25 = 0 3x2 + 5x − 19.25 = 0 4x2 + 18x + 0.25 = 0 4x2 + 18x + 20 = 0

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

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
