Evelyn has x nickels and y pennies. She has a maximum of 20 coins worth a minimum of $0.40 combined. Solve this system of inequalities graphically and determine one possible solution.

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

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
