Astudent's pay of $18 an hour is $7 more than twice the amount the student earns per hour at an
internship. enter and solve an equation to find the hourly pay of the internship.

5.5d=t

Step-by-step explanation:

d=dollors per hour

t=total money he earns

(18-7)/2=5.5

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

definitely a. the others have almost all data points on one side of the line.
