You work as a cashier for a bookstore and earn $4 per hour. you also baby sit and earn $8 per hour. you want to earn at least $56 per week, but would like to work no more than 16 hours per week. given the graph of the linear system, which system is the solution of the real world problem

let x be the number of hours worked as a cashier

and y be the number of hours worked as a babysitter

4x+8y=> 56 (1)

x+y= < 16          (2)

graph each inequality

(1)  line going trough those points  (x=0, y=7); (x=14 , y=0)

above the line and on the line are good solutions

(2) line going trough those points (x=0, y=16); (x=16, y=0)

under the line and on the line are good solutions

the intersection of the graphs is the solution 

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
