Jiao works at least 36 h/wk. she earns $15 /h as a science tutor and $25 /h as a teacher. the number of hours jiao works as a teacher ( y ) is at least twice the number she works as a tutor ( x ). write a set of inequalities represents the constrai nts in this situation?

The set of inequalities that represent this situation is

 and

Step-by-step explanation:

Let

x -----> the number of hours Jiao works as a tutor in a week

y -----> the number of hours Jiao works as a teacher in a week

we know that

-----> inequality A

The solution of the inequality A is the shaded area above the solid line

-----> inequality B

The solution of the inequality B is the shaded area above the solid line  

The solution of the system of inequalities is the shaded area between the positive values of x and y

see the attached figure

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

step-by-step explanation: it is d
