You can work no more than 60 hours each week at your two jobs. dog walking pays $7 per hour and your sales job at computers & more, inc. pays $12 per hour. you need to earn at least $450 each week to pay your bills. your friend solves the system of inequalities s250 and tells you that a possible solution is (-3,50). is this a possible solution, why or why not?

The ordered pair (-3,50) is not a possible solution, because the number of hours cannot be a negative number

The solution in the attached figure

Step-by-step explanation:

Let

x-----> the number of hours worked to dog walking job

y ----> the number of hours worked to Computers & More, Inc job

we know that

-----> inequality A

----> inequality B

using a graphing tool

The solution is the triangular shaded area

see the attached figure

The ordered pair (-3,50) is not a possible solution, because the number of hours cannot be a negative number

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
