Andy and sam are saving money to go on their senior trip. the amount of money that andy will have at the end of each week, w, can be expressed at a(w) = 20w + 300. the amount of money that sam will have at the end of each week, w, can be expressed at s(w) = 15w + 400. they have decided to combine their savings accounts. write a function that expresses the total amount, t(w) they have in their savings account at the end of each week.

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
