Answer:

A. yes, the data represents a function because u have no repeating x values. A function cannot have repeating x values...they can have repeating y values, just not the x ones

Step-by-step explanation:

B. table : (8,8)(12,12)(14,16)(16,16)

               look at ur points...when x = 8, y = 8...so the table, when x = 8 has a

               value of 8

relation : f(x) = 8x - 5....when x = 8

             f(8) = 8(8) - 5

             f(8) = 64 - 5

             f(8) = 59....and the relation has a value of 59

Therefore, the relation has a greater value when x = 8 <==

C. f(x) = 8x - 5...when f(x) = 19

    19 = 8x - 5

     19 + 5 = 8x

    24 = 8x

    24/8 = x

    3 = x <==

Gelneren [198K]

Answer:

x= 14

Step-by-step explanation:

First (and only) we subtract 17 from both sides :

17 + x - 17 = 31 - 17

x = 31 - 17

x = 14

Jason owns a small textile company that produces shirts. On a particular day, Jason has one worker come into the shop to make sh
Vesna [10]

Answer:

Variables:

x → The number of hours the worker worked

y → The number of shirts the worker made.

System fo equations:

\left \{ {{25x+1.75 y=270} \atop {y=5x}} \right.

Step-by-step explanation:

Let be x the number of hours the worker worked and y the number of shirts the worker made.

Since:

  • Jason must pay the worker $25 per hour (which can be represented with 25x).
  • He must pay $1.75 per shirt for material costs (which can be represented with 1.75y).
  • The total expenses were $270.

You can write the following equation:

25x+1.75 y=270

Knowing that the worker created an average of 5 shirts per hour, you can write the other equation:

y=5x

Therefore, with this equations you can set up the following system of equations, which could be used to determine the number of hours the worker worked and the number of shirts the worker made:

\left \{ {{25x+1.75 y=270} \atop {y=5x}} \right.
