What is the graph of f SOMEONE help me please
Svetradugi [14.3K]

Answer:

f(x) = 1/2x + 6

Step-by-step explanation:

So before we even look at the first given formula, let's use the second formula: f(x) = -5.

Plug this formula into the x:

0 <= -5 <= 7

Is this true? Is -5 greater than or equal to 0 and less than or equal to 7?

No, this is false.

So the formula, f(x) = -5, is not the graph of f.

That only leaves one possible option!

In a specific video game scenario, you are given 1,000 gold. You can either train marines to defend your base at 50 gold a piece
Sloan [31]

Answer:

The system is:

                50m+200u\leq 1,000

                 u\leq 3

                 u\geq 0

                 m\geq 10

Step-by-step explanation:

The variables of your equations are:

       m=\text{number of marines}

       u=\text{number of upgrades}

The constraints, which become inequalities are:

<em><u>1. The total cost cannot be greater than 1,000 gold</u></em>

  • Cost of training m number of marines at 50 gold a piece:

               50m

  • Cost of purchasing u number of research weapon upgrades at 200 gold per upgrade:

                200u

  • Total cost:

                50m+200u

  • The cost is limited to 1,000 gold that you are given:

                50m+200u\leq 1,000

          That is the first inequality of your system

<em><u>2. The game allows a maximum of three upgrades:</u></em>

  • This sets an upper bound for the variable:

                   u\leq 3

  • Add the reasonable constraint that the number of upgrades cannot no be negative:

                   u\geq 0

<em><u>3. You know that you need at least ten marines trained to survive </u></em>

  • This sets a lower bound for the variable:

                  m\geq 10

And those are all the four inequalities that form your <em>system to describe the number of marines and the number of upgrades you can train/purchae in the game:</em>

                50m+200u\leq 1,000

                 u\leq 3

                 u\geq 0

                 m\geq 10
