<h2>Answer:</h2>

The linear inequality that is represented by the graph is:

                y\leq \dfrac{1}{2}x+3

<h2>Step-by-step explanation:</h2>

From the graph of the given function we see that the graph is a solid line passing through (0,3) and (-6,0) and the shading is towards the origin.

Hence, we will check each of the given options.

A)

        y\leq 2x+4

We see that the line of this inequality is a line passing through (0,4) and (-2,0) and shading towards the origin.

Hence, option: A is incorrect.

C)

      y\geq \dfrac{1}{2}x+3

The graph of this inequality is a solid line passing through (0,3) and (-6,0) and the shading is away from the origin.

Hence, option: C is incorrect.

D)

         y\geq 2x+3

The graph of this inequality is a solid line passing through the point (0,3) and (-3/2,0) and shading away from the origin.

Hence, option: D is incorrect.

B)

               y\leq \dfrac{1}{2}x+3

When we plot the graph of this inequality we see that it matches the given graph.

           Hence, option: B is the correct answer.

Oscar charges $25 for the first hour of tutoring and $15 for each additional hour of fraction of an hour counting as a whole hou
makkiz [27]

Answer:

Latoya will charge $10 more to tutor for 5.5 hours

Step-by-step explanation:

We shall look at the total charges of both tutors individually.

Oscar charges $25 for the first hour of tutoring and $15 for each additional hour of fraction of an hour counting as a whole hour.

This means that for the first hour, Oscar charges $25.

For every subsequent hour, regardless of whether the student was tutored for the full hour or only partial, Oscar still charges $15 for the particular hour. To clarify, here is an example.

If a student is tutored for 2 hours, the cost for Oscar's tutoring is $25 (first hour) + $15 (second hour) = $40. However, if the student is still tutored for 1.5 hours, the cost for Oscar's tutoring is still $25 (first hour) + $15 (second hour) = $40. This is because Oscar counts the partial minutes as a full hour in tutoring costs.

For 5.5 hours, the cost of Oscar's tutoring is

$25 (first hour) + $15*4 (2nd to 5th hours) + $15 (the last half an hour) = $100.

Now, we shall look at Latoya's tutoring cost.

f(x) =

30x,

0  \leqslant x \leqslant 3

20x,

3 < x \leqslant 6

10x,

x > 6

The tutoring cost depends on x, the number of tutoring hours. In this case, x is 5.5. The cost for 5.5 hour depends on the formula 20x since 5.5 is more than 3 but less than 6.

Hence, the tutoring cost for Latoya is $20*5.5 = $110.

In this case, Latoya charges $110-$100=$10 more to tutor for 5.5 hours.
