Answer:

Step-by-step explanation:

Given 900 tickets for sale and restrictions on the numbers of reserved and general admission seats, you want a system of inequalities that models the possible sales. You also want a graph of the feasible region.

The variables are defined as ...

The limits give rise to these inequalities:

  x ≤ 600 . . . . . no more than 600 reserved seats can be sold

  y ≥ 200 . . . . . at least 200 general admission tickets will be sold

  x + y ≤ 900 . . . . at most, 900 tickets can be sold

These inequalities can be graphed simply by giving them as input to a graphing calculator. The result is attached. The feasible region is that area of the graph where the three solution spaces overlap. Here, it is outlined in black.

The value of the composite function (f o g)(3) is 1603

The functions are given as

f(x) = 3x² - 7x - 3

g(x) = -4x - 10

Next, calculate (f o g)(x) using

(f o g)(x) = f(g(x))

So, we have

(f o g)(x) = 3(-4x - 10)² - 7(-4x - 10) - 3

Substitute 3 for x.

So, we have

(f o g)(3) = 3(-4 x 3 - 10)² - 7(-4 x 3 - 10) - 3

Evaluate

(f o g)(3) = 1603

Hence, the value of the composite function (f o g)(3) is 1603

Red and green lines are Parallel lines. and black line is perpendicular to the blue line.

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since the parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.

In the given figure, we have a set of lines which are parallel and perpendicular to each others.

We know that Parallel lines are lies in the same plane which when extended do not meet and are always same distance apart from each other.

The Perpendicular lines are two non-vertical lines in the same plane that intersect at right angles.

From the figure given,

Red and green lines are Parallel lines. and black line is perpendicular to the blue line.

Step-by-step explanation:

The y-intercept of a graph is the point, where the graph crosses the y-axis. and The graph with the given details is graph (c).

According to the statement

We have to find that the correct graph which represent the domain.

So, For this purpose, we know that the

The domain of a function is the set of all possible inputs for the function.

From the given information:

The function that has the domain (–∞, –4) ⋃ (–4, 3) ⋃ (3, ∞), has a y-intercept at (0, 3), and is increasing on the interval (0, 4).

Then

we have given a four graphs as a option which are in the image below after seeing that we know that the:

From the list of given options. graph (d) includes a y intercept of two, because it crossed the y-axis at y = 2.

So, graph (d) can not be the desired graph

And then

Graph (a) features a domain of: (–∞, –5)

So, graph (a) can't be the desired graph

And then

The domain of graph (b) is [-3,3]

So, graph (b) can't be the desired graph.

Hence, the required graph is graph (c).

Where
