Solving the inequality  [tex]\frac{2x + 4}{2}[/tex] < 6, we get x < 4.

Linear Inequalities are mathematical expressions which consist of a left hand side and a right hand side connected with inequality signs like <, >, ≤, ≥ and ≠.

They are almost like linear equations when we see it, but the '=' sign in linear equations are substituted with inequality signs like those mentioned earlier.

The expression given here is,

[tex]\frac{2x + 4}{2}[/tex] < 6

Multiplying both sides with 2, we get,

2x + 4 < 6 × 2

2x + 4 < 12

Subtracting both sides with 4, we get,

2x + 4 - 4 < 12 - 4

2x < 8

Dividing both sides by 2,

2x / 2 < 8 / 2

x < 4

Hence the inequality [tex]\frac{2x + 4}{2}[/tex] < 6 results in x < 4.

The time t at which the population is 500 is 45 hours.

The equation gives the rate of change of the population at time t:

dP/dt = kP

where P is the population at time t and k is the constant of proportionality.

We can use this equation to find the value of k by substituting the known values of P and t at time t=24 hours:

dP/dt = kP

1000 = k*300

k = 1000/300

k = 10/3

Now that we know the value of k, we can use the equation to find the time t at which the population is 500:

dP/dt = kP

500 = (10/3)P

P = 500*3/10

P = 150

Since the population at time t=0 hours is 300, the population has decreased by 150 over the 24 hours, so t = -150/(-10/3) = 45 hours.

Therefore, the time t at which the population is 500 is 45 hours.

dP/dt = kP

We can use this equation to find the value of k by substituting the known values of P and t at time t=24 hours:

dP/dt = kP

1000 = k*300

k = 1000/300

k = 10/3

dP/dt = kP

500 = (10/3)P

P = 500*3/10

P = 150

Since the population at time t=0 hours is 300, the population has decreased by 150 over the 24 hours, so t = -150/(-10/3) = 45 hours.

Therefore, the time t at which the population is 500 is 45 hours.

The slope-intercept form of a straight line of equation 5x + 2y = 10 is y = (-5/2)x + 5.

The slope-intercept form of a line is:

y = mx + b

where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).

To put the equation 5x + 2y = 10 in slope-intercept form, we need to solve for y. We can do this by rearranging the terms and isolating y:

2y = -5x + 10

y = (-5/2)x + (10/2)

Thus, the slope-intercept form of the equation 5x + 2y = 10 is:

y = (-5/2)x + 5

This means that the slope of the line is (-5/2) and the y-intercept is (0,5).

A unique array value is a value that appears only once among all the other values in the given array. Hence the name unique.

An array is a set of items, images, or numbers arranged in rows and columns. Arrays are practical illustrations of multiplication ideas.

Arrays are needed in cases where you need  to store and manipulate large amounts of data efficiently.

Some of the benefits of using arrays include:

1. Arrays allow you to store a large number of items in a single data structure, which makes it easier to work with large datasets.

2. Arrays allow you to access and modify the items in the array quickly, using the index of the item.

A data structure called an array is used to hold a number of elements together. Each item in an array is recognized by its index, or place within the array. A value that only appears once in an array is considered to be unique array value. Think about the following array, for instance:

[1, 2, 3, 4, 5, 6]

Because each value only occurs once in this array, each value is distinct.

Contrarily, think about the following array:

[1, 2, 3, 3, 4, 5]

Since it appears twice in this array, the number 3 is not unique. Since they only exist once, each of the other values is distinct.

Answer:

Step-by-step explanation:

The y-intercept of g(x) is 3 * 2 = 6.

To find the x-intercepts of g(x), we need to find the values of x that make g(x) equal to 0. Since g(x) = 2f(2x + 3), this means we need to find the values of x that make f(2x + 3) equal to 0. Therefore, we can find the x-intercepts of g(x) by solving the equation f(2x + 3) = 0 for x.

Since the x-intercepts of f(x) are at 2 and -4, this means that the equation f(x) = 0 has solutions at x = 2 and x = -4. Substituting these values into the equation f(2x + 3) = 0, we get:

f(2(2) + 3) = 0

f(4 + 3) = 0

f(7) = 0

and

f(2(-4) + 3) = 0

f(-8 + 3) = 0

f(-5) = 0

Therefore, the x-intercepts of g(x) are at x = 7/2 and x = -5/2. These are the only intercepts of g(x) that we can determine for certain.

Inspect the graph to see if any vertical line drawn would intersect the curve more than once.

What is graph?

A graph is a structure that resembles a set of items in discrete mathematics, more especially in graph theory, in which certain pairs of the objects are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

If there is any such line, the graph does not represent a function. If no vertical line can intersect the curve more than once, the graph does represent a function.

The absolute value of a number is the non-negative distance between the number and zero on a number line, regardless of sign.

This means that the absolute value of a negative number is always positive. Therefore, if a and b both are negative numbers, their absolute values will be positive numbers. If a is greater than b, then the absolute value of a must be greater than the absolute value of b. This can be expressed mathematically as follows:

|a| > |b|

This equation states that the absolute value of a is greater than the absolute value of b. In other words, the distance between a and zero is greater than the distance between b and zero on a number line.

To illustrate this, let’s take an example of two negative numbers, a=-3 and b=-5. The absolute values of these two numbers are 3 and 5 respectively. Since 3 is greater than 5, the absolute value of a is greater than the absolute value of b. This holds true regardless of the sign of the numbers, as long as a is greater than b.

The end behavior of the graph of f(x) = x^5 + 8x^4 + 16x^3 is asymptotic: it goes towards positive infinity as x approaches positive infinity, and negative infinity as x approaches negative infinity.

The end behavior of the graph of a polynomial function with degree 5 is determined by the leading term, which in this case is x^5. Since the degree of the leading term is odd and the coefficient is positive, the graph of f(x) = x^5 + 8x^4 + 16x^3 will approach positive infinity as x approaches positive infinity, and negative infinity as x approaches negative infinity. This is known as an asymptotic end behavior. As the x-values get larger and larger, the magnitude of the y-values will also get larger and larger, approaching infinity in either direction. This can be seen by looking at the graph of the function, which will have an "S" shape that curves up and to the right (positive infinity) for large positive x-values, and down and to the left (negative infinity) for large negative x-values.

For x > 0, the end behavior is:

f(x) = x5 + 8x4 + 16x3

lim x→∞ f(x) = lim x→∞ x5 + 8x4 + 16x3

lim x→∞ f(x) = lim x→∞ x5

lim x→∞ f(x) = +∞

For x < 0, the end behavior is:

f(x) = x5 + 8x4 + 16x3

lim x→−∞ f(x) = lim x→−∞ x5 + 8x4 + 16x3

The price of the two pencils is Rs.100 (expensive) and Rs.60 (cheaper).

Let the price of the expensive pencil be = x

And the price of the cheaper one be = y.

According to the question:

The difference between the price of 2 = 40

Therefore,

x- y =40

Total amount = 1800.

The number of Expensive pencils that can be bought = 1800/x.

The number of Expensive pencils that can be bought = 1800/y.

According to the question,

1800/y -1800/x = 15 (the number of extra pencils)

= (1800x -1800y)/xy = 15

= 1800x -1800y =15xy

= 1800 (x-y) =15xy

Substituting x-y as 40

1800 x 40 =15xy

xy = 4800.

We know that x-y =40

Therefore, x = y+ 40

xy = 4800

(y+40) y = 4800

[tex]y^{2}[/tex] + 40 y = 4800

Using the quadratic equation formula,

y = 52.111 or y = -92.111

Thus, the cost of the cheaper pencil (y)= Rs. 52.111

The cost of the expensive pencil (x) = 52.111 + 40 = Rs 92.111

Therefore the cost of two pencils is =   Rs. 52.111 and Rs 92.111.
