Answer:D

Step-by-step explanation:

By solving a linear equation, we will see that the points are vertical only if the value of x is -2.

We say that two points (x₁, y₁) and (x₂, y₂) are vertical if the points have the same x-component and different y-component, so we must have:

x₁ = x₂

y₁ ≠ y₂

In this case, the two points are:

F(3-2x, 12) and G(x+9, 7)

The y-component is different, so we only need to have:

3 - 2x = x + 9

This is a linear equation, below I will solve it:

3 - 2x = x + 9

3 - 9 = x + 2x

-6 = 3x

-6/3 = x

-2  =x

The points are vertical if x = -2.

The value of p that will guarantee the continuity of the function is given as follows:

p = 6.5.

A function defined by f(x) is continuous at a point x = a if it is defined at x = a, and the lateral limits are equal, that is:

[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]

In the context of this problem, the continuity of the function will be guaranteed if the lateral limits at x = -1 are equal.

To the left of x = -1, the function is less than -1, hence the lateral limit is:

lim x -> -1^- f(x) = lim x -> -1 (-2x² - 8x + 3) = -2(-1)² - 8(-1) + 3 = 9.

To the right of -1, the function is greater than -1, hence the lateram limit is:

lim x -> -1^+ f(x) = lim x -> -1 (4x + 2p) = 4(-1) + 2p = -4 + 2p.

The lateral limits have to be equal for the function to be continuous, hence:

-4 + 2p = 9

2p = 13

p = 13/2

p = 6.5.

Step-by-step explanation:

The best estimate of the slope of the best-fit line for the graph at the right will be 7/4.

The ratio of the increase in elevation between two points to the run in elevation between those same two points is referred to as the slope. A line that is moving up will have a positive slope, and a line that is moving down will have a negative slope if you view the line from left to right. A line's slope often indicates the steepness and direction of the line. By calculating the difference between the coordinates of the two points, (x₁,y₁) and (x₂,y₂), it is simple to calculate the slope of a straight line between them. The letter "m" is frequently used to denote slope.

Given Data

x coordinate = 4

y coordinate = 7

Slope = y-coordinate/ x-coordinate

Slope = 7/4

The best estimate of the slope of the best-fit line for the graph at the right will be 7/4.

Using proportions, the explanation for this is that a basketball game has four quarters, hence half-time is at the end of the second quarter.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using the basic arithmetic operations, especially multiplication and division with the unit rates in the problem.

The entirety of a basketball game is composed by:

4 quarters.

Hence the mid-point of the game is calculated as follows:

0.5 x 4 quarters = 2 quarters.

This means that the end of the second quarter is the mid-point of the game, which is why the halftime is positioned at the end of the second quarter.

The input value x in the function k( x ) = 6x - 12 when k( x ) = 15 is 9/2.

A function is simply a relationship that maps one input to one output, that is, each x-value can only have one y-value.

Given the data in the question;

To determine the value of x, equate the function to 15 and solve for x.

k( x ) = 6x - 12

k( x ) = 15

15 = 6x - 12

Rearrange the equation

6x - 12 = 15

Collect like terms

6x = 15 + 12

6x = 27

Divide but sides by 6

6x/6 = 27/6

x = 27/6

x = 9/2

Therefore, the input value (x) is 9/2, this forms an ordered pair of ( 9/2, 15 ).

The dimensions of the deck would be increased by 1 feet.

Area of a rectangle = length x width

Initial area of the deck = 3 x 8 = 24 feet²

Area of the deck when it is increased = (1 + 0.50) x 24  = 36 feet²

Length of the deck after it is increased = 3 + x

Width of the deck after it is increased = 8+ x

Area of the new deck : (3 + x) + (8 + x) = 36

24 + 3x + 8x + x² = 36

x² + 8x + 3x + 24 - 36 = 0

x² + 11x - 12 = 0

The solutions of the quadratic equation are -1 and 12

-1 + x = 0
