Let x be the number. Then, we have the inequality:

3(x + 15) ≤ 19

Expanding the left side:

3x + 45 ≤ 19

Subtracting 45 from both sides:

3x ≤ -26

Dividing both sides by 3:

x ≤ -8.67

So, the solution to the inequality is x ≤ -8.67, which means that the number x must be less than or equal to -8.67.

Answer:

\(f(x) = -5(x+1)^2\)

Step-by-step explanation:

We are given the following function:

\(f(x) = x^2\)

Shift 1 unit right.

Shifting a function a units to the right is finding f(x+a). So

To shift one unit right:

\((x+1)^2\)

Vertically stretch by a factor of 5.

To vertically stretch by a factor of 5, we multiply the function by 5. So

\(5(x+1)^2\)

Reflect over the x-axis.

To reflect over the x-axis we multiply the function by -1. So

\(f(x) = -5(x+1)^2\)

The value of width will be;

⇒ 18.5 cm

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The volume of a rectangular prism = 6,618.375 cm³

The height is 13.25 cm and the length is 27 cm.

Now,

We know that,

The volume of rectangular prism = Length x Width x Height

Substitute all the values, we get;

⇒ 6,618.375 = 27 × x × 13.25

⇒ 6,618.375 / 357.75 = x

⇒ x = 18.5 cm

Thus, The value of width = 18.5 cm

Answer:

Step-by-step explanation:

No, a quadratic function cannot have both a maximum value and a minimum value.

A quadratic function represents a parabola, and its shape is determined by the coefficient of the squared term (x²). If the coefficient is positive, the parabola opens upward, and if it is negative, the parabola opens downward. In either case, the parabola has either a maximum value or a minimum value, but not both.

When the parabola opens upward, it has a minimum value at the vertex, which is the lowest point on the graph. Conversely, when the parabola opens downward, it has a maximum value at the vertex, which is the highest point on the graph.

Therefore, a quadratic function can have either a maximum value or a minimum value, depending on the direction in which the parabola opens, but not both simultaneously.

Step-by-step explanation:

To solve for x in the equation 4x3 = -5x - 21, we can follow these steps:

1. Move all the terms containing x to one side of the equation, and move the constant term to the other side. We can do this by adding 5x to both sides and then adding 21 to both sides:

   4x3 + 5x = -21

2. Factor out x from the left-hand side of the equation:

   x(4x2 + 5) = -21

3. Divide both sides by (4x2 + 5):

   x = -21 / (4x2 + 5)

So the solution for x is x = -21 / (4x2 + 5). Note that this is a rational function, which means that the value of x depends on the value of the variable x. This equation has no real solutions because the denominator is always positive, and the numerator is negative.

Answer:

3rd option: 32/24

Step-by-step explanation:

8/6 = 4/3

1st option: Now let's change the denominator to 24:

4/3 ==> ?/24

4/3 =

4*8 / 3*8 = 32/24, not 3/24.

2nd option: Now let's change the numerator to 24:

4/3 ==> 24/?

4/3 =

4*6 / 3*6 = 24/18, not 24/32

24/32 = 3/4, not 4/3 ==> don't get confused by this

3rd option: 32/24 is correct [Look at the explanation for 1st option]

4/3 ==> ?/24

4/3 =

4*8 / 3*8 = 32/24, not 3/24.

Hence, the 3rd option is correct.

Answer:

\(y-2=3(x-4)\)

Step-by-step explanation:

We are given a line contains the point (4, 2).

We also know that the line is parallel to y= 3x - 7.

We want to write the equation of this line.

Parallel lines have the same slopes.

First, let's find the slope of y = 3x - 7.

3 is in the place of where m (the slope) is, so that means it is the slope of that line.

It is also the slope of the line whose equation we want to write.

The equation of the line can be written in three ways:

All of these ways are valid, but for this problem, let's write the equation in point-slope form, as it is the easiest.

Substitute 3 as m in \(y-y_1=m(x-x_1)\).

\(y-y_1=3(x-x_1)\)

Now, substitute 4 as \(x_1\) and 2 as \(y_1\).

\(y-2=3(x-4)\)

So we're trying to find 15% of $25.90... we can say that the $25.90 is 100% of Madison's Manicure... 100% can also be written as 1.0... why? well if 1.0 is 100%, then we can say any other percentage is proportionate to this... for example... 0.25 is 25% of 1.0... In this case... we are trying to add an additional 15% to the 100% price of the manicure... (Remember... with our proportion we can say that 115% is the same as 1.15) If we take our proportion:

1.15 x 25.90 = 3.89

4.00 is the closest to 3.89

The incenter of a triangle is the center of the circle that is inscribed inside the triangle and touches all three sides of the triangle. It is the point in the triangle that is equidistant from all three sides. The incenter is useful in situations where it is important to be equidistant from the sides of a triangle, such as in the example of a store wanting to be in the center of a city that is shaped like a triangle.

Step-by-step explanation:

The centroid of a triangle is the point where the three medians of the triangle intersect. The medians of a triangle are lines that connect each vertex of the triangle to the midpoint of the opposite side. The centroid is also known as the center of mass or balance point of the triangle. It is useful in situations where it is important to find the center of balance of a triangle, such as in the example of building a triangular desk and wanting to place the legs in the center of the triangle.

If Jayla makes her goal 80% of the time, we can say that she has a probability of 0.8 of achieving her goal on any given day.

The probability of Jayla making her goal every day for the next 10 days can be calculated by multiplying the probability of her achieving her goal on each day.

Assuming each day's result is independent of the previous day, the probability of Jayla making her goal every day for the next 10 days is:

0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 = 0.1073741824

So, there is approximately a 10.7% chance that Jayla will make her goal every day for the next 10 days.

Answer:

To answer the question, let's calculate the median and mean of the given salaries.

The median is the middle value when the data is arranged in ascending order. In this case, the middle value is 737 since there are an odd number of values.

The mean is calculated by summing all the values and dividing by the number of values. Let's calculate it:

Sum of salaries = 547 + 596 + 647 + 655 + 737 + 745 + 750 + 780 + 834 = 6591

Number of salaries = 9

Mean = Sum of salaries / Number of salaries = 6591 / 9 = 732.33 (rounded to two decimal places)

Now, let's see what happens when the $834 salary changes to $1005.

(a) What happens to the median?

The median remains the same. Changing one value in the data set does not affect the position of the middle value.

(b) What happens to the mean?

To calculate the new mean, we need to subtract the old value ($834) and add the new value ($1005) to the sum of salaries:

New sum of salaries = 6591 - 834 + 1005 = 6756

New mean = New sum of salaries / Number of salaries = 6756 / 9 = 750.67 (rounded to two decimal places)

Therefore, the mean increases by $18.34.

So, the answer to (a) is "It stays the same" and the answer to (b) is "It increases by $18.34".

The graph does not represent a function between y and x.

A function is a relation that maps inputs x into outputs y, such that each input is mapped into at most one output.

To check if a graph belongs to a function, we need to do the vertical line test, this means that if we draw a vertical line on the coordinate axis where we have the graph, and that vertical line touches the graph at more than one point, then the graph does not represent a  function.

In this case, if we draw a line at x = 1 we will intersect the graph twice, then it is not a function.

In the proportion (5x + 1):3 = (2x + 2):7, the value of x is -1/29.

In the proportion (6x):(4x) = 7, there is no value of x that satisfies the proportion.

To find the value of x in the given proportions, let's solve them one by one:

(5x + 1) : 3 = (2x + 2) : 7

To solve this proportion, we can cross-multiply:

7(5x + 1) = 3(2x + 2)

35x + 7 = 6x + 6

Subtracting 6x from both sides and subtracting 7 from both sides:

35x - 6x = 6 - 7

29x = -1

Dividing both sides by 29:

x = -1/29

Therefore, the value of x in the first proportion is -1/29.

(6x) : (4x) = 7

To solve this proportion, we can simplify the left side:

6x / 4x = 7

Dividing both sides by 2x:

3/2 = 7

This equation is not true, as 3/2 is not equal to 7.

Therefore, there is no value of x that satisfies the second proportion.

In summary, the value of x in the proportion (5x + 1) : 3 = (2x + 2) : 7 is -1/29, and there is no value of x that satisfies the proportion (6x) : (4x) = 7.
