In the second step of solving the inequality 5x - 9 < 91, the property used is the addition property of inequalities.

This property states that adding the same value to both sides of an inequality does not change the inequality's direction. By adding 9 to both sides of the inequality, we aim to isolate the variable term. The inequality becomes 5x < 100.

The addition property allows us to perform this operation and maintain the validity of the inequality. It is a fundamental property in solving inequalities, enabling us to simplify and manipulate expressions.

The probability of adding either ground beef or onion as the first ingredient  0.25 or 25%.

If there are a total of 8 ingredients and 2 of them are either ground beef or onion, then the probability would be:

Probability = (Number of desired outcomes) / (Total number of possible outcomes)

           = 2 / 8

           = 1 / 4

           = 0.25

So, the probability of adding either ground beef or onion as the first ingredient is 0.25 or 25%.

In this case, we have a total of 8 ingredients, out of which 2 are either ground beef or onion. When selecting the first ingredient, there are 8 possible outcomes. Since we want to calculate the probability of adding either ground beef or onion as the first ingredient, we count the number of desired outcomes, which is 2 (either ground beef or onion). Dividing the number of desired outcomes by the total number of possible outcomes gives us the probability.

The probability of adding either ground beef or onion as the first ingredient is 0.25 or 25%. This means that there is a 25% chance that either ground beef or onion will be the first ingredient added, assuming the ingredients are added randomly without any specific order.

The point (2, 3, 3), we have:

∂z/∂x = 1/8

∂z/∂y = -1/6

To use the equations given in the problem, we first need to check if Fz is not equal to zero at the point (2, 3, 3) in the equation 3z^3 − 3xy − 5yz + y^3 −9 = 0.

We can find Fz by taking the partial derivative of F with respect to z:

Fz = 9z^2 - 5y

At (2, 3, 3), we have:

Fz(2, 3, 3) = 9(3)^2 - 5(3) = 72

Since Fz is not equal to zero at the point (2, 3, 3), we can use the equations given in the problem to find ∂z/∂x and ∂z/∂y.

∂z/∂x = −Fx/Fz

To find Fx, we take the partial derivative of F with respect to x:

Fx = -3y

Therefore,

∂z/∂x = −Fx/Fz = -(-3y)/72 = 3y/72 = y/24

At the point (2, 3, 3), we have:

∂z/∂x (2, 3, 3) = 3/24 = 1/8

∂z/∂y = −Fy/Fz

To find Fy, we take the partial derivative of F with respect to y:

Fy = -5z + 3y^2

Therefore,

∂z/∂y = −Fy/Fz = -(-5z + 3y^2)/72 = (5z - 3y^2)/72

At the point (2, 3, 3), we have:

∂z/∂y (2, 3, 3) = (5(3) - 3(3)^2)/72 = -4/24 = -1/6

Therefore, at the point (2, 3, 3), we have:

∂z/∂x = 1/8

The new coordinates of the point in the transformed shape would be (-1/2x, -1/2y).

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

A scale factor of -1/2 around the center point (0,0) would reflect the shape across the origin and also shrink it by a factor of 1/2.

The transformation can be represented by the matrix:

[-1/2 0]

[ 0 -1/2]

This matrix would be applied to the coordinates of each point in the shape to obtain the new coordinates of the transformed shape.

So, if a point in the shape had coordinates (x, y), the new coordinates of the point in the transformed shape would be (-1/2x, -1/2y).

3r + 12 ≤ 30

Step-by-step explanation:

He can spend at most $30, so the amount he can spend is less than or equal to (≤) $30.

amount he will spend ≤ 30

Let r = number of rides.

The amount he will spend is composed of 2 parts:

(a) a fixed cost of $12.00, or just 12.

(b) a per ride cost of $3.00, or 3r.

amount he will spend = 3r + 12

Since we know the amount must be less than or equal to $30.00, the inequality is:

3r + 12 ≤ 30

Answer:

The total price he will pay is 89.89.

Step-by-step explanation:

112.99 - 112.99*0.2 = 90.392 (this is the 20 percent off for online purchases)

90.392 - 90.392*0.1 = 81.3528 (this is the 10 percent off coupon)

81.3528 + 81.3528*0.065 = 86.640732 (this is the 6.5% sales tax)

86.640732 + 3.25 = 89.890732 (this is the shipping cost)

To calculate the margin of error, you need to determine the critical value associated with the desired level of confidence. The margin of error is then obtained by multiplying the critical value by the standard deviation.

Let's assume you want to calculate the margin of error for a 95% confidence level. For a normal distribution, the critical value corresponding to a 95% confidence level is approximately 1.96.

Margin of Error = Critical Value * Standard Deviation

Using the given values:

Standard Deviation = 0.08

For a 95% confidence level:

Critical Value = 1.96

Margin of Error = 1.96 * 0.08

Calculating the margin of error:

Margin of Error = 0.1568

Therefore, the margin of error is approximately 0.1568

The domain of the square root function is:

x ≥6

Remember that for any function y = f(x), we define the domain as the set of the possible inputs of the function. That is, the set of the possible values of x.

Here we have the square root function:

f(x) = √(x - 6)

Now, remember that the argument of a square root must be zero or larger, then to find the domain we need to solve:

x - 6 = 0

x = 6

Then the domain is the set of all the values equal to or larger than 6.

Solution :

the differences in the X coordinates and Y coordinates:

The x-coordinate tells you how many steps you have to take to the right (positive) or left (negative) on the x-axis. And the y-coordinate tells you have many steps to move up (positive) or down (negative) on the y-axis.

Given : difference in the x-coordinates of two points is 3

the difference in the y-coordinates of the two points is 6

The slope of the line :

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in the y-coordinate is represented by Δy and the net change in the x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

Tan θ = Δy/Δx can also represent the slope of the line

So, tan θ to be the slope of a line.

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The letter ‘ m’ usually represents the slope.

If P(x1,y1) and Q(x2,y2) are the two points on a straight line, then the slope formula is given by:

Slope,

m = Change in y-coordinates/Change in x-coordinates

m = (y2 – y1)/(x2 – x1)

Therefore, based on the above formula, we can easily calculate the slope of a line between two points.

In other terms, the slope of a line between two points is also said to be the rise of the line from one point to another (along the y-axis) over the run (along the x-axis). Therefore,

Slope, m = Rise/Run

Use the slope formula.

the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or

the change in the y values over the change in the x values.

The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2. It does not matter which point you label as the first point and which you label as the second. Don't forget to include the correct sign of each value. Simplify to get the value of the slope. Check the your answer by graphing the points and verifying that the vertical distance between the two points and the horizontal distance between the two points is captured by the numerator and denominator of the slope

There's a small trick here. You have to double the thickness. Why? Because the outside diameter goes through the thickness twice.

Inside diameter = outside diameter - 2 * thickness

outside diameter = 1 1/4 inches

thickness = 5/16

Inside diameter = 1 1/4 - 2 * 5/16

inside diameter = 5/4 - 10/16

Inside diameter = 5/4 - 5/8

Inside diameter = 10/8 - 5/8

Inside diameter = 5/8

What is Graph ?

In mathematics, a graph is a visual representation of a set of objects, such as numbers or data points, and the relationships between them. Graphs can be used to represent a variety of mathematical concepts, including functions, sets of data, and geometric shapes.

The function f(x) = -|x| - 12 is a piecewise function. When x is greater than or equal to zero, the function simplifies to f(x) = -x - 12, and when x is less than zero, it simplifies to f(x) = x - 12.

If we graph both of these pieces separately, we get two straight lines that intersect at the point (0, -12), where the absolute value of x changes sign. The slope of both lines is -1, which means they are both downward sloping with a negative slope.

When we graph this function in the standard viewing window of -10 to 10, we can see the part of the graph where x is greater than or equal to zero, which is the left side of the graph, but the part where x is less than zero, which is the right side of the graph, is outside the viewing window.

Therefore, we can only see a portion of the graph of this function in the standard viewing window of -10 to 10.
