A graph is a visual representation of data or mathematical concepts. It is a diagram that shows how variables or quantities relate to each other, often using points, lines, bars, or other symbols. In mathematics, a graph can be used to represent a set of points or a function, where the x-axis represents the input values and the y-axis represents the output values. A graph can show the shape of a function, its range, its domain, and other important features.

Here,

To graph the system, we can first graph the boundary lines of the two inequalities.

For the first inequality, y > -x + 3, we can draw the line y = -x + 3 and shade the area above the line. This is because the inequality is y > -x + 3, which means that all points above the line satisfy the inequality.

Next, for the second inequality, -2x + y < -1, we can draw the line -2x + y = -1 and shade the area below the line. This is because the inequality is -2x + y < -1, which means that all points below the line satisfy the inequality.

The correct statement about diagram is m∠1 > m∠4. So correct option is D.

In mathematics, an angle is a measure of the amount of rotation between two rays or line segments that share a common endpoint, known as the vertex. The rays or line segments are typically referred to as the sides of the angle.

Angles are usually measured in degrees or radians, with a full rotation or circle being 360 degrees or 2π radians. Angles can be classified into different types based on their degree of rotation, such as acute angles, which are less than 90 degrees, right angles, which are exactly 90 degrees, obtuse angles, which are greater than 90 degrees but less than 180 degrees, and straight angles, which are exactly 180 degrees.

Angles can be added, subtracted, multiplied, and divided, and they can be used to solve a wide range of problems in geometry and trigonometry. For example, angles are used to calculate the measurements of geometric shapes, such as triangles, circles, and polygons, and they are also used to calculate distances and heights using trigonometric functions such as sine, cosine, and tangent.

Setting x = 0, we get the y-intercept: y = 31/5. So, the equation of the line is y = 6/5x + 31/5.

In geometry, a line intersect is a point where two or more lines cross or meet. When two lines intersect, they share a single point in common, which is called the point of intersection. This point of intersection is the solution to the system of equations formed by the two lines.

by the question.

To find different y-intercepts using the given slopes, we need to use the point-slope form of the equation of a line, which is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line. To find the y-intercept, we can set x = 0 and solve for y.

For slope 1/5, let's choose the point (2, 3) on the line. Using the point-slope form, we get:

y - 3 = 1/5(x - 2)

y - 3 = 1/5x - 2/5

y = 1/5x + 13/5

Setting x = 0, we get the y-intercept: y = 13/5. So, the equation of the line is y = 1/5x + 13/5.

For slope 3/5, let's choose the point (4, 2) on the line. Using the point-slope form, we get:

y - 2 = 3/5(x - 4)

y - 2 = 3/5x - 12/5

y = 3/5x + 8/5

Setting x = 0, we get the y-intercept: y = 8/5. So, the equation of the line is y = 3/5x + 8/5.

For slope 6/5, let's choose the point (-1, 5) on the line. Using the point-slope form, we get:

y - 5 = 6/5(x + 1)

y - 5 = 6/5x + 6/5

y = 6/5x + 31/5

Noah is consistently adding 0.5 gallons of water every minute to a tank. 2 minutes are spent filling a gallon.

The rate of filling is the amount of water that is filled per unit of time. In this instance, Noah is consistently adding 0.5 gallons of water each minute to the tank.

To determine the rate of filling in minutes per gallon, we can simply take the reciprocal of the rate of filling in gallons per minute.

That is:

Rate of filling in minutes per gallon = 1 / Rate of filling in gallons per minute

So, the rate of filling in minutes per gallon is:

1 / 0.5 gallons per minute = 2 minutes per gallon

Therefore, Noah is filling the tank at a rate of 2 minutes per gallon.

Yes, the length and width can be decimal numbers each one with decimal place, but not in every case.

The size of a two-dimensional surface or region is expressed in terms of area. Square units like square inches, square feet, or square metres are frequently used to measure it. The area of a shape or region is determined by counting the number of unit squares that can fit inside it without overlap.  

for example, lets take length =2.5 feet

and width=3.2 feet

area of table top=8 feet²

Taking another case:

length =1.2 feet

and width=3.5 feet

area of table top=4.2 feet²

if the length and width are decimal numbers, then the area would also be a decimal number or whole number, But, this is not possible in every cases.

2.67 oz

In this diagram, the vertical line represents the total amount of water in the cup (8 ounces), and the shaded portion represents the 1/3 cup of water needed for the recipe, which is approximately 2.67 ounces.

Answer:

1/3 cup is approximately equal to 2.67 ounces

Explanation:

In cooking and baking, recipes often use measurements that are different from the standard units of measurement used in daily life. One such measurement is the cup, commonly used to measure liquids like water, milk, and oil. A cup of water typically equals 8 fluid ounces in the United States.

If a recipe calls for 1/3 cup of water, we need to convert this measurement into ounces to know how much water is needed. To do this, we can use the fact that 1 cup is equal to 8 ounces.

To convert 1/3 cup to ounces, we can multiply the number of cups by the number of ounces in one cup. That is:

1/3 cup * 8 ounces/cup = 8/3 ounces

However, 8/3 ounces is not a convenient number to work with, so we need to round it to a more practical value. One reasonable approximation for 8/3 is 2.67. Therefore, we can say that 1/3 cup equals approximately 2.67 ounces.

This approximation is reasonable because it is close to the exact value of 8/3 ounces. Using 2.67 ounces as an estimate for 1/3 cup of water in a recipe should provide a good approximation of the water needed.

The company should use the following values: Price per unit = $1,445; Variable costs per unit = $552; Fixed costs = $4.715 million ; Quantity = 95,000 units.

In algebra, a symbol (typically a letter) is used to represent an undetermined quantitative score in an expression or algebraic expression. Simply put, a variable is a number that may be changed yet remains fixed. Categorical and numeric variables are the two main types of variables. Then, discrete or continuous categories are made for each category for numerical and categorical variables, respectively. An overview of various types is given in this section. a metric that has a wide range of possible values. Something that can change; a variable's sign; an element of a science experiment that could vary.

To perform a best-case and worst-case scenario analysis, we need to adjust the estimates for each variable based on the given percentage error of 15%.

Best-case scenario analysis:

Price per unit = $1,700 + (15% x $1,700) = $1,955

Variable costs per unit = $480 - (15% x $480) = $408

Fixed costs = $4.1 million - (15% x $4.1 million) = $3.485 million

Quantity = 95,000 units (no adjustment needed as it is a fixed quantity)

Worst-case scenario analysis:

Price per unit = $1,700 - (15% x $1,700) = $1,445

Variable costs per unit = $480 + (15% x $480) = $552

Fixed costs = $4.1 million + (15% x $4.1 million) = $4.715 million

Quantity = 95,000 units (no adjustment needed as it is a fixed quantity)

Therefore, for the best-case scenario, the company should use the following values:

Price per unit = $1,955

Variable costs per unit = $408

Fixed costs = $3.485 million

Quantity = 95,000 units

And for the worst-case scenario, the company should use the following values:

Price per unit = $1,445

Variable costs per unit = $552

Fixed costs = $4.715 million

Quantity = 95,000 units

The slope of the line on this graph with points (2, 5) and (4, 4) is equal to: D. =1/2.

In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = rise/run

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Substituting the given data points into the slope formula, we have the following;

Slope (m) = (5 - 4)/(2 - 4)

Slope (m) = -1/2

In this context, we can reasonably infer and logically deduce that the slope of the line on this graph is equal to -0.5 or -1/2.

Answer:

X = 35°

Y = 72.5°

Step-by-step explanation:

x is vertically opposite to 35° so x = 35°

35 × 2 = 70

360 - 70 = 290

290 / 4 = 72.5

Y = 72.5°

Answer:

x = 35

y = 72.5

Step-by-step explanation:

At your level, it is assumed that those lines are straight. Keeping this in mind, we can find the answer to this problem.

First, we have to find x.

x = 35º because opposite angles are equal (xº is opposite to 35º).

Then, we have to calculate y.

You should know that angles in a straight line add up to 180º.

So: yº + yº + 35º = 180º

You know have to solve this equation (solve for y).

y + y + 35 = 180

y + y = 180 - 35

y + y = 145

2y = 145

y = 145 / 2

y = 72.5

Check: 72.5 + 72.5 + 35 = 180

Step-by-step explanation:

The general equation for a sinusoidal function of the form y = a sin b(x + c) + d is:

a is the amplitude (the maximum displacement from the midline).

b determines the period (the distance between two consecutive peaks or troughs).

c is the horizontal shift (the amount by which the graph is shifted horizontally).

d is the vertical shift (the amount by which the graph is shifted vertically).

From the given information, we can see that:

The amplitude is not given.

b = 3, which means the period is 2π/3.

c = 6, which means the graph is shifted 6 units to the left.

d = 9, which means the graph is shifted 9 units up.

Since the amplitude is not given, we need to look at the graph to determine it. However, the graph is not provided, so we cannot determine the amplitude with the given information.
