On solving the provided question, we got to know that -  to plot the graph, required equation is 3x +y -8 = 0

a collection of numbers, symbols, and operators (like + and ) that represent a value. Examples -  2 + 3 is a formula and there is also the statement 3 x/2. The equals symbol does not appear in expressions. Actually, none of these = ≠ < > ≤ ≥

We frequently have to understand a written phrase in order to write an expression. For instance, the notation x + 6 can be used to represent the phrase "6 added to some number," where x stands for the unknown value.

To plot the graph,

we need to find the equation first.

and to find the equation -

[tex](y - y1) = m(x - x1)\\here,\\x1 = 1\\y1 = 5\\m- ( -3 )[/tex]

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

-3x + 3 = y-5

3x - 3 = 5-y

There are 28 males and 11 females in the class.

What is a linear equation?

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.

Let the number of males be x and the number of females be y. We know that x = y + 17 and x + y = 39.

Substituting the first equation into the second equation, we get:

y + y + 17 = 39

2y + 17 = 39

2y = 22

y = 11

The number of females is 11, and the number of males is x = y + 17 = 11 + 17 = 28.

Hence, there are 28 males and 11 females in the class.

The correct answer is (a) 10-15, 15-20. This is an example of a Discontinuous class.

In the context of statistical data and classification, a class is a group of observations or data points that share certain characteristics. Classes can be either continuous or discontinuous, depending on whether the values or categories they represent are continuous or not.

A discontinuous class is a set of values or categories that are not continuous, meaning there are gaps or breaks between them. In this case, the classes 10-15 and 15-20 are discontinuous because there is a gap between them at 15. In contrast, the classes 5-9 and 10-14 are continuous because there are no gaps between them, and 0-5 and 10-15 are also continuous because the lower bound of the second class is equal to the upper bound of the first class.

The linear equation for the given chart is: y = -3x + 7.

From the chart given, we can use two pairs of values to find the slope (m) and the y-intercept (b), then plug in their values into the equation that is expressed in slope-intercept form as y = mx + b.

Using two points, (1, 4) and (3, -2), find the slope (m):

Slope (m) = change in y / change in x = (-2 - 4) / (3 - 1)

Slope (m) = -6/2

Slope (m) = -3

Find the y-intercept (b) by substituting m = -3 and (x, y) = (1, 4) into y = mx + b:

4 = -3(1) + b

4 = -3 + b

A number with vertical lines on either side means the absolute value of that expression, i.e. how far it is from 0. An absolute value can be 0 or positive but never negative.

|-18| = 18

|-22| = 22

|30| = 30

Positive numbers are bigger, greater, or higher than zero. They are on the opposite side of zero from the negative numbers. Negative numbers get smaller the farther they are from zero.

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

Let the 2 games be Game 1 and Game 2

Now , the equation will be

The number of points in Game 1 = 12

The number of shots in Game 1 = 14

And ,

The number of points in Game 2 = 18

The number of shots in Game 2 = w

So , the proportion equation is given as

Number of points in Game / number of shots in Game = number of points in Game / number of shots in Game 2

Substituting the values in the equation , we get

12 / 14 = 18 / w

Multiply by 14 on both sides of the equation we get

12 = ( 18 x 14 ) / w

Multiply by w on both sides of the equation , we get

12w = 18 x 14

Divide by 12 on both sides of the equation , we get

w = ( 18 x 14 ) / 12

On simplifying the equation , we get

w = 3 x 7

w = 21

Therefore , the value of w is 21

Hence , The proportion is 12 : 14 : : 18 : w and the value of w is 21

Yes, because angles 1 and 2 are supplementary.

Parallel lines are two lines that do not intersect, or technically, intersect only at infinity.

In this problem, we have that angles 1 and 2 are supplementary angles, hence:

m<1 + m<2 = 180º

As the sum of the measures of supplementary angles is of 180º.

Then these two angles are classified as consecutive interior angles, meaning that Maple Street and Elm Street are parallel lines cut by the transversal River Drive.

∠D = 127°

Step-by-step explanation:

Let's define the properties of a parallelogram to understand how to solve for ∠D.

⭐The opposite angles in a parallelogram are congruent.

⭐The sum of the interior angles of a parallelogram is 360°.

First, let's solve for x knowing that the opposite angles are congruent.

∠A = ∠C

[tex]13x - 25 = 9x - 1[/tex]

[tex]13x - 9x = 25 - 1[/tex]

[tex]4x = 24[/tex]

[tex]x = 6[/tex]

∴ x = 6

Next, substitute x into ∠C.

∠C = 9x - 1

∠C = 9(6) - 1

∠C = 54 - 1

∴ ∠C = 53°

Finally, substitute ∠C into the equation 2(∠D) + 2(∠C) = 360° to solve for ∠D.

2(∠D) + 2(∠C) = 360°

2(∠D) + 2(53) = 360

2(∠D) + 106 = 360

2(∠D) = 254

∴ ∠D = 127°
