Answer:

You solve equations algebraically by using equations to answer and having variables rather than the arithmetic way (doing the work).

Ex: instead of 20÷5=4 (arithmetic), you do

20=5x

A. Yes the table represents a proportional relationship

B. The constant of proportionality is 1.2

Step-by-step explanation:

Two quantities are proportional if:

∵ Total wight in pounds ⇒ 12  ,  18  ,  30  ,  60

∵ Number of books ⇒ 10  ,  15  ,  25  ,  50

- Divide each two corresponding data to check if all they give

   the same constant or not

∵ 12 ÷ 10 = 1.2

∵ 18 ÷ 15 = 1.2

∵ 30 ÷ 25 = 1.2

∵ 60 ÷ 50 = 1.2

- That means the total wight is equal to constant times the

   number of books

∴ Total wight = 1.2 Number of books

∴ The total wight and the number of books are in a proportional

    relationship

A. Yes the table represents a proportional relationship

∵ Total wight = 1.2 Number of books

∴ The constant of proportionality = 1.2

B. The constant of proportionality is 1.2

Answer:

The slope of straight line in the graph is

m = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Slope of a given line is [tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} }[/tex]........(1)

The point (-2,0) lie on x-axis in the graph and another point ( 0, 1) lie on y- axis.

so [tex](x_{1} , y_{1}) = (-2,0) and (x_{2} , y_{2}) = (0,1)[/tex]

substitute these values in equation (1)

[tex]m = \frac{1-0}{0-(-2)}[/tex]

[tex]m = \frac{1}{2}[/tex]

slope of given line is [tex]m = \frac{1}{2}[/tex]

Answer:q= (2C - fb)/f

Step-by-step explanation:

multiplying both sides by 2 we have,

2C = fb + fq,

subtract both sides by fb

fq = 2C - fb,

dividing both sides by f

q= (2C - fb)/f

Answer:

A. 25°

Step-by-step explanation:

We are given a circle and two intersecting lines of circle meets at s and form an angle 34° at S.

Also, we have W and X points on circle that form a minor arc and T and R makes a major arc of angle 93°.

In order to find the value of minor arc WX, we need to apply following formula:

Subtends angle on intersection of lines  =  [tex]\frac{Major Arc- Major Arc} {2}[/tex]

Plugging values in above formula, we get

34= [tex]\frac{93 - x }{2}[/tex]

On cross multiplication, we get

34 × 2 = 93-x

68 = 93 -x

x = 93-68

x= 25.

Non-vertical parallel lines have equal slopes, while slopes of non-vertical, non-horizontal perpendicular lines are negative reciprocals of each other. Vertical lines are defined as having an infinite slope, thus they must be non-vertical to consider their slopes.

When considering the slopes of lines on a graph with perpendicular axes, like the x-axis and the y-axis, we can draw several conclusions about parallel and perpendicular lines. If two non-vertical lines are parallel, their slopes are equal, because the tilt of the lines with respect to the horizontal axis is the same. For example, if we have two equations of lines in the form y = mx + b, where m represents the slope and b represents the y-intercept, parallel lines would have the same value of m.

If two lines are perpendicular and neither line is parallel to an axis, then their slopes are negative reciprocals of one another. This holds true because the product of the slopes of two perpendicular lines is -1. For example, if the slope of one line is a, the slope of the line perpendicular to it will be -1/a.

It is necessary for the lines to be non-vertical because a vertical line does not have a well-defined slope; its slope is considered infinite. Therefore, the definition of perpendicular lines in terms of slope only applies to non-vertical lines.

Answer:

Step-by-step explanation:

No. of white bands = 15% of 360 = (15/100)*360= 54

No.of red bands = 360 - 54 = 306

No. bands remaining = 360 - 140 = 220

No. of remaining white bands = 20% of  220= (20/100)*220 = 44

No. of remaining red bands = 220 - 44 = 176

No. of red band used = No.of red bands - No of remaining bands

= 306 - 176 = 130

A function from x to y represents a situation where each x value is linked to a unique y value. This can be represented in a mapping diagram, such as with the points (1,5), (2,10), (3,7), and (4,14). Such a diagram showcases the fact that different x values trigger different y values, demonstrating the dependence of y on x.

A function from x to y implies that when the value of x changes, it directly influences the value of y. One way to represent this is through a mapping diagram.

A mapping diagram that represents a function can be visualised as each value of x corresponding to a unique value of y. For example, refer to the following points: (1,5), (2,10), (3,7), and (4,14). Here, every x value is paired with a unique y value. When these points are plotted, there's no x value that corresponds to more than one y value, demonstrating the dependence of y on x.

Therefore, a function from x to y is represented by a mapping diagram where different x values are linked to unique y values, showing the dependency of y values on the x values.

Answer:

Step-by-step explanation:

Given function is [tex]6x^2+7x-49[/tex]

We will find its root by factoring.

In any quadratic function of the form [tex]ax^2+bx+c[/tex]

We will two numbers that when multiplied gives [tex]ac[/tex]. And when that two numbers are added it turns to [tex]b[/tex].

So, in [tex]6x^2+7x-49[/tex].

[tex]a=6,\ b=7.\ c=-49[/tex]

And [tex]ac=-294[/tex]

So, we need to find two numbers that when multiplied give [tex]-294[/tex],and when added give [tex]7[/tex].

Now, we can see

[tex]-14\times21=-294\\And\ -14+21=7[/tex]

In this manner, we can rewrite [tex]7x[/tex] as [tex]-14x+21x[/tex].

Final answer:

The expression (889 x 27) + 50 is greater than 889 x 27, because adding 50 to any product will always result in a larger number.

Explanation:

The student's question is asking to compare the result of the expression (889 x 27) + 50 with 889 x 27, without actually calculating the precise values.

First, let's evaluate the structure of the expressions. When we have an expression of the form (a x b) + c, adding any number c to the original product of a and b will always result in a value greater than the original product. This is a basic property of arithmetic progression.

Based on this property, we know that (889 x 27) + 50 is definitely greater than 889 x 27 because we are adding a positive number (50) to the original product, hence the sum must be larger.

Answer:

1)B:63°

2)A:59°

Step-by-step explanation:

1.ABC is a right triangle at C then angle ACB=90°(right angle)

Angle CAB=27°(see the given)

measure of the angles in any triangle is 180°

then angle CBA=

measure of all the angles - (measure ACB+measure CAB)

=180°-(90°+27°)

2. Same explanation of angle B:

in the right triangle DEF: angle DEF=90°

angle D=31°(given)

Then measure of angle A=180°-(angle E + angle D)

The dot plot for the considered data is plotted based  on how many times each observation occured (given by frequencies), as plotted in the image attached.

Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing we did.

Thus, suppose if we observed the value 'x', then we will make a dot above 'x'. If there is already a dot over 'x', then we will make a new dot over that dot.

If instead of only observations, the table of unique observation and frequency is given, then we plot dots that many times as the count written in the frequency table.
Thus, if its written that the value 2 has 3 has its frequency, then we plot 3 dots one over the other above the value 2 in the horizontal axis.

For this case, we're given the unique observation to frequency table as:

Diameter (cm)          Frequency

2                                       3

2.25                                  3

2.5                                    4

2.75                                  4

3                                       2

3.5                                   2

That means, over the value 2, plot 3 dots (as diameter 2 occured 3 times), and so on, over the value 3.5, plot 2 dots.

The dot plot of the considered data is attached below.

Answer:

The slope is -3

Step-by-step explanation:

Hello!

Slope is measured by lattice points on the graph, and the formula is Rise/Run.

To calculate the slope of this graph, we must find two points that intersect coordinates. I will choose coordinates (0,2) and (1,-1).

Now to find the rise, we must find the difference in the y coordinates.

To find the run, we must find the difference in the x coordinates.
