[tex]{ \tt{ = \frac{5 - ( - 3)}{3 - ( - 1)} }} \\ \\ = { \tt{ \frac{8}{4} }} \\ \\ = 2[/tex]

Answer:

The table is linear because as x increases by 1, y changes by an average rate of |2|. You can also notice the tables both end in |+1|, which shows that the table has a constant rate of change between the two points at the end. Thus, the table is linear. If the table was nonlinear, there would be no constant rate of change between the 2 sets of data.

Given the equation 6y = 2x, y varies directly with x and the constant of variation k has a value of 1/3.

There are two kinds of variations: direct and inverse.

Direct variation is a linear function defined by an equation of the form y = kx where variable y varies directly as x. On the other hand, inverse variation is a nonlinear function defined by an equation in the form y = k/x where variable y varies inversely as x.

Transforming 6y = 2x into a function of y,

y = 2/6 x

y = 1/3 x

where k = 1/3

Notice that it resembles the form y = kx which describes a direct variation between x and y.

Hence, the equation 6y = 2x shows that y varies directly with x and k = 1/3.

The first fur terms of an arithmetic sequence are 4, 7, 10, 13

It is a series of numbers where the gap between succeeding phrases is always the same. for instance, 5, 7, 9, 11, 13, and 15. An arithmetic sequence's nth term is determined by the formula a = a + (n - 1)d.

Given, common difference = 3

third term = 10

formula of arithmetic sequence is an = a + (n-1)d

a3 = a + (3-1)3

10 = a + 6

a = 4

a1 = 4

a2 = a + (n-1)d

a2 =  4 + (1)3

a2 = 7

a4 = a + 3d

a4 = 4 + 3.3

The sequence is an arithmetic sequence with d = 25 and the next two terms are 125, 150.

Suppose we are given a sequence: a1, a2, a3, a4, ...

To determine whether the sequence is an arithmetic, geometric, or uncategorized one, we need to check the relation between its consecutive terms.

Arithmetic sequence.

If:

a2 - a1 = a3 - a2 = a4 - a3 = constant

then the given sequence is an arithmetic sequence. Furthermore, the constant d = a2 - a1  is usually called the common difference.

Geometric sequence.

If:

a2/a1 = a3/a2 = a4/a3 = constant

then the given sequence is a geometric sequence. Furthermore, the constant r = a2/a1  is usually called the common ratio.

The given sequence is:

25,50,75,100, ........

Let us check the difference:

50 - 25 = 75 - 50 = 100 - 75 = 25.

We can, then, conclude that the sequence is an arithmetic sequence with d = 25.

To find the next two terms, add 25 to every last terms.

100 + 25 = 125

125 + 25 = 150

Hence the next two terms are: 125, 150.

Answer:

1/30 of a ton of the rock was left at the construction site

Hope this helps :)

Explanation below.

Step-by-step explanation:

1. Make the same denominators to add them which is 6 (LCM).

1/3 + 1/2

2/3 + 3/6 = 5/6

2. Make the same denominator to subtract them since had to take back 4/5 of a ton. 30 would be the Least Common Multiple of 6 and 5.

5/6 - 4/5

25/30 - 24/30 = 1/30

Answer:

22425

Step-by-step explanation:

The equation that describes the total number of pages of the book read as a function of the number of minutes of further reading is; 2.67x minutes.

The time it will take to finish the whole 396 pages is; 113.3 minutes

We are told that the book has 396 pages. Now, the student has read 3/8 of this book.

Thus, number of pages the student has read so far = 3/8 * 396 = 148.5 pages

Now, let the time spent reading these 148.5 pages be x minutes. Thus;

Number of pages read per minute = 148.5/x pages per minute

Number of pages left to finish book = 396 - 148.5 = 247.5 pages

Thus, time to finish remaining pages = 247.5/(149.8/x ) = 1.67x

Thus, time it will take to finish the whole 396 pages = 1.67x + x = 2.67x minutes

The table showing the amount of pages that can be read for specific minutes is attached.

We see that 7 pages are read in two minutes. Thus;

x = (148.5 * 2)/7 = 42.42857 minutes

Thus, time to finish whole book = 2.67 * 42.42857 ≈ 113.3 minutes

Step-by-step explanation:

Alexi’s sister saved about 18.4 meters by swimming across the river.

In this question,

Alexi walks 27 meters south and 38 meters east to get around a lake. Her sister swims directly across the lake.

The south and east directions are perpendicular.

The distance across the south, east and across the river form a right triangle, with the distance across the river as hypotenuse of right triangle.

Let x be the distance across the river.

Using Pythagoras theorem,

27² + 38² = x²

729 + 1444 = x²

2173 = x²

x = 46.6

The distance saved would be the difference between the sum of the two legs of the triangle and the hypotenuse (distance across the river).

distance saved = (27+38) - 46.6

                          = 18.4

Therefore, Alexi’s sister saved about 18.4 meters by swimming across the river.

there is a pattern of x3 every time :)

The slope - intercept form of the equation x-2 y+3=1 is  y = x/2 + 1 .

Simply said, the slope-intercept form is the technique to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible. This form is frequently known as the y = mx + b form.

The slope - intercept form is y = mx + c

The given equation is

x-2 y+3=1

Subtract 3 from both sides,

x - 2y = -2

Divide the whole equation by 2

x/2 - y = -1

Rearrange the equation -

y = x/2 + 1

So the equation in slope-intercept form is y = x/2 + 1 , where slope is 1/2 and c = 1.

The equation of the line passing through the point (4 , -3)  and has a slope of 1/2 is H. y = (1/2)x - 5.

The equation of a line can be expressed in different forms: standard form, slope-intercept form, and point-slope form

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Given the slope of 1/2 and a point (4 , -3), use the point-slope form to generate the equation of the line by plugging in the values in the equation.

(y - y1) = m(x - x1)

y - -3 = 1/2(x - 4)

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

Isolating the variable y in the left side,

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

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

y = (1/2)x - 5

Drops of yellow pigment is 8.

A ratio is a comparison of two identical values that makes it simple to compare them. This is how a fraction with a numerator and denominator comparison is expressed. Depending on the ratio formula employed in various parts of mathematical computation, the definitions of the numerator and denominator may change.

For a certain shade of green, y = yellow and b = blue, where y/b = 2/3.

How many yellow drips are needed if there are 12 drops of blue,

y/b = 2/3 = x/12

= 2 × 12 = 3 × x

= 24 = 3x

= 24/3 = x

= x = 8

If you have 12 droplets of blue, you will need 8 drops of yellow.

y/b = 2/3

y = 2/3 × b

Substituting the value b = 12

y = 2/3 × 12

y = 24/3 = 8
