Answer:

He bought 2 notebooks

Step-by-step explanation:

Add up the cost of the pens, pencils, sharpeners, and the change.

This will give you £4.80, subtract that from £7.00 and you get £2.20

Since the notebooks are only £1.10, he could've only bought 2.

The points to be graphed are (0, 1) and (-0.2, 0). The graph of the equation is shown in the attached image

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

In order to graph the equation of the line:

First, find the value of x when y = 0:

y-2=1/5(x-5), when y = 0:

0 -2 = 1/5(x-5)

-2 = 1/5x - 1

1/5x = -2 + 1

1/5x = -1

-5x = 1

x = -1/5 = -0.2

Also, find the value of y when x = 0:

y-2= 1/5(x-5), when x = 0:

y-2= 1/5(0-5)

y-2 = 1/5(-5)

y-2 = -1

y = 1

Therefore,  the values to be plotted on our graph are (0, 1) and (-0.2, 0). The image of the graph is attached

(a) The equation of the parallel line is y = 3x - 11.

(b) The equation of the perpendicular line is y = - x/3 - 1.

Consider the line graphed,

The two points on the line are ( 1, - 4 ) and ( 2, - 1 ).

Now, the slope of the line with two points ( x₁, y₁ ) and ( x₂, y₂ ) is:

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Then,

m = ( - 1 - (-4) ) / ( 2 - 1 )

m = 3

(a) The lines which are parallel have the same slope.

Now, the parallel line passes through ( 3, - 2 ).

Therefore, the equation of the line is y = mx + b where b is the y-intercept.

y = mx + b

- 2 = 3 × 3 + b

- 2 = 9 + b

b = - 11

Therefore, the equation of the line is y = 3x - 11.

(b) The slope of the line perpendicular to the line with slope m is equal to - 1/m.

Then the slope of the perpendicular line is - 1/3.

The line passes through the point ( 3, - 2 ).

y = mx + b

- 2 = ( - 1/3 ) × 3 + b

- 2 = - 1 + b

b = - 1

Then the equation of the perpendicular line is:

y = - x/3 - 1

a) The slope of the equation is m = 291.5

b) The y intercept is y = 2944.01

An intercept in mathematics is a location on the y-axis through which the line's slope passes. It is a place on the y-axis where a straight line or a curve crosses. This is reflected in the equation for a line, which is written as y = mx+c, where m denotes slope and c denotes the y-intercept.

Given : y = 291.5x + 2944.01

and x = number of years after 2000

y = total cost

a) The given equation is of the form y = mx + c

On comparing these two equations , we get that the slope m = 291.5

b) The y intercept is y = 2944.01

The y intercept means the value of the y when x = 0 .

Thu when we substitute the value of x as 0

we get y = 2944.01

Integer represents the change in the height of the elevator, in meters, every second is 25200.

The speed at which an object's location changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

Given Data

The main elevator in the Willis Tower descends 420 meters in 60 seconds.

Distance = 420meters

Time = 60 seconds

Speed = distance (time)

True

Step-by-step explanation:

The line doesn't go through the origin (0, 0). Therefore, it does not have a constant of proportionality. (even though it has a constant slope)

Also, it's a trick question. The answer is false because the statement is a negative.

After solving the arithmetic sequences, he lengths of the first four segments will be 20 cm.

Arithmetic sequences take the following format: a, a+d, a+2d, a+3d, etc. up to n terms. A is the first term; d is a frequent difference; and n is the total number of terms.

Find the AP, the number of terms, and the common difference for the calculation using the arithmetic sequence formulas. To determine the nth term, sum, or common difference of a given arithmetic sequence, various arithmetic series formulas are used.

To find the lengths of the first four segments we use the Arithmetic progression formula that is

[tex]a_n =[/tex] a₁ + (n - 1)d

Where

an = the nᵗʰ term in the sequence

a₁ = the first term in the sequence

d = the common difference between terms

We have a₁ as 5 cm and as it is being duplicated the common ration d is 5

and we have been asked the length of the first four segments, so n = 4

Lets substitute the given information

[tex]a_n =[/tex] 5 + (4 - 1)5

    = 5 +(3)5

    = 5 + 15

    = 20

Thus, after continually duplicated segment ab, the lengths of the first four segments will be 20Cm

Step-by-step explanation:

To make the equation have infinitely many solutions, we need to make both sides equal.

i will use variable y in place of blank

-x + 20 + yx = -4x + 20

-x + yx = -4x

yx = -3x

y = -3

now we can check the answer

-x + 20 - 3x = -4x + 20

-4x + 20 = -4x + 20

0 = 0

The true statement about the end behaviour of the described function is the fourth option;

The end behaviour of a function is the description of the shape of the function's graph towards the left and right extremities of the x–axis

The points on the graphed function, obtained from the description are;

Minimum point; (-1.25, -3.25)

Maximum point; (0.25, -1.75)

x–intercept; (-2.25, 0)

y–intercept; (0, -2)

Exit points of the graph on the plane; (-2.75, 6), and (1.5, 6)

Arranging the above points with respect to their location on the x–axis gives;

(-2.75, 6), (-2.25, 0), (-1.25, -3.25), (0, -2), (0.25, -1.75), (1.5, 6)

Observing the y–values indicates that the y–values decreases in the region; -2.75 ≤ x < -1.25, and the y–values increases in the region; -1.25 < x ≤ 1.5

Which gives;

The turning point on the graph are the points (-1.25, -3.25) and (0.25, -1.75)

However, as the x–values increases towards+1.5, the y–value increases to 6

The correct option is therefore;

As the x–value go to positive infinity, the function value goes to positive infinity

The right way to write digit 182136 without knowing the other factor is by; moving the decimal points 3 places to the left.

It is given that the digits in the product of 0.48 and a decimal number between 350 and 400 are 182136. Note that 0.48 is simply 48/100.

Hence, consider the decimal number between 350 and 400. The number will include one decimal place, so if it's 350.1, we may express it as 3501/10.

When we multiply 48/100 by 3501/10, the denominator is 1000, which is three decimal points to the left of the result.

As a result, the right method to express the answer supplied to us is 182.136, which was accomplished by shifting the decimal point three spaces to the left.
