Answer:

a) 3, 6, 9, 12, 15,...,[tex]3\cdot n[/tex], b) 4, 7, 10, 13, 16,...,[tex]3\cdot n +1[/tex], c) Both sequences are arithmetic.

Step-by-step explanation:

a) The sequence of natural numbers which are multiplied by 3 are represented by the function [tex]f(n) = 3\cdot n[/tex], [tex]n\in \mathbb{N}[/tex]. Let see the first five elements of the sequence: 3, 6, 9, 12, 15,...

b) The sequence of natural numbers which are multiplied by 3 and added to 1 is represented by the function [tex]f(n) = 3\cdot n + 1[/tex], [tex]n\in \mathbb{N}[/tex]. Let see the first five elements of the sequence: 4, 7, 10, 13, 16,...

c) Both sequences since differences between consecutive elements is constant. Let prove this statement:

(i) [tex]f(n) = 3\cdot n[/tex]

[tex]\Delta f = f(n+1) -f(n)[/tex]

[tex]\Delta f = 3\cdot (n+1) -3\cdot n[/tex]

[tex]\Delta f = 3[/tex]

(ii) [tex]f(n) = 3\cdot n +1[/tex]

[tex]\Delta f = f(n+1)-f(n)[/tex]

[tex]\Delta f = [3\cdot (n+1)+1]-(3\cdot n+1)[/tex]

[tex]\Delta f = 3[/tex]

Both sequences are arithmetic.

Answer:

y = 1/2x + 1

Step-by-step explanation:

slope-intercept form: y = mx + b

If you have a slope of 1/2, m = 1/2

y = 1/2x + b

To find b, plug in the known point.

4 = 1/2(6) + b

Solve.

4 = 3 + b

b = 1

Plug b into your equation.

y = 1/2x + 1

Answer: Chicken nuggets in zip loc bag?

Step-by-step explanation:

Complete question :

A lake near the Arctic Circle is covered by a 3 meter thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After four weeks, she is only 1.6 m thick. Let S(t) denote the ice sheet's thickness S (measured in meters) as a function of time t (measured in weeks). Write the function's formula

Answer:

S(t) = 3 - 0.3t

Step-by-step explanation:

Given that:

Initial thickness = 3m

Assume the rate of decrease is constant

Thickness after 4 weeks = 1.6 m

To obtain a function for the scenario described above :

We can observe that the function is a linear function, given that rate of decrease per week is constant :

To obtain the rate of decrease :

Change after 4 weeks :

(Initial thickness - thickness after 4 weeks) / number of weeks

(3m - 1.6m) / 4

= 1.2m / 4

= 0.3 m per week

General form of a linear function :

y = mx + c

m = rate of change per unit

Hence, our function becomes ;

S(t) = 3 - 0.3t

Answer:

The equation of the line is:

y = 2/3x - 3

The graph is also attached below.

Step-by-step explanation:

From the given diagram, let us take two points

(0, -3)

(4.5, 0)

Determining the slope between (0, -3) and (4.5, 0)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:-3\right),\:\left(x_2,\:y_2\right)=\left(4.5,\:0\right)[/tex]

[tex]m=\frac{0-\left(-3\right)}{4.5-0}[/tex]

[tex]m\:=\frac{3}{4.5}[/tex]

[tex]m=\frac{3}{\frac{45}{10}}[/tex]

[tex]m=\frac{3\cdot \:10}{45}[/tex]

[tex]m=\frac{2}{3}[/tex]

Therefore, the slope of the line is:

m = 2/3

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the given point

It is clear that at x = 0, the value of y = -3

Thus, the y-intercept b = -3

now substituting b = -3 and m = 2/3 in the slope-intercept form of the line equation

y = mx+b

y = 2/3x + (-3)

y = 2/3x - 3

Therefore, the equation of the line is:

y = 2/3x - 3

The graph is also attached below.

Answer:

f(x) = 1/3x + 1

Step-by-step explanation:

slope-intercept form is

f(x) = mx + b

so just put the points in and you have:

f(x) = 1/3x + 1

also b stands for the y-intercept so if you look at your point (9,1) than your y-intercept would be 1.

hope I could help!!

Correct choice is (4) 20

Answer:

$30

Step-by-step explanation:

6 box = 18

1 box = 3

10 box = 30

Answer:

the length is 22 and the width is 18

Step-by-step explanation:

The perimeter is 2(l) + w(2)

w is the width and l is the length

if you plug in 22 and 18 you get

2(22)+(2)18

then you do multiplication to get

44+36

then you add and you get 80

Step-by-step explanation:

The point (5, 13) is a solution to the system

The system of equations is given as:

[tex]y = 4x - 7[/tex]

[tex]2x + y = 23[/tex]

The solution is given as: (5,13)

To determine if the coordinate point is a solution of the system of equations, we have to substitute the x and y values in the equations.

So, we have:

[tex]y = 4x - 7[/tex]

[tex]13 = 4 \times 5 - 7[/tex]

[tex]13 = 13[/tex]

[tex]2x + y = 23[/tex]

[tex]2 \times 5 + 13 = 23[/tex]

[tex]10+ 13 = 23[/tex]

[tex]23 = 23[/tex]

The above equations are true.

Hence, the point (5, 13) is a solution to the system
