Answer:

Kindly check explanation and attached picture

Step-by-step explanation:

Given the time-series data:

Time (x) : 1 - - 2 - - 3 - - - 4 - - - 5

Data (yt) :6 - - 11 - - 9 - - 14 - - 15

The pattern which exists within the data is a linear pattern which could be inferred through the observable decrement and Incremental change in the y values at a steady or constant rate with time. The second attachment shows the linear trend line of the data.

The answer is c (4, 1) because when you add 1 to the x value it moves right one and then when you subtract 3 from the y value it goes down 3 making it (4, 1)

Jayce is a taxi driver

erastovalidia [21]

Answer:

Jayce's fee for his $10^{th}$ drive is equal to $K$ dollars.

Step-by-step explanation:

$M(n)$ models Jayce's fee (in dollars) for his $n^{th}$ drive on a certain day.

Substitute $n=10,$ then

$M(10)$ models Jayce's fee (in dollars) for his $10^{th}$ drive on a certain day.

This means Jayce's fee for his $10^{th}$ drive is equal to $K$ dollars.

Given: the function defined by f(x)=3x^2-4 Which statement is true? 1. f(0) = 0 2. f(-2) = f(2) 3. f(5)+ f(2) = f(7) 4. f(5) x f

sergeinik [125]

$f(x)=3x^2-4 \\ \Downarrow \\ f(0)=3 \times 0^2-4=0-4=-4 \\ -4 \not= 0 \\ f(0) \not= 0 \\
\hbox{statement 1 is false} \\ \\
f(-2)=3 \times (-2)^2-4 =3 \times 4-4=12-4=8 \\
f(2)=3 \times 2^2-4=3 \times 4-4=12-4=8 \\ 8=8
\\ f(-2)=f(2) \\
\hbox{statement 2 is true}$

$f(5)=3 \times 5^2-4=3 \times 25-4=75-4=71 \\ f(2)=8 \\
f(7)=3 \times 7^2-4=3 \times 49-4=147-4=143 \\
71+8 \not= 143 \\
f(5)+f(2) \not= f(7) \\ \hbox{statement 3 is false} \\ \\
f(5)=71 \\ f(2)=8 \\ f(10)=3 \times 10^2-4=3 \times 100-4=300-4=296 \\
71 \times 8 \not= 296 \\
f(5) \times f(2) \not= f(10) \\
\hbox{statement 4 is false}$

Stamement 2. f(-2)=f(2) is true.

PLEASE HELP ME!! I DO NOT UNDERSTAND PLEASE SHOW WORK THANK YOU!!

Oksanka [162]

Answer:

= 10x² + 9x³

Step-by-step explanation:

I'm assuming you mean question 19

3x² + 5x³ + 7x² + 4x³ (rearrange to group like terms)

=3x² + 7x² + 5x³ + 4x³ (factor out common powers)

= (3+7)x² + (5+4)x³

= 10x² + 9x³
