Question

M-M-MEDAL: Just want you to check some questions to see if I got it right and maybe answer some other questions.

Answer 1

Choose the slope-intercept equation of the line that passes through the point (6, 4) and is parallel to y = one thirdx - 3.

y = 3x - 14

y = one thirdx + 2

y = -3x + 22

y = -one thirdx + 8

Answer 2

It MUST be B, right?

Answer 3

It is B

Answer 4

Thans, can you check another one for me, please? Thanks.

Answer 5

I'll try

Answer 6

Okay.

Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x) + 20?

The graph of y = f(x) will shift left 20 units.

The graph of y = f(x) will shift down 20 units.

The graph of y = f(x) will shift up 20 units.

The graph of y = f(x) will shift right 20 units

I chose C because I know that the y-intercept is the vertical part of the coordinate plane and positive is up.

Answer 7

I don't know how to do this one, sorry :[

Answer 8

It's okay. "-D

Answer 9

Anyone else?

Answer 10

@atlas @mathstudent55

Answer 11

since the line is parallel to y =(1/3)x -3 ; the slope of this line will remain the same
you can write the new line as y = (1/3)x +c

Answer 12

You know at least one point that this line passes through
So if you put the value of x and y from that point ->you can get c

Answer 13

Are we talking about C?

Answer 14

C. Pfft, sorry. I meant the second question.

Answer 15

b

Answer 16

no a

Answer 17

C is right in my opinion

Answer 18

Yeah, I think its C, too because it is the y-intercept...

Answer 19

You can do a simple test to find out..........let f(x) be a constant lets say 1 and see how y changes

Answer 20

Okay, I have this question that I have been looking at for too long:

The following function defines a recursive sequence.

f(0) = -4

f(1) = 12

f(n) = -3•f(n -1) - 2•f(n - 2); for n > 1

Which of the following sequences is defined by this recursive function?

-4, 12, -28, 60, …

-4, -12, -28, -60, …

-4, 12, -18, 54, …

-4, 12, -18, -54, …

Answer 21

Just keep on putting the value of n=1,2,3 and so on

Answer 22

in the function f(n)

Answer 23

Oh no, never mind. I think I know now...It is *-3, ight? Er, multiplying by -3. So 12 * -3 = -36...No, that is not the answer. GR.

Answer 24

you are leaving the 2nd term of f(n)

Answer 25

f(n) = -3•f(n -1) - 2•f(n - 2)

Answer 26

f(3) =-3*f(2)-2*f(1)

Answer 27

I think I simplified it to f(3) = -5 * f(2) * f(1)...

Answer 28

nope how can you do that??

Answer 29

Gr. -covers eyes- I did the like terms thingie. Sigh.

Answer 30

but there isn't any like term here..........

Answer 31

llllllllllllll.
Then I dont now how to do this.
