Question

my final two questions 2x+3y+3z=5 4x+5y+3z=13 use matrices and the other is find the sum of the infinite geometric series: 9,-6+4... choices for the first A.(5,13,13) b.(2,4,3) c.(1,2,-1) d.(1,3,-2)the choices for the second question are a.2/3 b.4//9 c.5 d.27/5

Answer 1

2x+3y+3z=5
4x+5y+3z=13

Is there supposed to be a third equation with these two?

Answer 2

nope it only gave me two weird

Answer 3

Well, what are the instructions? I don't know what you are supposed to do with the two equations.

Answer 4

oh yea forget that question use the factor theorem to determine if (x-1) is a factor of x^3+x^2-16x-16? a.factor b.not factor

Answer 5

>>oh yea forget that question Which question should be forgotten?

I am totally mixed up as to whether you are asking 3 questions or what.

I really wish you would post exactly one question per thread.

Answer 6

never in my life have i heard of a factor theorem my teacher is retarded

Answer 7

forget about this question the solving the matrices one cause i dont have the three equations

Answer 8

Take this: x^3+x^2-16x-16 and evaluate it for 1.

1^3 + 1^2 - 16 * 1 - 16 = ?

Answer 9

so would the anwser be 16

Answer 10

Definition of Factor Theorem
•According to Factor Theorem, if s is the root of any polynomial P(x), i.e. if P(s) = 0, then (x - s) is the factor of the polynomial P(x).

Answer 11

1^3 + 1^2 - 16 * 1 - 16 =

1 + 2 - 16 - 16 = -29

Answer 12

So, (x - 1) is not a factor of x^3+x^2-16x-16

Answer 13

find the sum of the infinite geometric series: 9,-6+4...

Answer 14

Is this supposed to be: 9 ,-6, 4... instead of 9,-6+4...

Answer 15

nope thats how it was given

Answer 16

There is something wrong with this: 9,-6+4...

See what it is.

A series should look like this: 9 - 6 + 4 --> No commas.

Answer 17

oh i must of wrote it wrong that looks write

Answer 18

I wonder if this is correct: 9 - 6 + 4

What do you think the cm is?

Answer 19

these are my choices a.2/3 b.4/9 c.5 d. 27/5 i think its 5

Answer 20

not sure

Answer 21

Is the series arithmetic, geometric, or something else?

I wish you had the textbook so that you could check to see if you copied the problems correctly.

Answer 22

If a sequence of values follows a pattern of adding a fixed amount from one term to the next, it is referred to as an arithmetic sequence. The number added to each term is constant (always the same).

The fixed amount is called the common difference, d, referring to the fact that the difference between two successive terms yields the constant value that was added. To find the common difference, subtract the first term from the second term.

Answer 23

just forget it can you help me with this one and we will call it even

Answer 24

im so sorry for the confusion

Answer 25

I don't see a common ratio. I don't see a common difference so the formulas for finding the sum cannot be applied.

Answer 26

Which problem are we doing now?

Answer 27

forget the sequence just can you help me with this one it asks what is the system of equation that describes the graph

Answer 28

and well call it done

Answer 29

cause i have to sleep

Answer 30

Post it here and now. Let's do it.

Answer 31

@Karina1

Answer 32

what is the equation of the following graph? A.(y+3)^2/2-(x-1)^2=1
B.(y-3)^2/4-(x-1)^2/2=1 C.(y+3)^2/4-(x-1)^2/2=1 D.(y+1)^2/4-(x-3)^2/2=1

Answer 33

i suck a t drawing
