calc three
linear algebra

Answer 7

no hurry

Answer 12

that is not algebra, that is arithmetic

Answer 13

whats that.

Answer 14

you know, stuff with numbers instead of variables
do you know how to do long division?

Answer 15

i hope so because it is impossible to write long division here

Answer 16

um i use mathway

Answer 17

well i can just tell you that the remainder is 6, because \[9712=211\times 46+\color{red}6\]

Answer 18

ok so im right

Answer 19

if im right u dont need to explain

Answer 20

you know how to set up a long division problem?
yes, you are always right

Answer 22

right again

Answer 24

idk

Answer 25

ok so now we learn something

Answer 26

thank god that ugly guy left'
in any case you have to factor, because that is what is says to do

Answer 27

ok

Answer 28

we got \[x^2-3x-28=0\] and we want to factor it
do you know what that means?

Answer 29

put on the x's and one with no x's together

Answer 30

idk

Answer 31

it meant to write it as a product , like \[(x+5)(x-4)\] or something like that
that is not the answer, that is just what it will look like

Answer 32

how do i put it like that

Answer 33

you first have to think of two numbers that multiply to get \(-28\)
pretty clearly one has to be positive and one has to be negative
can you think of two numbers that whose product is \(-28\)?

Answer 34

um

Answer 35

4 x -7

Answer 36

try
i can tell you one, \(-1\) and \(28\) since \(-1\times 28=-28\) see if you can...
ok got it

Answer 37

now we are not done yet, you have to check if \[4+(-7)=-3\] which is does

Answer 38

that means \[x^2-3x-28=(x+4)(x-7)\]
if \[(x+4)(x-7)=0\] then either \[x+4=0\] so \[x=-4\] or \[x-7=0\] so \[x=7\]

Answer 39

then c or a

Answer 40

your two answers are therefore \[\{7,-4\}\]

Answer 41

no not C or A, only C has that pair

Answer 42

not c but its c??

Answer 43

it is C, yes

Answer 45

as x goes to infinity, that means x is going to the right
it should be clear from your eyeballs that as x goes to the right, the curve is headed downward
to as x goes to infininity, f goes to \(-\infty\)

Answer 46

oh they right it in words
as x goes to infinity, \(f(x)\) goes to minus infinity
and as x goes to minus infinity (you are headed to the left) the curve is going up
so as x goes to minus infinity, \(f\) goes to plus infinity

Answer 47

so confusing

Answer 48

so as x goes to the right, \(f(x)\) is going down
i.e. as \(x\) goes to infinity, \(f(x)\) goes to minus infinity

Answer 49

do u mean negative infinity?

Answer 50

so as x goes to minus infinity \(f(x)\) goes to plus infinity

Answer 51

minus infinity, negative infinity, same thing

Answer 52

d?

Answer 53

C
