Question

check my answer

Answer 1

What is the slope of the line which passes through (1, 4) and (0, 1)?

3
-3
4
-2

Answer 2

\[\frac{ y_2 - y_1 }{ x_2 - x_1 } = \frac{ 1 - 4 }{ 0 - 1 } = \frac{ -3 }{ -1 }\]

Answer 3

so 3 is my choice

Answer 4

yep

Answer 5

Correct!

Answer 6

i have mote do you mind checking?

Answer 7

sure

Answer 8

NOT AT ALL!

Answer 9

whoops caps

Answer 10

yep that's right thanks for the work!

Answer 11

What is the 2nd term when 5y^3 + 2y - 3 + 6y^2 - y^4 is arranged in descending order?

5y^3 <--- my choice
2y
6y^2
-y^4

Answer 12

highest to lowest degree
5 ,4,3,2,1,constant

Answer 13

because i rearranged it as \[-y^4 + 5y^3 + 6y^2 + 2y -3\]

Answer 14

Correct! The first is 6y^2, second your choice!

yep :-)

Answer 16

i meant +5y^3

Answer 17

okay thanks

Answer 18

Hey, would any of you mind helping me with my problem? It's for my homework this summer, and I'm trying to finish it so I can check it with my best friend whose taking the course.

Answer 19

Which of the following is the conjugate of a complex number with 4 as the real part and -3 as the imaginary part?

-3 + 4i
3 - 4i
4 + 3i
4 - 3i

Answer 20

this one idk the answer to

Answer 21

4 is the real part
and -3 is imaginary
so \[\huge\rm 4 - 3\color{red}{i}\]
conjugate change the sign of imaginary part

Answer 22

oh okay thnx

Answer 23

Given f(x) = (x - 7)/(3), solve for f-1(4).

-1
19 <--- my choice
33
37

Answer 24

\[f(x) = \frac{ x - 7 }{ 3 } \]
\[y = \frac{ x - 7 }{ 3 }\]
\[x = \frac{ y - 7 }{ 3 }\]
\[3x = y - 7 \]
\[y = 3x + 7\]
\[y = 3(4) + 7 \] \[12 + 7 + 19\]

Answer 25

yep right

Answer 26

yay

Answer 27

Factor 4x^2 - 4x - 24 completely.

4(x - 3)(x + 2) <--- my choice
4(x + 3)(x - 2)
(4x + 3)(x - 2)
(4x - 3)(x + 2)

Answer 28

i used a factoring calculator b/c idk how to factor on my own

Answer 29

first of all find GCF(greatest common factor )

Answer 30

4

Answer 31

yes right take it out
4(???????)
divide all 3 terms by GCF which is 4 write your answer in the parentheses

Answer 32

x^2 - x - 6

Answer 33

sorry forgot to write them in parenthesis

Answer 34

\[\huge\rm 4(x^2 - x - 6)\]
now find two number if you multiply them you should get product of AC
and if you add or subtract them you should get middle term B
abc are Ax^2 +Bx+C

Answer 35

idk 2 and 3

Answer 36

\[\huge\rm 4(x^2 - x - 6)\]\[ \huge\rm Ax^2 +Bx+C\]
remember there is invisible one 1x^2
so
a= what
c= ?

Answer 37

a = 1 and c = -6

Answer 38

yes right
so a times c = ?

Answer 39

-6

Answer 40

yes so 2 times 3 is not equal to -6
which one should be negative 3 or 2 ?
remember when you add or subtract them you should get middle term

Answer 41

\[\huge\rm 4(x^2 - x - 6)\]\[ \huge\rm Ax^2 +Bx+C\]
middle term is b which is -1

Answer 42

-3

Answer 43

ye right so bec leading coefficient is 1 that's why just both number with
(x+ first number )(x +2nd number )

Answer 44

done!

Answer 45

thnx im going to practice it later to get better at it

Answer 46

great!
gO_od luck!

Answer 47

thnx

Answer 48

What is the equation in point-slope form of the line passing through (-3, -4) and (0, 2)?

(y - 8) = 2(x - 3) <-- my choice
(y + 3) = -2(x + 4)
(y - 2) = -2(x + 4)
(y + 4) = 2(x + 3)

Answer 49

what is the general form of point slope ?

Answer 50

equation *

Answer 51

(y - y1) = m(x - x1)

Answer 52

yes right now pick one of order pair substitute y_1 and x_1 value

Answer 53

y + 4 = m(x +3)

Answer 54

yes right there is a negative sign in the formula and x and y values are also negative so it becomes positive 4 and 3 that's right

Answer 55

oh so D

Answer 56

yes

Answer 57

okay the next one idk

Answer 58

Simplify 2 times the 3rd root of 108 .

16 times the 3rd root of 18
8 times the 3rd root of 6
5 times the 3rd root of 4
6 times the 3rd root of 4

Answer 59

factor 108 one of number must be perfect cube root

Answer 60

what

Answer 61

what are factor of 108?

Answer 62

idk

Answer 63

start dividing 108 by 2

Answer 64

54,

Answer 65

do i devide 54 by 2 too?

Answer 66

yes right

Answer 67

54 is divisible by 2 so yes divide
