Question

What is the equation of a vertical line passing through (–4, –3)?

Answer 1

x = –4

y = –4

x = –3

y = –3

Answer 2

@ivettef365

Answer 3

value for x = vertical
value for y = horizontal

Answer 4

so it is vertical and what is the value of x

Answer 5

you have (x,y) point (-4,-3)

Answer 6

ok :) i got to that part, but which one do i pick?

Answer 7

@ivettef365

Answer 8

what is the x value on point (-4,-3) ??

Answer 9

-4

Answer 10

ok so x = -4

Answer 11

Simplify (x – 4)(x2 – 2x – 3)

Answer 12

how about this one?

Answer 13

@ivettef365

Answer 14

you need to multiply as follows:

x(x^2-2x-3)-4(x^2-2x-3)

Answer 15

i only have like 5 more questions. can you help witht them?

Answer 16

sure

Answer 17

can you solve the above equation

Answer 18

x3-6x2-3x - 4x2-8x-12?

Answer 19

x3 – 6x2 + 5x - 12

Answer 20

?

Answer 21

multiply (2sqrt3+3)(3sqrt3-5) <---- another one

Answer 22

x3 – 6x2 + 5x + 12 or this?

Answer 23

x^3 -2x^2 -3x -4x^2 +8x +12

Answer 24

x3 – 6x2 + 5x + 12 so this one?

Answer 25

correct

Answer 26

you should be the one getting all the metals. you always help

Answer 27

multiply (2sqrt3+3)(3sqrt3-5)
@ivettef365

Answer 28

ok 2\(\sqrt{3}\) . 3\(\sqrt{3}\) = 6.3 = 18
2\(\sqrt{3}\) . (-5) = -10\(\sqrt{3}\)
(3) . 3\(\sqrt{3}\) = 9\(\sqrt{3}\)
(3) . (-5) = -15

Answer 29

so you have

18 - 10\(\sqrt{3}\) + 9\(\sqrt{3}\) -15

Answer 30

can you take it from there

Answer 31

:/

Answer 32

just combine like terms

Answer 33

3- sqrt3

Answer 34

correct

Answer 35

Choose the system of equations which matches the following graph.

Answer 36

x + 2y = 4
3x – 6y = 18

x – 2y = 4
3x + 6y = 18

x + 2y = 4
3x + 6y = 18

x – 2y = 4
3x – 6y = 18

Answer 37

wont they be negative?

Answer 38

it can not be a, because when you convert to y = mx + b, where m = slope
you can see that both lines have negative slope and are parallel, so the slope needs to be negative and the same.

you have on a) x + 2y = 4
2y = -x + 4
y = -1/2x +2

and 3x - 6y = 18
-6y = -3x + 18 (divide by -6) you have
y = 1/2 x - 3

one have slope of -1/2 the other slope of 1/2 not good

Answer 39

d then

Answer 40

no, lets try c

x + 2y = 4
2y = -x + 4
y = -1/2x + 2 (y-int = 2) negative slope is good

3x + 6y = 18
6y = -3x + 18
y = -1/2x + 3 (negative slope, same slope, y-int = 3) is good

Answer 41

oh ok :) im so dumb

Answer 42

no, you're not, is just a matter of practice

Answer 43

What is the slope of the line which passes through (–2, 0) and (0, 4)?
how about this

Answer 44

–2

0

2

Undefined

Answer 45

is it d

Answer 46

that is just using the slope formula

y2 - y1
------
x2 - x1

Answer 47

its undefined

Answer 49

it 2!

Answer 50

try this website, enter the points and see what you get

Answer 51

4/2

Answer 52

correct, which is 2

Answer 53

a couple more.

multiply x^5/6 x^3/4

Answer 54

@ivettef365

Answer 55

@hobbs978

Answer 56

when multiplying exponents, you need to add
so you have x^5/6 . x^3/4 so it is equal to x^(5/6 + 3/4)

Answer 57

x4/5

Answer 58

Simplify the expression

Answer 59

@ivettef365

Answer 60

5 3 5(2) + 3(3) 19
--- + ---- = ---------- = --------
6 4 12 12

SO IT IS X^19/12

Answer 61

not an option

Answer 62

are you sure you posted the right problem, you have

multiply x^5/6 . x^3/4

Answer 63

the next one you have \(\sqrt{-9}\) that is equal to 3i

Answer 64

so you have

3i
-------------
3 - 2i + 1 + 5i (combine like terms, what do you get)

Answer 65

4+3i

Answer 66

so the answer is

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

Answer 67

did you find out about the other problem ??

Answer 68

Simplify i37

Answer 69

i think its i
