@Vocaloid @dude

Answer 2

yeah that should be it

Answer 4

how about this^ @Vocaloid

Answer 5

you'd have to solve each inequality and see which one gives you x < -0.5 as a result

Answer 6

C

Answer 7

correct?

Answer 8

yeah that's what i got too

Answer 9

Answer 10

any attempts to solve? as a hint start with 5x - 1 >= 9 and solve for x

Answer 11

x is 2

Answer 12

so its either A or B

Answer 13

remember we're not dealing with equal signs, we are dealing with inequalities

5x - 1 >= 9 gives us x>=2 so which is the only possible answer choice?

Answer 14

A

Answer 15

good

Answer 16

Answer 17

any ideas? you can generate one of the two inequalities by removing the absolute value sign

Answer 18

B?

Answer 19

good

Answer 20

Answer 21

any ideas? you need to split the inequality |x + 2.5| > 1.5 into its two components
x + 2.5 > 1.5
and
x + 2.5 < -1.5 and solve separately

Answer 22

A?

Answer 23

almost

since we have a > symbol the circles need to be open, so B is the better option

Answer 24

got it

Answer 25

any ideas? you just need to pick the point that's not within the blue part

Answer 26

D?

Answer 27

ohh okay

Answer 28

one question^

Answer 29

any attempts to solve 3x - 2y <= 6 for y?

Answer 30

can you try solving 3x - 2y <= 6 for y?

Answer 31

Answer 32

i didnt know how to type that lol

Answer 33

alright now can you try to find the graph that matches that solution? remember, since y >= the shading should be above the line

Answer 34

A?

Answer 35

hmm i think im not sure

Answer 36

remember, the shading needs to be above the line y = (3x/2) -3

Answer 37

D or B

Answer 38

getting there

between B and D, which blue line matches the equation y = (3x/2) -3?

Answer 39

y = (3x/2) -3 has a positive slope

between B and D which one has the positive slope?

Answer 40

D

Answer 41

good, so D is the only possibility.

Answer 42

kk

Answer 44

any ideas? just look at the dotted blue line and identify the slope and y-intercept

Answer 45

Well, she's offline but
1) What is your y-intercept?
2) What is your slope?

Answer 46

umm

Answer 47

Oh, hi there.

(Anyway -- remember \(y=mx+b\))

Answer 48

Hello lol

Answer 49

C or D

Answer 50

negative 1 correct

Answer 51

I think its D

Answer 52

Slope is rise over run in the right-hand direction, so point 2 should be further right on the line than point 1:\[\large{m=\frac{y_2-y_1}{x_2-x_1}}\]

Answer 53

Ah, no... you got the slope backwards ^^'

Answer 54

B?

Answer 55

You said C or D lol

Answer 56

The y-intercept "b" in \(y=mx+b\) is still negative 1

Answer 57

Ohh I accidentally did it backwards

its not 5/3 is 3/5

Answer 58

Yeah :)

Good job
