2x < -12 or x + 3 greater than or equal to 12

A number line with an open circle on -6, shading to the left, and a closed circle on 9, shading to the right.

A number line with a closed circle on -6, shading to the left, and an open circle on 9, shading to the right.

A number line with an open circle on -6, a closed circle on 9, and shading in between.

A number line with a closed circle on -6, an open circle on 9, and shading in between

Answer 1

what do you get when you solve 2x < -12 for x?

Answer 2

?

Answer 3

how would you solve 2x < -12 for x

Answer 4

I don't know

Answer 5

how would you undo the multiplication of 2

Answer 6

divion

Answer 7

division by what

Answer 8

2

Answer 9

so divide both sides by 2

Answer 10

2x < -12

x < ???

Answer 11

-6

Answer 12

2x < -12

x < -6

Answer 13

good

Answer 14

how would you graph that?

Answer 15

The first one

Answer 16

correct

Answer 17

Solve for x: -3(x - 3) = 21

x = -10

x = 10

x = -4

x = 4

Answer 18

you could take the traditional route and directly solve for x

or you could plug in each answer choice and see which one produces a true equation

Answer 19

the last one

Answer 20

Good job dude!

Answer 21

oh wait you forgot something

Answer 22

look again

Answer 23

x=-4

Answer 24

right!

Answer 25

Greg combined different weights of fertilizer, soil, and compost to make 29 kilograms (kg) of potting soil for some plants. The weight of fertilizer was x kg. The weight of soil was 2 kg more than three times the weight of fertilizer, and the weight of compost was half the weight of fertilizer. This is represented in the equation below.
x + (3x + 2) + one half x = 29
What was the difference in the weights of soil and compost Greg combined?

3 kg

6 kg

14 kg

17 kg

Answer 26

I've got this one and 7 more to do and then I'm done

Answer 27

you got the answer?

Answer 28

Its the 3rd one

Answer 29

Good stuff!

Answer 30

(-3, 2)

(0, -3)

(3, 5)

(2, 8)

Answer 31

the second one

Answer 32

good

Answer 33

am I getting them right

Answer 34

yea

Answer 35

Evaluate the following expression using the values given.
Find 4x - 6y if x = -2, y = 3

Answer 36

-26

26

-10

10

Answer 37

the first one

Answer 38

yeah

Answer 39

is it the second one

Answer 40

no we have
-8-18=-26

Answer 41

ok

Answer 42

What is the equation of the line that passes through the points (-2, 1) and (1, 10)?

3x - y = -7

3x - y = -5

3x - y = 5

x + 3y = -5

Answer 43

Slope = y1-y2/x1-x2

Answer 44

so its the last one

Answer 45

nope

Answer 46

Third one

Answer 47

Nope. we have a slope of 3 and we know what y=mx+b is right?

Answer 48

second one

Answer 49

no hold on lets work through this. y=mx+b where m is slope and b where it crosses the y axis.

So we have y=3x+b, but we need to know what b is, but we know it has to cross both of those points, so if we take one of those points and plug the x and y values into the equation and solve for b

like this

10=3(1)+b --> 10=3+b ---> b=7

so now we have y=3x+b, which can be rearranged to 3x-y=-7

Answer 50

Compare and Contrast: Below are two equations. Solve each equation and compare the two solutions. Choose the statement that is true about each solution.




Equation #1

Equation #2


3x - 18 = 2x - 20

10 - 2x = 4x + 34


The solution to equation #1 is smaller than the solution to equation #2.

The solution to equation #1 is larger than the solution to equation #2.

The solution to equation #1 is the opposite of the solution to equation #2.

None of the statements above describe solutions to equations shown.

Answer 51

Put x's on one side and constants on the other.

equation 1: 3x-18=2x-20 ---> 3x=2x-2 ---> x=-2

equation 2: 10-2x=4x+34 ---> -24 -2x =4x---> -24=6x ---> x=-4

Answer 52

-2>-4

Answer 53

second one

Answer 54

yes

Answer 55

Evaluate: -8 + 4

-12

-4

4

-32

Answer 56

4-8=-4

Answer 57

Simplify quantity 3 times x plus 9 all over 3

3x + 3

x + 3

x + 9

x

Answer 58

x+3

Answer 59

\[\frac{ 3x+9 }{ 3}\]

the 3x can be divided 3 and the 9

answer\[x+3\]

Answer 60

forget that one

Answer 61

Are you sure? I can do it.

Answer 62

Assume a 150 pound person burns 120 calories after 2 hours of sleep and 240 calories after 4 hours of sleep.
Part 1 (2 points): Use calories as the y-coordinate and hours as the x-coordinate. After writing two ordered pairs, find the slope. What does the slope represent in terms of the information provided?

Part 2 (2 points): Write an equation, in slope intercept form, to represent this data.

Part 3 (2 points): How many calories will this person burn after 8 hours of sleep? Using complete sentences, explain how the equation, slope, or graph can help to predict calories burned.#

Answer 63

(2,240), and (1,120) slope = \[\frac{ y1-y2 }{ x1-x2 } = \frac{ 240-120 }{ 4-2 } = \frac{ 120 }{ 2 } = 60\]

Answer 64

y=60x+0

Answer 65

8*60=480

Answer 66

is that part 1 to 3

Answer 67

yup

Answer 68

how do I write the part 1

Answer 69

slope=60

Answer 70

and part just put y=60x+0 and part just put 8*60=480

Answer 71

yup

Answer 72

Aldora decides to join a gym for a minimum of one month to train for a triathlon. The gym charges a joining fee of $100 and a monthly fee of $36. If x represents the number of months that Aldora is a member of the gym, the equation below can be used to determine C, her total membership fee for that duration of time.

100 + 36x = C

Aldora has allocated a maximum of $352 to spend on her gym membership. Which number line shows the possible number of months that Aldora can be a member of the gym?

Answer 73

u said u could do it

Answer 74

yup

Answer 75
