Question

Algebra 1 Questions

Answer 1

Volume = Length * width * height
V = L * W * H
V = 5 * 6 * 9
V = 270 in^3

270/.625 = 432 bags

I guess I did that right...not the best at geometry

Answer 2

oops....V = 270 ft^3

Answer 3

too bad it is not multiply choice...that would give me something to go by to see if I did it correctly

Answer 4

I got 432 too. I think you're right. ^-^ Could you help me with a few more?

Answer 5

wait..the more I look at the problem...it might not be right. Because the length is in feet, but the height and width are in inches....not too sure about this one

Answer 6

I can continue to help you....hopefully you do not have geometry problems....I am no good at geometry

Answer 7

Okay. :D

Answer 8

if 1 miles is 1.6 km, then 40 miles = (1.6 * 40) = 64 km

1/64 = x/20 (1 gal to 64 km = x gal to 20 km)
cross multiply
64x = 20
x = 20/64
x = .3125 rounds to .3

Answer 9

You're the best. You really are. c:

Answer 10

not the best because I do not know this one...sorry

Answer 11

Oh, that's fine. :)

Answer 12

x + 3x + 2 + 1/2x = 29 -- combine like terms
4.5x + 2 = 29 -- subtract 2 from both sides
4.5x = 27 -- divide by 4.5
x = 27/4.5
x = 6 (this is the weight of the fertilizer.

the weight of compost is half the weight of fertilizer...
C = 1/2f and we already know that f = 6

so, C = 1/2(6) = 6/2 = 3 kg

Answer 13

let me rephrase this....x = fertilizer
C = 1/2x
C = 1/2(6) = 3 kg

Answer 14

Ah, I see.

Answer 15

100 + 38x = 328 -- subtract 100 from both sides
38x = 328 - 100
38x = 228 -- divide by 38
x = 228/38
x = 6

I am gonna say B....I was kinda stuck between A and B, but your question says Fiona wants to join for a minimum of 1 month, so I pick B

Answer 16

She can't join for more then 6 months or she will go over her allotted budget.

Answer 17

Quite true! ^-^

Answer 18

2 | 2x - 2 | + 4 = 20 -- subtract 4 from each side
2 | 2x - 2 | = 16 -- divide both sides by 2
| 2x - 2 | = 16/2
| 2x - 2 | = 8

2x - 2 = 8
2x = 8 + 2
2x = 10
x = 5

-(2x - 2) = 8
-2x + 2 = 8
-2x = 8 - 2
-2x = 6
x = -3

x = 5 and x = -3

Answer 19

3x - 2 > 5x + 10 -- add 2 to both sides
3x > 5x + 10 + 2 -- subtract 5x from both sides
3x - 5x > 10 + 2 -- combine like terms
-2x > 12 -- divide by -2 and change the sign
x < 12/-2
x < - 6

Answer 20

please do me a favor and close this question...I really do not want to get booted off for giving answers

Answer 21

Yes ma'am.

Answer 22

| 3x - 6 | > 3

3x - 6 > 3 -- add 6 to both sides
3x > 3 + 6
3x > 9 -- divide by 3
x > 3

3x - 6 < -3 -- add 6 to both sides
3x < -3 + 6
3x < 3 -- divide by 3
x < 1

so we have x is less then 1 and greater then 3...also there will be open circles because there is no equal sign...so it is graph A

Answer 23

:)

Answer 24

-np - 4 <= 2(c - 3) -- distribute through the parenthesis
-np - 4 <= 2c - 6 -- add 4 to both sides
-np <= 2c - 6 + 4
-np <= 2c - 2 -- now divide by p
-n <= (2c - 2)/p

I am getting stuck here....we do not want a -n, but if we multiply by -1 and change the sign, we get : n >= (-2c + 2)/p....not an answer choice

Answer 25

Hm. That's fine, we can just do a different one. I'll figure it out. ^-^

Answer 26

same question dude

Answer 27

be right back in a minute

Answer 28

Okay. And, I fail.

Answer 29

I found the answer to the question I was stuck on...your last question before this one...answer is C

Answer 30

| 2x - 6 | < 4

-4 < 2x - 6 < 4 -- add 6
6 - 4 < 2x < 4 + 6
2 < 2x < 10 -- divide by 2
2/2 < x < 10/2
1 < x < 5

so we have x is greater then 1 and less then 5....graph D

Answer 31

Sorry, I disappeared on you.

Answer 32

no need to be sorry...I kinda left first....I posted your question, the one I was confused about....got the answer for you..it was C.

Answer 33

I saw. Thanks so much! You think you can do like 5 more?

Answer 34

possibly...what ya got

Answer 35

I won't leave this time..lol

Answer 36

Lol, okay. ^-^

Answer 37

oh....I do not know recursive functions...sorry

Answer 38

Oh, that's fine. c:

Answer 39

(-2,3) -- x1 = -2 and y1 = 3
(2,7) -- x2 = 2 and y2 = 7
slope = (y2 - y10 / (x2 - x1)
slope = (7 - 3) / (2 - (-2)
slope = 4/(2 + 2)
slope = 4/4 = 1

(2,7) -- x = 2 and y = 7
slope(m) = 1
y = mx + b
7 = 1(2) + b
7 = 2 + b
7 - 2 = b
5 = b

y = x + 5 -- subtract x
-x + y = 5 -- multiply by -1 to make x positive
x - y = -5 ===> your equation

Answer 40

c:

Answer 41

Sorry that one took so long to post, had to do the choices separate from the question.

Answer 42

I wanna say D.....was kinda stuck between D and A...but A just drops off at the end, when she is supposed to stop. A just stays the same. What do you think...A or D ??

Answer 43

oops... D just drops off at the end and A just stays the same

Answer 44

lol....A drops off and D stays the same...these are messing with my brain

Answer 45

Lol. Oh, and I think that D doesn't drop off the end, but ends right at (50, 40)

Answer 46

A, sorry. It's messing with my head too, lol.

Answer 47

Okay, okay, I think that A ends at (50, 0) is what I meant. Very confusing.

Answer 48

Do you think it is D or A....because I am leaning towards D, but not 100% sure

Answer 49

This is your grade so you have to make the final decision....no pressure...lol

Answer 50

Lol, okay. I'm going with D.

Answer 51

I think it is B. Its either B or D. The reason I am guessing B is because integers can't be irrational. and I do not think irrational numbers would work

Answer 52

how many more you got because I have to go somewhere soon ?

Answer 53

y = x + 5
slope is 1

parallel line will have same slope.
(-2,-1) -- x = -2 and y = -1
y = mx + b
-1 = 1(-2) + b
-1 = -2 + b
-1 + 2 = b
1 = b
parallel line is : y = x + 1

perpendicular line will have negative reciprocal slope, so slope is -1
(-2,-1) -- x = -2 and y = -1
y = mx + b
-1 = -1(-2) + b
-1 = 2 + b
-1 - 2 = b
-3 = b
perpendicular line is : y = -x - 3

Answer 54

Thanks. ^-^

Answer 55

you got anymore or is that it ?

Answer 56

Oh, wait, one more.

Answer 57

thats gonna be graph A because it only crosses the y axis at 4....it never crosses the x axis. It is a horizontal line. y = is a horizontal line.....x = is a vertical line.

Answer 58

I really got to go now...I hope I helped some....although I am sorry I could not help on all of them. I will be back on later. See ya :)

Answer 59

See ya!

Answer 60
