Question

1. which inequality matches the graph?
2n + 5 < 7 (this < sign has a line under it)
2n - 5 < 7
2n + 5 < 7
2n + 5 > 7 (this > sign has a line under it)

2. which inequality matches the graph?
6w + 6> 18
6w + 6> 18(this > sign has a line under it)
6w - 6> 18

Answer 7

alright
for 1st one we got this-

and the options are these-
\(2n + 5 \le 7\)
\(2n-5<7\)
\(2n+5<7\)
\(2n+5 \ge 7\)

1st thing to notice is-> \(n\) is nothing but the values the graph can obtain.
1st we analyze the graph
well in the graph all values starting from 1 and going to \(-\infty\) are included
so we can say that -> all values are less than or equal to 1.
so basically->
\(n \le 1\)


now we look at our options and try to simplify them so that we can obtain this form-> \(\color{blueviolet}{n \le 1}\)

alright so we start from option 1 and simplify it

\(2n +5 \le 7\)
\(2n+5-5 \le 7-5\)
\(2n \le 2\)
\(\large \frac{2n}{2} \le \frac{2}{2}\)
\(n \le 1\)

:) this is what we wanted so in question 1 option 1 is correct

the second problem is similar try to do that (:

Answer 20

i have one more question can you help me real quick with it

Answer 21

alright :)

Answer 22

An airline requires carry-on luggage to weigh at most 40 pounds. Your suitcase currently weighs 10 pounds. How many pounds p are available for you to fill your suitcase with other items?

p - 10 ≤ 40; p ≤ 50
40 - p < 10; p < 30*** [think it is this one]
p + 10 ≥ 40; p ≥ 30
10 + p ≤ 40; p ≤ 30

Answer 23

close this question open another

Answer 24

no i am not

Answer 25

it is in the code of conduct you can be reported for that

Answer 26

:) its alright
since you are new and don't know

Answer 27

omg seresly

Answer 28

not u imqwerty i was talking to gigiheart

Answer 29

sorry I did not know you were new

Answer 30

well if you ask many question on a single post it might happen that the post starts lagging due to so many comments there. So they recommend making new posts for new questions

anyways :) back to our problem

alright
so we can have 40 pounds at most

we already have 10 pounds
so if we wanna add \(p\) more pounds of luggage to our bag then-
so \(p\) can be 30 pounds at max
anyways the total weight of our luggage must be less than or equal to 40


so
\(p+10 \le 40\) ; \(p \le 30\)

Answer 31

thank you so much

Answer 32

np :)

Answer 33

wait they dont have that answer choice

Answer 34

p + 10 ≥ 40; p ≥ 30 there is this way

Answer 35

see the last one :)

Answer 36

you but the arrows the other way

Answer 37

i mean last option

Answer 38

oh ok

Answer 39
