Question

An inequality is shown below:

-np - 5 ≤ 4(c - 2)

Which of the following solves for n?

n ≥ - the quantity 4 times c minus 3 all over p
n ≥ - the quantity 4 times c minus 13 all over p
n ≤ - the quantity 4 times c minus 3 all over p
n ≤ - the quantity 4 times c minus 13 all over p

Answer 1

@welshfella

Answer 2

first of all distribute parentheses by outside term

Answer 3

so -np-5<=4x-8

Answer 4

-np - 5 ≤ 4(c - 2)

np+5

Answer 5

alright yes that's right
you have to isolate n
so move -5 to the right side
and remember when you MULTIPLY or DIVIDE by negative number then you should flip the inequality sign

so -np-5<=4x-8

4c*

Answer 7

np +5 >=- 4(c - 2)

np >= -4c +8-5

np> = -4c+3

Answer 8

ok

Answer 9

why do i do after?

Answer 10

divide by p

Answer 11

np/p=-4c+3/p
n>=4c-3/p

Answer 12

-np - 5 ≤ 4(c - 2)
-np - 5 ≤ 4c - 8
adding +5 for both sides
-np=<4c-8+5
-np=< 4c-3
multiply by (-1)
np >=-4c+3

Answer 13

based on that a is the answer?

Answer 14

based on what ?
\[\rm n \ge \frac{ -4c \color{reD}{+}3 }{ p }\]
n ≥ - the quantity 4 times c **minus** 3 all over p

Answer 15

or you can write it as
\[\rm n \ge \frac{ 3 -4c }{ p }\]
but still 3 is positive
take a screenshot

Answer 16

well none of this options have that so a right?

Answer 17

a is incorrect
but bec none of options are right so yeah a.......:/

Answer 18

n ≥ - the quantity 4 times c minus 3 all over p

\[\rm n \ge \frac{ -4c \color{reD}{-}3 }{ p }\]

\[\rm n \ge \frac{ \color{reD}{-} (4c \color{reD}{+}3) }{ p }\]
negative sign is common so take it out

Answer 19

if we do backwards then that^^ makes sense

Answer 20

ok just to claify because i do not want to get it wrong a is correct

Answer 21

@nn

Answer 22

i guess YES

Answer 23

ok may you help w. another ?

Answer 24

i'll try

Answer 25

ok

Answer 26

Which equation is not equivalent to the formula e = mc?

m equals e over c
c equals e over m
e = cm
m equals c over e

Answer 27

i think its d @Nnesha

Answer 28

how ?
can you explain a littlebit ?

Answer 29

:-)

Answer 30

well sure i solve for m and c idk about the e=cm but that leaves us with m=c/e

Answer 31

solve for e m =c/e

Answer 32

yes that's right m = c/e
equal to em =c which is not equivalent to e =mc

Answer 33

wait so d is right??

Answer 34

it is not equally to e=mc because what u said before confused me :D

Answer 35

ye d is right

Answer 36

equation is e = mc m TIMES c
and D is m = c/e which is em = c
solve for e you will get e = m/c m OVER c
