Answer 1

@radar

Answer 2

please help me

Answer 3

what is the first (-2,-14) ?

Answer 4

like plugin in -2 for x

Answer 5

It is not labeled as a choice? or is it supposed to be choice A ?

Answer 6

yes,

Answer 7

No I mean sorry

Answer 8

can you edit the question? otherwise it will be confusing

Answer 9

ok

Answer 10

Which ordered pairs are solutions to the inequality y – 4x ≤ –6?
Choose all answers that are correct.


A.(–2, –14)
B.(–1, –9)
C.(0, –5)
D.(3, 5)
E.(1,3)

There all answer choices, pick all that are correct

Answer 11

y-4x are "instructions" that says
multiply the first number ( the x number in a pair) by -4
then add it to the 2nd number (the y number in a pair)
can you do that for the pair (-2,-14) ?

Answer 12

ok, you don't have use answer choices. May i have an example

Answer 13

for (-2,-14)

multiply the first number by -4: -2*-4
then add the 2nd number: -14
can you do that ?

Answer 14

ok

Answer 15

16--14=30

Answer 16

first do -2*-4

Answer 17

8

Answer 18

now add -14

Answer 19

-6

Answer 20

yes. now we have
\[ y - 4x \le -6 \\ -6 \le -6\]
the little _ under the \( \lt\) means equal.
is -6 = -6 ?

yes.
so choice A works.

Answer 21

ok, now do the same thing for all of them

Answer 22

now try
(–1, –9)
in
-4x+y (this means the same as y + -4x or y-4x)

and you do
-4* -1
add -9

Answer 23

4+9=13

Answer 24

the 2nd number in (-1,-9) is not +9. it is -9

Answer 25

5

Answer 26

4+ -9 = what ?

Answer 27

-5

Answer 28

when you add numbers with different signs, subtract them (ignoring the sign)
and make the answer the same sign as the "bigger" number.
yes we get -5

Answer 29

now
\[ -5 \le -6\]
it is clearly not equal.
notice the "big" end of the \( \le\) is next to -6. that means we want -6 to be bigger than the other side

is -6 bigger than -5 ?

Answer 30

no

Answer 31

ok, -5 is bigger than -6 and we want numbers smaller than -6
so cross off choice B.

so far , only A works.

Answer 32

ok

Answer 33

C. (0, –5)

-4 x + y

do -4 * 0
then add -5

Answer 34

-5

Answer 35

and we just did \( -5 \le -6\). Not true. cross off choice C

Answer 36

ok

Answer 37

can you try
D. (3, 5)
and show your steps.

Answer 38

ok

Answer 39

D. (3,5)
-4x + y
-4 * 3=-12
add 5
=-7

Answer 40

ok, and is \(-7 \le -6\) true or false?

Answer 41

yes

Answer 42

true

Answer 43

ok, so choice A and choice D

one more to go
E. (3, 5)

Answer 44

I thought we just did 3,5

Answer 45

wait, E is (1,3)

Answer 46

E. (1,3)
-4x+y
-4*1=-4
add 3, -4+3=-1
-1 Is bigger than -6 so the equation is false

Answer 47

yes. now double check your question, that choice D is (3,5) and E is (1,3)
up top you have it the other way round.

Answer 48

It is, Thanks so much, You've been a great help. Could you check another one of my answer. I'll post again

Answer 49

ok
