Answer 3

You have to fix this
" less than or greater to"
things are not both less than and bigger than a number
(example, you can't be both under 5ft tall and over 5 ft tall. It is one or the other)
maybe you mean less than or equal ? or just less than ?
or greater than or equal (written \( \geq \) ) or "greater than" written >

Answer 4

Equal to*

Answer 5

Yes less than or equal to

Answer 6

<= or \( \leq \)

Answer 7

second choice ≤

Answer 8

≤

Answer 9

refresh the page if u just see question marks.

Answer 10

oh, I meant they mean the same thing. <= is how to type it if you can't type the fancy way.

anyway, the system is :
y \( \leq \) x - 5
y \( \leq \) -x - 4

Answer 11

Yes thats the system and the 4 answer choices are listed below.

Answer 12

The easiest way is test the choices. Because we want y to be small, I would first test the choices with the smallest y value... hopefully that is the right answer.

Answer 13

C then?

Answer 14

if y were temperature, is 1 degree above zero colder than -10 (10 below ) ?

Answer 15

No.

Answer 16

phi could come to my Queation please

Answer 17

@,nmfrqew You dont just invade someones post to ask that.

Answer 18

in other words, -10 is the smallest y

but if you did test C we would use x=10
in the first equation
y <= x - 5
y <= 10-5 ?
y <= 5
y is 1 . it worked in the first relation. Now the 2nd:


y <= -x - 4
replace x with 10
y <= -10 - 4
y <= -14

y is 1 for choice C (remember we are checking (10,1) )
is 1 <= -14. ?

Answer 19

no

Answer 20

so I would test choice D. chances are it works.

Answer 21

omg

Answer 22
