Question

when you graph y+3<7
y=4
<-----) or <-----] how do i know which to use

Answer 1

ohhh.....

do you see what an equals sign looks like? (=)

Answer 2

if you put a bar between it it looks kinda like [ or ] right?

"[" means equal to

Answer 3

which just leaves ( to mean not equal to

Answer 4

y >= 4; [4,inf)

x<3 ; (-inf,3)

z <= -2 and z<7; (-inf,-2] U (7,inf)

Answer 5

ok so then i would use <-----)

Answer 6

are you trying to graph the solutions to the 2 equations posted?

Answer 7

its just one equation
solve y+3<7
which is 4
so the solution is y/y<4

Answer 8

i see it:

y+3 < 7 the answer then is: (-inf,4)

Answer 9

does that make sense?

Answer 10

not exactly

Answer 11

4<x<14
graph & write in interval notation
