Question

HELP ME!!

Answer 1

with what? :)

Answer 2

It says for me to graph the solution set of the inequalitiles:
\[x+2y \ge 36 and 3x+4y \ge 84\]

Answer 3

how do i solve this?

Answer 4

can you draw first x+2y ?

Answer 5

so i don't really have to do any work?

Answer 6

what i mean is i don't have to show any work just graph it? how do i do that?

Answer 7

x + 2y >36
3x+4y>84
Multiply the first by -2
-2(x+2y>36)
-2x-4y>-72
Add 3x+4y>84
-2x + 3x - 4y +4y > -72 + 84
Combine like terms
x>12 where > is greater or equal to
Substitute x
12 + 2y > 36
2y >24
y>12 wher > is greater or equal to

Answer 8

i think you left out the equal sign in both the problems at the top.

Answer 9

x+2y>=36 and 3x+4y>=84
2y>=36-x 4y>=84-3x
y>=(36-x)/2 y>=(84-3x)/4
y>=18- x/2 and y>=21- (3/4)/4

Answer 10

Just make it clear:
x+2y ≥36
-> y ≥ (-x/2 )+ 18

3x+4y ≥ 84
-> y ≥ (-3x/4 ) + 21

Answer 11

Hint: intersection point ( 12, 12), intercept points ( 0, 18) and ( 0, 21)

Answer 12

y>=18- x/2 and y>=21- (3/4)/4
when x=0 when x=0,y>=21
y>=18
also when
y=0, x>-36 and when y=0,x>=84/3=28

Answer 13

@acegirl Questions?

Answer 14

ooopps sorry that is
y=0, x>=36

Answer 15

@Chlorophyll do i shad above the line or below the line?

Answer 16

okay thanks. also am i suppose to have 1 line or 2 lines? im just lost, sorry.

Answer 17

Yep, just follow @mark_o.'s instruction :)

Answer 18

shade above the line..on one line

Answer 19

2 regions generate from 2 inequalities!

Answer 20

Then the result is the overlap of both regions!

Answer 21

ok thanks i got it. sorry for all the trouble.

Answer 22

:)
