Question

y<= –x + 7
y < 3x + 11

Answer 1

How do I solve?

Answer 2

solve for a variable and put it into the other

Answer 3

as a system? or independently?

Answer 4

As a system

Answer 5

what imasofty said...

Answer 6

wait, is one <= and the other just < ?
or is that a typo?

Answer 7

one is less then or equal to and the second one is just less than

Answer 8

hm....
that throws me so I'm not sure, sorry.
I just did this:
solve
y<= –x + 7
for x and plug it into the other inequality, which gave me
y<8
but I think that may wrong because it doesn't take into account the <=
sorry... I won't tell you I know if I'm not sure.

Answer 9

yea theres somthing funny you gatta do...its from pre calc i think

Answer 10

Im in alg II not precalc!

Answer 11

moneybird is on the case, he should know what to do...

Answer 12

thank you moneybird

Answer 13

thank you everyone who is trying to help me!

Answer 14

what i would have done is used a graph to solve it and got the answer on a graph paper, would have much simpler

Answer 15

how do i graph it? y=mx+b?

Answer 16

you can graph it by finding the intercepts on the x and y axis

Answer 17

turning test will help you graph it he knows that :D lol turning you should have known this man u r better than me :D i need to go tc Sweden :D

Answer 18

lol yes you do@ Akshay Budhkar... but im in USA now

Answer 19

No, I think you and I are pretty close @akshay
anyway, yes you can graph the individual lines like y=mx+b
then use the inequality properties to find the solution area.
I don't want to go through that step-by-step, but I'll see if I can get wolfram's answer:

Answer 20

ok, here's what I got
all I see to do is to find the intersection of the two lines:
3x + 11= –x + 7
which is (-1,8)
the intercepts of y=-x+7 are x=7 y=7 (that doesn't seem to matter here though)
the x-intercept for y=3x+11 is -11/3
now all I can think to myself is that the graph looks something like this:...
