lindsey bought 2 pizza and 3 orders of spaghetti from crazy pizza.if she spent at least $45,write an inequailty where x represents the cost of each pizza ,and y represents the cost of each order of spaghetti.graph the solution and label the axes.

\[C \ge 45\] since we want C to be equal to or more C=2x+3y so we have the inequality \[2x+3y \ge 45\] To graph this I would solve for y then and graph the form y=mx+b first then we will look at graphing the inequality part

chris97 just so you know i'm not sitting at my computer 24/7 okay?

  • anonymous
do you know how to graph it
myininaya
  • myininaya
yes use what I told you above to graph it
anonymous
  • anonymous
want to label the axes
myininaya
  • myininaya
I would let the x axis be the horizontal axis and the y-axis be the vertical axis
anonymous
  • anonymous
2,4,6,8,10,12,14,16,18,20 by both x and y
anonymous

what do you think the slope mind be
myininaya
  • myininaya
|dw:1328743835754:dw| so \[2x+3y \ge 45\] Solve this for y subtract 2x on both sides \[3y \ge -2x+45\] then divide both sides by 3 \[y \ge \frac{-2}{3} x+15\] So I told you to graph \[y=\frac{-2}{3}x+15 \] first then we will worry about the inequality part so this is in the form y=mx+b where m=slope and b=y-intercept so what do you think is m and what is b?

|dw:1328744149997:dw|and all number when it get to 20 both x and y axes but the graph on my paper say that the graph look like this
myininaya
  • myininaya
so anyways m=-2/3 and b=15 right?
anonymous
  • anonymous
yes
myininaya
  • myininaya
|dw:1328744403682:dw|
myininaya
  • myininaya
|dw:1328744423950:dw| i put a point on the y-axis since we know the y-intercept
anonymous
  • anonymous
how does it look then
myininaya
  • myininaya
now i'm going to go down 2 times and go right 3 times
myininaya
  • myininaya
|dw:1328744464739:dw|
myininaya
  • myininaya
now i'm going to connect the dots
myininaya
  • myininaya
|dw:1328744508700:dw|
myininaya
  • myininaya
the graph looks something like that
myininaya
  • myininaya
but now we have to come back to the inequality part
anonymous
  • anonymous
do i just keep going with the piont then
myininaya
  • myininaya
we have y>=-2x/3+15 we already took care of the equal part now we need to look at greater than part
anonymous
  • anonymous
by 2/3
myininaya
  • myininaya
> means we need to shade everything above the line the slope was -2/3 not 2/3
anonymous
  • anonymous
sorry
myininaya

ok i under stand now
