Note: The graphical answer to your inequality DOES NOT INCLUDE any point on the black solid curve. On your work, you should draw the solid curve shown as a dashed curve.

- anonymous

Yeah

- anonymous

Curve meaning line?

- anonymous

yea sorry :)

- anonymous

So it would be a dashed line with shading on the side that does not include the origin?

- anonymous

im sorry the graph i gave you was wrong...the shading is on the opposite side
the graph of the inequality -3x-y>-6 is a dashed line with shading on its left

Solve the inequality 2x + 8 < 5x - 4

- jim_thompson5910

Start by subtracting 5x from both sides

- anonymous

Is the answer x>4?

- jim_thompson5910

you got it

- anonymous

I'm just going to throw questions at you one after another, is that cool with you?

- jim_thompson5910

sure

- anonymous

Which of the following ordered pairs is not a solution to the inequality y > -3x + 5?
(0, 6)
(2, 0)
(-1, 9)
(1, -1)

- jim_thompson5910

tell me what you get or if you need help

- anonymous

Could you help?

- anonymous

Wait, is it (0,6)?

- jim_thompson5910

alright

- jim_thompson5910

y > -3x + 5
6 > -3(0) + 5 .. Plug in (0,6)
6 > 0 + 5
6 > 5
which is true
so it's a solution
Do the same for the others

- jim_thompson5910

There are others that could be the solution (you don't know until you can verify or rule them out)

- anonymous

Wait never mind lol (1,-1)?

- jim_thompson5910

you got it, (1, -1) is the answer

Connie needs to burn at least 500 calories at the gym today. She can burn 20 calories per minute on the treadmill (t) and 10 calories per minute on the elliptical trainer (e). Which inequality below can be used to find the possible combinations of time she could spend on each machine and still meet her goal of burning at least 500 calories?
20t - 10e 500
20t + 10e 500
20t - 10e 500
20t + 10e 500

- anonymous

Oh, sorry, I forgot the signs, the first one is greater than or equal to, the second is less than or equal to, the third is greater than or equal to, the fourth is less than or equal to.

- anonymous

sorry, another mistake lol, it was the 1st and last are greater than or equal to, the middle two and less than or equal to.

- jim_thompson5910

which one do you think it is
