>= means greater than or equal to
<= means less than or equal to

---------------------------------------------

Part A

The graph of y >= -3x+3 will have a solid boundary line and the shading will be above the boundary line.

The boundary line y = -3x+3 has a negative slope so it moves down as you read it from left to right. It goes through the points (0,3) and (1,0)

--------------

The graph of y < (3/2)x - 6 will have a dashed or dotted boundary line. The shading is below the boundary.

The graph y = (3/2)x-6 goes through the two points (0,-6) and (2,-3)

--------------

If you graph both y >= -3x+3 and y < (3/2)x - 6 together, you get what you see in the attached image. This solution shaded region is the result of the overlapping prior shaded regions. 

---------------------------------------------

Part B

Plug (x,y) = (-6,3) into each inequality to see if we get a true inequality or not

For the first inequality we have
y >= -3x+3
3 >= -3*(-6)+3
3 >= 18+3
3 >= 21
which is false. The value 3 is not larger or equal to 21. So right off the bat we know that (-6,3) is NOT a solution. It is NOT in the solution region.

Let's check the other inequality just for the sake of completeness
y < (3/2)x - 6
3 < (3/2)*(-6) - 6
3 < -9 - 6
3 < -15
this is also false. The value -15 is smaller than 3, since it is to the left of 3

We're given more evidence that (-6,3) is NOT in the solution area. It is outside of both shaded areas.

What is a​ placebo and why is it important?
Ksju [112]

Answer:

A placebo is a fake put into place in order to make a user believe something is happening when it is not.

Step-by-step explanation:

A placebo is a fake put into place in order to make a user believe something is happening when it is not. This is used often in medicine, where a doctor may tell a patient they are receiving treatment for some condition, but in fact they are getting nothing. Often times this can actually make a change for the patient due to simply believing they are getting treatment. The placebo effect is also used in Statistics, with 2 groups, one getting the treatment, and one simply receiving a placebo. This is helpful because it shows the effect of treatment or medication more accurately.
