Answer: all real numbers

Step-by-step explanation:

The domain is how many x values are possible, but there is no limit to that, it is infinite. So the domain is all real numbers.

Answer:

All real numbers

Step-by-step explanation:

The domain is where the graph touches all of the x-coordinates. This parabola touches all x-coordinates from -infinity to +infinity (all real numbers) because it continues outward forever.

Well I don't know !
Let's check out the choices:

A).    3a - 4b = 21,  a=0, b=7

         3(0) - 4(7) = 21

             0  -  28  = 21    Nope.  That's not true.


B).  3a - 4b = 21,  a=-3,  b=2

     3(-3) - 4(-2) = 21

       -9    +  8  = 21

             -1    = 21      Nope.  That's not right.


C).  3a - 4b = 21,    a=-2,  b=-3

      3(-2) - 4(-3) = 21

         -6  + 12  = 21

                 6  =  21          Nope.  That's not it.

Only one choice left.
This one had better be it:

D).  3a - 4b = 21,    a=7,  b=0

       3(7) - 4(0) = 21

         21 -  0    = 21

               21  =  21            Yay !   That's it !

(Teaser) An angle that measures 6° is drawn on a piece of paper. You are looking at the angle through a×6 magnifying glass, whic
cluponka [151]

Answer:

No change in angle it will remain 6 degrees only.

Step-by-step explanation:

measurement of angle on paper = 6 degrees

power of magnifying glass = a*6

it means that the glass enlarges any thing seen through it by 6 times.

so if you are watching 1 cm object, it will be 1*6 times larger (i.e 6 cm) when seen through the magnifying glass.

It is to be noted that glass changes the size of the object, it does not change the shape of object. Th object will remain similar to the older one.

________________________________________________

Now given that

measurement of angle on paper = 6 degrees

This is a tricky question, here change of size of object is not being asked .

Since angle determines the shape of object , so angle will remain similar to as that on paper only size will get enlarged.

Hence, the measure of angle will remain same i.e 6 six degrees only. It will not change.

only thing will be that the shape of angle will appear larger but there will be no impact on angle.
