12 yards = 12 x 3 = 36 feet
1 foot = 1 banner.
36 feet = 36 banners.

Answer: 36 banners

The last image is the graph of 
In fact, it is an increasing exponential function, and it passes through the points
, which reflects the fact that
and
, which reflects the fact that
.
Now,
is a child of the parent function we just described. Precisely, it is the result of the transformation 
In general, every time you perform a transformation like
, you translate the graph horizontall, k units to the left if k is positive, and k units to the right if k in negative.
Since in this case
, we have a horizontal translation of 4 units to the right.
So, the correct option is the third one, because:
- The first graph is the parent function translated 4 units to the left
- The second graph is the parent function translated 4 units down
- The third graph is the parent function translated 4 units to the right
- The fourth graph is the parent function
The exact form is x= -3/14
You gather the like terms together.
if you have -3y +2x +6w -4 + 3y -5x +2w
you put the like terms together
so for the term y:
you have -3y +3y = 0
for x:
2x - 5x = -2x
for w:
6w + 2w = +8w
and you also had -4. if you put them together you get
0 -2x +8w -4
which is
-2x +8w -4
hope this helps
