<span>so your equation would be 2x-3=-1 then your answer would be -1

Mult. f(x) = x^4 by 2 will stretch the graph vertically by a factor of 2.
Thus, eliminate (a) and (b).
Mult. x by (1/4) will stretch the graph horiz. by a factor of 4. Thus, (c) is the correct answer.
Answer:

Answer:
The answer is
D. V= 19200- 12t
Step-by-step explanation:
in this problem, we already know that the pool contains 19200 gallons of water
and the pool is draining at 12 gallons per minutes, hence the volume is decreasing at that rate
Therefore for t minutes it will decrease by 12t
hence the volume after t minutes will be
V= 19200-12t
we have that
−4+8−16+32−.....
a1=-2*(-2)-----> -4
a2=-4*(-2)-----> +8
a3=+8*(-2)-----> -16
a4=-16*(-2)----> +32
a5=+32*(-2)----> -64
a6=-64*(-2)-----> +128
a7=+128*(-2)-----> -256
The sum of the first 7 terms of the series is
<span>[a1+a2+a3+a4+a5+a6+a7]-----> [-4+8-16+32-64+128-256]------->
-172</span>
<span>
the answer is -172</span>
