Answer: g = 40f
Step-by-step explanation:
Since one water filter will clean 40 gallons of water, the equation that can be used to find g, the total number of gallons that will be cleaned by any number of filters f will be gotten by multiplying f by 40. This will be:
g = f × 40
g = 40f
For example, the gallons of water that 4 water filters will clean will be:
= 40f
= 40 × 4
= 160 gallons
Answer:
x=126/13
Step-by-step explanation:
We know that
the quadratic function in vertex form is--------------> y=a*(x-h)²+k
we have
f(x)=x²<span>+14x+40
y=</span>x²+14x+40
We can convert to vertex form by completing the
square on the right hand side
y-40=x²+14x
y-40-49=x²+14x-49------> subtract 49 on BOTH sides to
preserve the equality
y-40=(x²+14x+49)-49
y=(x²+14x+49)-49+40---------> y=(x+7)²-9
the answer is
the quadratic function in vertex form-----------> y=(x+7)²-9
<span>the vertex is the point (-7,-9)

Your answer is 9. Hope this helps, if not, please comment below!
From the looks of it, each one is multiplied by -2, so it will be
-4,8,-16,32,-64,128,-256
