V = s/t

now, t is equal for both cases so we write these 2 equations:
440/(Vp+Vw) = t

and 

340/(Vp-Vw) = t
Now again, since t is equal for both cases we can make these 2 equations equal to eachother.
440/(Vp+25) = 340/(Vp-25)
(Vp - 25)*44=34*(Vp+25)
44Vp - 1100 = 34Vp + 850
10Vp = 1950
Vp = 195

Answer is 195mph

The functions f(x) and g(x) are described below: f(x) = 7x + 9 g(x) = 7x −4 The graph of g(x) is obtained by shifting down the g
Slav-nsk [51]
Correct Answer:
Option A

Solution:

f(x) = 7x + 9
g(x) = 7x - 4

We can re-write g(x) as:

g(x) = 7x + 9 - 13

Since 7x+9 is equal to f(x), we can write:

g(x) = f(x) - 13

This relation shows that g(x) is obtained by shifting f(x) 13 units vertically down. So the correct answer is option A.

City records showed that 0.8% of new homes had no
storchak [24]

Answer:

The decimal would be 0.008.

If you wanted a fraction in simplest form, it would be 1/125.

Step-by-step explanation:

0.8% divided by 100 (move the decimal in the percent two places to the left) = 0.008

0.008 as a fraction is 8/1000, and then you divide both numbers by their GCF of 8, which will give you a fraction in simplest form of 1/125.

I hope this helps!
