HELPP IN THE PICTURE

Mathematics
1 answer:
Sauron [17]3 years ago
8 0

Answer:

Given in the question an expression,

y = 3x/(8+x)

Step1

interchange the variables

x = 3y/(8+y)

Step 2

x(8+y) = 3y

Step 3

8x + xy = 3y

Step 4

8x = 3y - xy

Step 5

8x = y(3 - x)

Step 6

8x = y(3 - x)

Step 7

y = 8x/(3-x)

Step 8

y = f(x^-1) = 8x/(3-x)

So the inverse of  f(x)= 3x/(8+x) is f(x^-1) = 8x/(3-x)

nt is the number of payment times you expected (4 years, twice a year = 8 times)

Step-by-step explanation:

Given that:

Speed of microwave (v) = 2,000,000 m/s

Wavelength, λ = 0.0345 m

Frequency :?

Using the relation :

v = fλ

f = v / λ

f = 2,000,000 / 0.0345

f = 57971014.49 Hz

138 times .40-move the decimal over 2 times

that is 55.2 so 40 percent of 138 is 55.2 so add that on to 138 to get 192 students at the school. There you go  :)
