Equivalent fractions for 9/11, 15/17, and 2/3 using the least common denominator.

1 answer:

8 0

The (small) challenge here is to determine what the LCD is. Since 11, 17 and 3 are all prime, we find the LCD by multiplying them together: 561.

Then 9/11= 459/561; 15/17 = 495/561; and 2/3 = 375/561.

Find the inverse of the function f f (x ) equals 9 x + 7

MrMuchimi

Note: Your question seems a little bit ambiguous. So, I am assuming the given function f(x)=9x+7.

Thus, I am solving based on it. It would still clear your concept.

Answer:

The inverse of f(x)=9x+7

$\frac{x-7}{9}$

Step-by-step explanation:

Given the function

$f(x)=9 x + 7$

A function g is the inverse of function f if for y=f(x), x=g(y)

Replace x with y

$x=9y+7$

solve for y

$9y=x-7$

$y=\:\frac{x-7}{9}$

Therefore,

The inverse of f(x)=9x+7 is:

$\frac{x-7}{9}$

i.e.

$\mathrm{Inverse\:of}\:9x+7:\quad \frac{x-7}{9}$

The cost of 4 medium pizzas:

4 (x - 3)

Step-by-step explanation:

x = the cost of a large pizza

medium pizza costs $3 less than a large pizza. So it's x - 3

If 4 medium pizzas then it will be: 4 (x - 3)
