Given y varies inversely as x, and y = 5 when x = 9. *Write the inverse function
Ivahew [28]

Answer:

y = 45/x

Step-by-step explanation:

Here, we want to write an inverse relationship

for an inverse relationship, the product of both variables will be equal to the constant term

Let us have the constant term as k

Thus, we have it that;

xy = k

9 * 5 = k

k = 45

So the inverse function is;

xy = 45

or y = 45/x

if y is a function of x, we can have it as;

f(x) = 45/x

Solve for x.<br> 3(15 - x) = 2x
Morgarella [4.7K]

Answer:

well

Step-by-step explanation:

3 times 15 is 45

then 3 times negative x is -3x

so 45 - 3x = 2x

3 x moved to the other side turns positive

so you have

5x = 45

45÷5

x = 9
