Answer:

1 = 6

2 12

Cross multiply:

1 * 12 = 2 * 6

Simplifying

1 * 12 = 2 * 6

Multiply 1 * 12

12 = 2 * 6

Multiply 2 * 6

12 = 12

Add '-12' to each side of the equation.

12 + -12 = 12 + -12

Combine like terms: 12 + -12 = 0

0 = 12 + -12

Combine like terms: 12 + -12 = 0

0 = 0

Solving

0 = 0

Couldn't find a variable to solve for.

This equation is an identity, all real numbers are solutions.

Suppose that y varies inversely as x, and x=9 when y=15. Find the value for k and write the function. Group of answer choices La

Radda [10]

Answer:

see explanation

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition that x = 9 when y = 15

15 = $\frac{k}{9}$ ( multiply both sides by 9 )

k = 135

y = $\frac{135}{x}$ ← equation of variation
