question 145

Multiple Choice

Solve the formula for the specified variable.
- $- 6 \mathrm { k } + \mathrm { ar } = \mathrm { r } - 9 \mathrm { y }$ for $\mathrm { r }$

• A) \(r = \frac { a - 1 } { 6 k - 9 y }\) or \(r = \frac { 1 - a } { - 6 k + 9 y }\)
• B) \(r = \frac { - 6 k + a } { 1 - 9 y }\) or \(r = \frac { 6 k - a } { 9 y - 1 }\)
• C) \(r = \frac { 6 k - 9 y } { a - 1 }\) or \(r = \frac { - 6 k + 9 y } { 1 - a }\)
• D) \(r = \frac { - 6 k + 9 y } { a - 1 }\) or \(r = \frac { 6 k - 9 y } { 1 - a }\)
