question 99

Multiple Choice

Find the values of the variables for which the statement is true, if possible.
- $\left[ \begin{array} { r c c } \mathrm { a } & 1 & - 8 \\ - 5 & - 3 & \mathrm { f } \end{array} \right] + \left[ \begin{array} { r r r } 6 & \mathrm {~b} & - 4 \\ \mathrm {~d} & - 6 & - 8 \end{array} \right] = \left[ \begin{array} { r r r } 2 & - 9 & \mathrm { c } \\ - 1 & \mathrm { e } & 2 \end{array} \right]$

• A) \(a = 8 ; b = - 8 ; c = 4 ; d = - 6 ; e = 3 ; f = - 6\)
• B) \(\mathrm { a } = \frac { 1 } { 3 } ; \mathrm { b } = - 9 ; \mathrm { c } = 72 ; \mathrm { d } = \frac { 1 } { 5 } ; \mathrm { e } = 18 ; \mathrm { f } = - \frac { 1 } { 4 }\)
• C) \(\mathrm { a } = - 4 ; \mathrm { b } = - 10 ; \mathrm { c } = - 12 ; \mathrm { d } = 4 ; \mathrm { e } = - 9 ; \mathrm { f } = 10\)
• D) \(\mathrm { a } = 4 ; \mathrm { b } = 10 ; \mathrm { c } = - 4 ; \mathrm { d } = - 4 ; \mathrm { e } = - 3 ; \mathrm { f } = - 10\)
