Find p q for which begin pmatrix 2p amp 8 3 amp... - JAMB Mathematics 2006 Question
Find p, q for which \(\begin{pmatrix} 2p & 8 \ 3 & -5q \end{pmatrix}\)\(\begin{pmatrix} 1 \ 2\end{pmatrix}\)\(\begin{pmatrix}24 \ -17\end{pmatrix}\)
A
-4
B
45
C
4,2
D
2
correct option: d
2p x 2 + 8 x 1 = 24
(\to) 4p = 24 - 8 = 16, p = 4
3 x 1 + -5q x 2 = -17
(\to) -10q = -17 - 3
-10q = -20
q = 2
