The matrix represents the system:

-3x+5y=15

2x+3y=-10, which is choice c. 


We can see it more clearly from the way we multiply matrices, as follows:

\[
  \left[ {\begin{array}{cc}
   -3 & 5 \\
    \ 2  & 3 \\
  \end{array} } \right]
\] \cdot  \[
  \left[ {\begin{array}{c}
   x \\
    y \\
  \end{array} } \right]
\]= \left[ {\begin{array}{c}
   -3\cdot x+5\cdot y \\
    2\cdot x+3\cdot y \\
  \end{array} } \right]
\]= \[ \left[ {\begin{array}{c} 15 \\ -10 \\ \end{array} } \right] \]

Answer: C

0.4x - 1.2 = 0.15x + 0.8 ?????????
valentina_108 [34]

Answer:

x = 8

Step-by-step explanation:

0.4x - 1.2 = 0.15x + 0.8

0.4x - 1.2 + 1.2 = 0.4x

0.15x + 0.8 + 1.2 = 0.15x + 2

0.4x = 0.15x + 2

0.4x - 0.15x = 0.25x

0.15x + 2 - 0.15x = 2

0.25x = 2

0.25x / 0.25 = x

2 / 0.25 = 8

x = 8
