B & D
Step-by-step explanation:
-3 (0.15 - 0.2 + 0.25p) = - 3 * 0.15 - (-3) * 0.2 + (-3) * 0.25p
-0.45 + 0.6 - 0.75p = 0.15 - 0.75p = -3 (-0.05 + 0.25p}
Answer:
Step-by-step explanation:
The coefficients of x and y in the first equation will be the 2 x 2 matrix first row and the coefficients of x and y in the second equation will be the second row:
When you take the inverse of that 2 x 2 matrix and multiply it with the right side matrix (-16 -48), you can find the solution for x and y.
