Which equation represent the line that passes through the points (-4,3) and (2,-12)

Can someone explain how the following Matrix can be multiplied? I thought the column of the first matrix had to match the row of

natita [175]

You are correct in thinking that the columns of the first matrix must match with the rows of the second matrix.

So for example, we can multiply a 1 x 5 matrix with a 5 x 7 matrix. The two matching '5's are directly what make multiplication possible in this case. For your problem, the first two '3's match and multiplication is possible.

The rows of the first matrix don't need to match with the columns of the second matrix.

rosijanka [135]

Answer: $5.73\ hours$ or $5\ hours\ and\ 44\ minutes$

Step-by-step explanation:

You can use the following work-rate formula:

$\frac{t}{t_A}+\frac{t}{t_B}=1$

In this case let be ${t_A}$ the time it takes for Natalie to pick 40 bushels, ${t_B}$ the time it takes for Mary to pick 40 bushels and $t$ the time it takes to pick 40 bushels if they work together.
