These two matrices are unable to be added due to dimensional mismatch? True, false, both, unable to answer with the info given
Hoochie [10]

Answer:

false

Step-by-step explanation:

\left[\begin{array}{c}-4\end{array}\right] +\left[\begin{array}{c}7\end{array}\right] =\left[\begin{array}{c}3\end{array}\right]

Both of the matrices are 1 x 1 ("one by one"), so they can be added to produce a 1 x 1 matrix.

To add (or subtract) two matrices, they must be the same size.

(m x n) + (m x n) = (m x n)

m x n  means a matrix has  m  rows and  n  columns.  Dimensions are always named in that order:  rows, then columns.

Find the slope of the line on the graph. Write your answer as a fraction or a whole number, not a mixed number or decimal. ​
Zolol [24]

Answer:

apologies the answer's 3. I didn't realize it was talking about slope.

Step-by-step explanation:

Use Rise/Run and "b" is just the y intercept, which is the point where the line intersects the y-axis, in this case b=2. Hope this helped.
