PLEASE HELP I'm having trouble ​
Anastasy [175]

Answer:

c_{11}=56.1

c_{12}=12.1

c_{13}=236

Step-by-step explanation:

  • The product of two matrices X_{m\times{n}} and  Y_{n\times{r}} equals a matrix M_{m\times{r}}, where the first element of the subscript represents the amount of files of the matrix and the second element represents the amount of columns of the matrix.
  • Then, in this case  A_{1\times{3}}   B_{3\times{3}}, therefore, its product will result a matrix C_{1\times{3}}.
  • Because C matrix is going to have an only file and three columns, we now have to find the values of the elements in each column, based on the elements of A and B.
  • Commonly, to obtain the values of the resulting matrix, we just have to multiply each file of the first matrix by each column of the second matrix and sum, as follows:
  1. c_{11}=77\times1.2+39\times2.2-33\times3.7=56.1
  2. c_{12}=77\times1.4+39\times1.1-33\times4.2=12.1
  3. c_{13}=77\times3.1+39\times5.6-33\times6.7=236
  • Finally, C matrix is \begin{pmatrix}\56.1 & 12.1& 236\end{pmatrix}

A line containing the points (4, y) and (-3, 2) has a slope of 3/2.
Sonbull [250]

Answer:

y=14.5

Step-by-step explanation:

A slope of 3/2 means that for every unit it moves to the right, it will move 1.5 units up. The x of 4 is 7 more than the -3 of our other point. 7*1.5=12.5, and 12.5+2=14.5.
