Step-by-step explanation:
Answer:
6 soda's will cost $9.
Step-by-step explanation:
4 soda's costs $6.
Find the amount 2 soda's will cost. Divide 2 from both sides.
(4)/2 = 2
(6)/2 = 3
2 soda's will cost $3.
Now, solve for the cost for 6 soda's by multiply 3 to both sides.
2(3) = 6
3(3) = 9
6 soda's will cost $9.

Answer:
A. 3×3
B. [0, 1, 5]
C. (rows, columns) = (# equations, # variables) for matrix A; vector x remains unchanged; vector b has a row for each equation.
Step-by-step explanation:
A. The matrix A has a row for each equation and a column for each variable. The entries in each column of a given row are the coefficients of the corresponding variable in the equation the row represents. If the variable is missing, its coefficient is zero.
This system of equations has 3 equations in 3 variables, so matrix A has dimensions ...
A dimensions = (rows, columns) = (# equations, # variables) = (3, 3)
Matrix A is 3×3.
__
B. The second row of A represents the second equation:
The coefficients of the variables are 0, 1, 5. These are the entries in row 2 of matrix A.
__
C. As stated in part A, the size of matrix A will match the number of equations and variables in the system. If the number of variables remains the same, the number of rows of A (and b) will reflect the number of equations. (The number of columns of A (and rows of x) will reflect the number of variables.)
