Solve the system by using a matrix equation
3x-5y=3
3x-4y=3
2 answers:
Answer: B. (1,0)
Step-by-step explanation:
1. We will use the matrix method to solve this problem.
3 -5 3
3 -4 3
2. Apply to Row2 : Row2 - Row1.
3 -5 3
0 1 0
3. Simplify rows.
3 -5 3
0 1 0
Note: The matrix is now in row echelon form.
The steps below are for back substitution.
4. Apply to Row1 : Row1 + 5 Row2.
3 0 3
0 1 0
5. Simplify rows.
1 0 1
0 1 0
Note: The matrix is now in reduced row echelon form.
6. Therefore,
x=1
y=0
or (1,0).
Answer:
The correct answer is B. (1,0).

Answer:
0.96*10 is 9.6.
Step-by-step explanation:
Answer:
9. y = 8
10. n = 21
11. 44 = v
12. c = 35
Step-by-step explanation:
9. 9y = 72
Divide each side by 9
9y/9 = 72/9
y = 8
10. 3n = 63
Divide each side by 3
3n/3 = 63/3
n = 21
11. 4 = v/11
Multiply each side by 11
4*11 = v/11*11
44 = v
12. c/7 = 5
Multiply each side by 7
c/7*7 = 5*7
c = 35
Answer:
c if i'm correct but its possible that its c
