Answer:
B, C, E, & F
Step-by-step explanation:
Option A is incorrect because the equation Ax = b is referred to as a matrix equation, not a vector equation.
Option B is correct. If Ax = b has a solution, vector b will a linear combination of columns of matrix A.
Option C is correct. In a matrix equation, product Ax when defined, is a sum of products.
Option D is incorrect. If an augmented matrix [Ab] had a pivot position in every row, there could be a pivot in the last column which would make it inconsistent.
Option E is correct. If the columns of an m×n matrix A span
, then the equation Ax=b is consistent for each b in
Option F is correct. IfA is an m x n matrix whose columns do not span, then the equation Ax = b is inconsistent for some b in
Options B, C, E, and F are correct.

Not sure about the weird echo in the question but I think we're being ask to evaluate
4 - 0.25g + 0.5h
when g=10, h=5
That's
4 - 0.25(10) + 0.5(5) = 4 - 2.5 + 2.5 = 4
Answer: 4
Answer:
3 men = Rs. 6000 = 4 days
Step-by-step explanation:
→ Find how much 1 man make in 3 days
1 man = Rs. 1500 = 3 days
→ Find how much he makes in 1 day
1 man = Rs. 500 = 1 day
→ Find how much one man can make in 4 days
1 man = Rs. 2000 = 4 days
→ Find how much 3 men will make
3 men = Rs. 6000 = 4 days

Step-by-step explanation:
Answer:
x = 19
Step-by-step explanation:
The two angles with measures are supplementary.
6x + 9 + 4x - 19 = 180
10x - 10 = 180
10x = 190
x = 19
