Answer:
C. Yes, because A does not have a pivot position in every row.
Step-by-step explanation:
The pivot position in the matrix is determined by entries in non zero rows. The pivot position may be in the row or a column. By Invertible Matrix Theorem the equation Axequalsb has non trivial solution. A has fewer pivot positions therefore A is not invertible. Ax will map RSuperscript into real numbers for n times. A has pivot position if left parenthesis bold x right parenthesis.
Answer:
∠ QRS = 100°
Step-by-step explanation:
Since RU bisects ∠ QRS , then
∠ QRU = ∠ SRU , that is
x + 10 = 50 ( subtract 10 from both sides )
x = 40 ( multiply both sides by 2 )
x = 80
Then
∠ QRU =
x + 10 = 0.5 × 80 + 10 = 40 + 10 = 50°
∠ QRS = 50° + 50° = 100°
Answer:
32 > 23.
Step-by-step explanation:
We are given with 32 and 23. We need to compare them. If we use number line 32 is always greater than 23.
So, 32>23
(3x+5)(X+3) would be the factored form
