Answer:
The following are the answer:
In option a "No".
In option b "Yes".
Step-by-step explanation:
In choice a:
Ax = 0 has no nontrivial solution. A would be the three-pivot matrix, it may assume, that the function has no free variable, and only if the function has had at least one free factor are their nontrivial formulas for the equations of the form Ax=0.
It implies that since A is a 3x3 matrix, has no free variables so that it has no non-trivial choices, and Ax = 0.
In choice b:
we assume that every potential has at least one solution that is Ax=b
. If A does have a three-pivot matrix, It will be a pivot element for each row and column, and for each possible b∈ R³, Ax = b has at least one solution.

1 pound: 2.33 dollars
divide 3 by 3 to find 1. divide 7 by 3.
Answer:
A
Step-by-step explanation:
Area of the unshaded region = 95/360 * 3.14 * (5*√2)^2
Area of the unshaded region = 95/360 * 3.14 * 50
Area of the unshaded region = 41.43
Area of the entire circle = pi r^2
Area of the entire circle = 3.14 * (5√2)^2
Area of the entire circle = 157
Area of the shaded part = The whole circle's area - the unshaded part
Area of the shaded part = 157 - 41.42
Area of the shaded part = 115.57
X + y = 40
y = 9x
x + 9x = 40 (substitute 9x for y in 1st equation)
10 x = 40
x = 4
4 + y = 40 (substitute 4 for x in 1st equation)
y = 36
I'm not sure because u don't have a pic of the trapezoid.
