Answer:
B. infinite solutions along a line
Step-by-step explanation:
The matrix is equivalent to the equations ...
x = 2
y = 9
0z = 0 . . . . . . true for any z
This tells you the solutions are ...
(x, y, z) = (2, 9, z)
This defines a line parallel to the z-axis.
Answer:
The number of packages of flour tortillas is a 9 multiple.
Step-by-step explanation:
Given there are only packages of flour tortillas and packages of corn tortillas on the shelf.
Let the number of flour tortillas be x and the number of corn tortillas be y
therefore the total number of packages are x+y.
Given the ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16.
which means 



since both x and y are integers y is in the form of 7k where k∈N.

Therefore x is a 9 multiple.
The answer would be 22.
You would use the order of operations to solve this problem,
First you do the parenthesis, there are none so you skip this
Then the exponents, none so skip it
Then you do multiplication and division from left to right
5•7 is 35, 3•8 is 24
So the problem is now
35-24+11
After multiplication comes addition and subtraction from left to right
35-24 is 11
11+11 = 22
So the answer to (5x7)-(3x8)+11 is 22
* This means multiplication.
^ This means exponent.
2*2 = 2×2
2^2 = 2²
Answer:
x≥11
Step-by-step explanation:
4x-3≥41
4x≥41+3 -44
x≥44/4 = 11
