No it is not true for all cases
Ex
2 x = 5 ------1
3 x =7.5 ------2

b)True
If a linear system has free variables, then it must have infinitely many solutions.
c)False
Every linear system with the same number of equations and variables has a unique solution.This is not true for all cases.
d)True
In every linear system with 2 equations and 3 variables x1,x2,x3, the last variable x3 is a free variable.
e)True
If x1 = x2 = ··· = xn = 0 is a solution to a linear system, then the system must be homogeneous.

Answer:
D. (2, 6)
Step-by-step explanation:
Look at the picture.
Check:
(2, 6) → x = 2, y = 6
Put the coordinates of the point to the inequalities:
y < x² + 6
6 < 2² + 6
6 < 4 + 6
6 < 10 TRUE
y > x² - 4
6 > 2² - 4
6 > 4 - 4
6 > 0 TRUE
Answer:
9:34 pm
Step-by-step explanation:
First:
8:17 am
Go back 12 hours
8:17 pm
Round to 8:20
(keep the 3) Minus 43-17=26(3 is in this)
Therefore, 9:34 pm
Sorry if this doesn't make sense, it's hard to explain haha
