Answer:
It is a singular matrix system.
Step-by-step explanation:
A column of all zeros in a matrices says that the variable associated with that column has no effect on the output.
For example If the first column of a matrix consists of zeros, this means that the coefficient of the first variable is zero in every equation in the system . This means that if there is any solution at all, then there must be an infinite number of them, since you can set that first variable to any value at all and still satisfy all of the equations.
Answer: at -2=9
at -1= 1
at 0=1
at 1= 9
at 2=25
Step-by-step explanation:
F(x)= (2x + 1)²
at -2
F(x) = (2(-2) + 1)²
= (-4+1)²
=(-3)²
=9.
Same goes with all points
The two lines are parallel.
Answer:
Step-by-step explanation:
Your equation comes out to x + 3 = x/3. Multiplying all three terms by 3 results in 3x + 9 = x, which simplifies to 2x = -9, so that x = -9/2.
