Which classification describes the following syastem of equations? x=5 y=6 -x - y +z = 0
Papessa [141]

Answer:

Is a consistent independent system

Step-by-step explanation:

we know that

If a system has at least one solution, it is said to be consistent .  

If a consistent system has exactly one solution, it is independent .  

If a consistent system has an infinite number of solutions, it is dependent

If a system not have solution, it is said to be inconsistent

we have

x=5 ----> equation A

y=6 ----> equation B

-x-y+z=0 ----> equation C

substitute equation A and equation B in equation C

-5-6+z=0

Solve for z

z=11

The solution is the point (5,6,11)

The system has only one solution

therefore

Is a consistent independent system

Mike wants to save $1,750 in the next 12 months. He plans to save $150 each month for the first 11 months.
podryga [215]

Answer:

$1650

Step-by-step explanation:

Based on the question, we don't need the information that Mike wants to save 1750 in 12 months.

We just need to focus on how he is saving 150 every month, for 11 months.

150*11=1650

He will save $1650 if he saves $150 every month for 11 months.

Someone help me pls.....
trapecia [35]

Answer:

\dfrac{-x+5}{6x^2-x-12}

Step-by-step explanation:

The denominators are the same. You can add the numerators without any extra work.

=\dfrac{(4x+5)-(5x)}{6x^2-x-12}=\dfrac{-x+5}{6x^2-x-12}

The denominator factors as (2x-3)(3x+4), so there are no factors that will cancel with the numerator.
