19) Albert says that the two systems of equations shown have the same solutions.
k0ka [10]

Answer:

option A) Agree, because the solutions are the same is correct.

Step-by-step explanation:

FIRST SYSTEM

6x + y= 2

-x-y=-3

solving the system

\begin{bmatrix}6x+y=2\\ -x-y=-3\end{bmatrix}

\mathrm{Multiply\:}-x-y=-3\mathrm{\:by\:}6\:\mathrm{:}\:\quad \:-6x-6y=-18

\begin{bmatrix}6x+y=2\\ -6x-6y=-18\end{bmatrix}

adding the equation

-6x-6y=-18

+

\underline{6x+y=2}

-5y=-16

so the system becomes

\begin{bmatrix}6x+y=2\\ -5y=-16\end{bmatrix}

solve -5y for y

-5y=-16

Divide both sides by -5

\frac{-5y}{-5}=\frac{-16}{-5}

simplify

y=\frac{16}{5}

\mathrm{For\:}6x+y=2\mathrm{\:plug\:in\:}y=\frac{16}{5}

6x+\frac{16}{5}=2

subtract 16/5 from both sides

6x+\frac{16}{5}-\frac{16}{5}=2-\frac{16}{5}

6x=-\frac{6}{5}

Divide both sides by 6

\frac{6x}{6}=\frac{-\frac{6}{5}}{6}

x=-\frac{1}{5}

Therefore, the solution to the FIRST SYSTEM is:

x=-\frac{1}{5},\:y=\frac{16}{5}

SECOND SYSTEM

2x-3y = -10

-x-y=-3

solving the system

\begin{bmatrix}2x-3y=-10\\ -x-y=-3\end{bmatrix}

\mathrm{Multiply\:}-x-y=-3\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-2x-2y=-6

\begin{bmatrix}2x-3y=-10\\ -2x-2y=-6\end{bmatrix}

-2x-2y=-6

+

\underline{2x-3y=-10}

-5y=-16

so the system of equations becomes

\begin{bmatrix}2x-3y=-10\\ -5y=-16\end{bmatrix}

solve -5y for y

-5y=-16

Divide both sides by -5

\frac{-5y}{-5}=\frac{-16}{-5}

Simplify

y=\frac{16}{5}

\mathrm{For\:}2x-3y=-10\mathrm{\:plug\:in\:}y=\frac{16}{5}

2x-3\cdot \frac{16}{5}=-10

2x=-\frac{2}{5}

Divide both sides by 2

\frac{2x}{2}=\frac{-\frac{2}{5}}{2}

Simplify

x=-\frac{1}{5}

Therefore, the solution to the SECOND SYSTEM is:

x=-\frac{1}{5},\:y=\frac{16}{5}

Conclusion:

As both systems of equations have the same solution.

Therefore, we conclude that Albert is right when says that the two systems of equations shown have the same solutions.

Hence, option A) Agree, because the solutions are the same is correct.

Vlad [161]

BRAINLIEST ANSWER PLEASE

Answer:

Jim- Ocean

Darrell- Lake

Janet- Mountains

Stephanie- Desert

Step-by-step explanation:

If you read throughly Jim loves to surf the only place to surf is in the ocean because most lakes you cant surf.

Darrell live by a lake because it said there was water near him and Jim loves to surf EACH MORNING which clearly would mean he lives near an ocean so Darrell would live by a lake

Stephanie lives in the desert because she don't like the mountains

Janet live in the mountains because its the last option
