Which equation represents a proportional relationship between the x and y values? A) y + 4 = 3x B) y − 3x = 0 C) y + 5x = 6 D) y
Romashka [77]

Option is B) y-3x=0  represents a proportional relationship between the x and y values

Explanation:

Case 1 = y+4=3x

From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 4 .

Case 2: y-3x=0

From the above equation we can see that if we change the value of x, the value of y changes by proportionality.

Hence the correct option is B.

Case 3 = y+5x=6

From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 6.

Case 4 = y+1/4×x=2

From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 2.

Lichens slowly eat away at the surface of rocks. The amount of biological activity that breaks down minerals depends on how much life is in that area

BARSIC [14]

Answer:

x=\frac{1}{4}

y=-2

Step-by-step explanation:

Given:

8x + y = 0

4x-y=3

Convert your equation into matrices form

\begin{bmatrix}8&1&0\\4&-1&3\end{bmatrix}

Solve using reduced row reduction (RREF)

\begin{bmatrix}8&1&0\\4&-1&3\end{bmatrix}

\begin{bmatrix}8&1&0\\8&-2&6\end{bmatrix}

\begin{bmatrix}8&1&0\\0&-3&6\end{bmatrix}

\begin{bmatrix}8&1&0\\0&-1&2\end{bmatrix}

\begin{bmatrix}8&0&2\\0&-1&2\end{bmatrix}

\begin{bmatrix}1&0&\frac{2}{8}\\0&1&-2\end{bmatrix}

\begin{bmatrix}1&0&\frac{1}{4}\\0&1&-2\end{bmatrix}

x=\frac{1}{4}

y=-2
