Answer:

Inverse should be (-2y^2 + 4)/(ln 3)

Step-by-step explanation:

Find Y, for reversed roles/position of X and Y. Cancel out square root with ^2. Cancel out -2 by multiplying. Then, add 4 to both sides to cancel them out. Finally, nature log it and divide it to isolate X.

X + 2y = 5 x - 3y = 7 What is the value of the y-determinant? -2 -1 2

grandymaker [24]

Answer:

y-determinant = 2

Step-by-step explanation:

Given the following system of equation:

x + 2y = 5
x - 3y = 7

Let's represent it using a matrix:

$\left[\begin{array}{ccc}1&2\\1&-3\end{array}\right] = \left[\begin{array}{ccc}5\\7\end{array}\right]$

The y‐numerator determinant is formed by taking the constant terms from the system and placing them in the y‐coefficient positions and retaining the x‐coefficients. Then:

$\left[\begin{array}{ccc}1&5\\1&7\end{array}\right]$
