Suppose a, b, c, and d are constants such that a is not zero and the system below is consistent for all possible values of f and g. what can you say about the numbers a, b, c, and d?

[tex]ax_1+bx_2=f\\cx_1+dx_2=g[/te x]

ad − bc ≠ 0

Step-by-step explanation:

If we write this system in matrix form:

"Consistent" means there exists a solution for x₁ and x₂.  That means the coefficient matrix must be invertible.  For that to be true, the determinant cannot be 0.

step-by-step explanation:

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
