Answer: Quadrant IV

Step-by-step explanation: Pic attached.

I found the x and y using substitution (isolating one variable and plugging it into the other). There was probably an easier way but I couldn't think of it at that moment.

From there, you have the point ( 133/36 , -23/18), or a (+, -).

Find Which quadrant has positive x and negative y.

In this case, this would be Quadrant IV or 4.

Hope this helps! Sorry if too complicated lol.

What is the percentage difference between 26 and 14?

topjm [15]

Answer:

0.12%

Step-by-step explanation:

Percent means out of hundred

therefore 26 in percentage is written as

$\frac{26}{100} = 0.26$

=0.26%

and 14 in percentage is written as

$\frac{14}{100}$

=0.14%

percentage difference between 26 and 14 , therefore

=0.26% - 0.14%

=0.12%

Answer:

Step-by-step explanation:

using the rule of logarithms

log x - log y ⇔ log ( $\frac{x}{y}$ )

then

$log_{b}$ ( $\frac{a}{d}$ ) = $log_{b}$ a - $log_{b}$ d
