\log_{4} x + \log_{4} (x+5) = 6

irina1246 [14]

log(4)x + log(4)(x + 5) = 6
log(4)x + log(4)x + log(20) = 6
 log(8)x + log(20) = 6
 - log(20) - log(20)
 log(8)x = 6 - log(20)
 log(8) log(8)
 x ≈ 0.999

Someone plz help asap

Answer:

As the slope is -2, so the rate of change of the function is:

rate of change of function = -2

Step-by-step explanation:

The slope is basically the rate of change of a function.

Let us take the two points from the graph

(0, 5)

(4, -3)

Taking the slope between two points to determine the rate of change of a function

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(0,\:5\right),\:\left(x_2,\:y_2\right)=\left(4,\:-3\right)$

$m=-2$

As the slope is -2, so the rate of change of the function is:

rate of change of function = -2
