Answer:

Slope of the line DV = -1

Step-by-step explanation:

Let point D (-5, 1) be $(x_{1}, y_{1})$

Let point V (-1, -3) be $(x_{2}, y_{2})$

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in the appropriate values,

$m = \frac{-3-1}{-1-(-5)} = \frac{-4}{4} = -1$

slope equals -1

Solve 3x + 2 = 15 for x using the change of base formula log base b of y equals log y over log b. −1.594 0.465 2.406 4.465

disa [49]

Answer:

The value in 3x + 2 = 15 for x using the change of base formula is 0.465 approximately and second option is correct one.

Solution:

Given, expression is $3^{(x+2)}=15$

We have to solve the above expression using change of base formula which is given as

$\log _{b} a=\frac{\log a}{\log b}$

Now, let us first apply logarithm for the given expression.

Then given expression turns into as, $x+2=\log _{3} 15$

By using change of base formula,

$x+2=\frac{\log _{10} 15}{\log _{10} 3}$

x + 2 = 2.4649

x = 2.4649 – 2 = 0.4649

Hence, the value of x is 0.465 approximately and second option is correct one.
