Step-by-step explanation:

One of the logarithm rules states the following:

log{a} - log{b} = log{\frac{a}{b}}

For this problem, that means the following:

log{2x + 3} - log{x - 1} = log{\frac{2x + 3}{x - 1}}

So now we have the following:

log{\frac{2x + 3}{x - 1}} = 3

Rolling the log, we get the following:

10^{3} = \frac{2x + 3}{x - 1}

Answer:

Initial value

Initial value never changes, whatsoever.

Slope is either a constant increase or decrease.

Unit rate, rate of change, and "per" all describe a rate at a certain point which is always fluctuating.

A parabola with its vertex at (24,10) and its axis of symmetry parallel to the y-axis passes through point (4,290). Write an equ
andrew-mc [135]

Answer:

               Not executable

Step-by-step explanation:

f(x) = a(x - h)² + k      - vertex form of the equation of the parabola with vertex (h, k)

so the equation of parabola with the vertex (24, 10) is  :

f(x) = a(x - 24)² + 10  

the parabola's axis of symmetry parallel to the y-axis and passing through point (4,290) means:  h = 4

<h3> 4 ≠ 24</h3>

That  means you write something wrong in your question.
