Answer:

Step-by-step explanation:

The question is looking for an equation in slope-intercept form which is y=mx+b where m is the slope and b is the y-intercept. The y-intercept is +4, which all of the answers show, so you must find the slope.

The slope is the change in y over change in x, more commonly referred to as rise over run. So count how many units the graph changes vertically and horizontally, in this case, 1 up and 2 right, so the slope is equal to 1/2. If you have a graph where the line shifts up and left, or down and right, then the slope is negative. Additionally, one way to visually check your work is to remember slopes equal to less than -1 or greater than +1 will be steeper while fraction slopes will make the slope flatter; basically the closer to zero the less steep.

If log2 5 = k, determine an expression for log32 5 in terms of k.

lukranit [14]

Answer:

$log_3_2(5)=\frac{1}{5} k$

Step-by-step explanation:

Let's start by using change of base property:

$log_b(x)=\frac{log_a(x)}{log_a(b)}$

So, for $log_2(5)$

$log_2(5)=k=\frac{log(5)}{log(2)}\hspace{10}(1)$

Now, using change of base for $log_3_2(5)$

$log_3_2(5)=\frac{log(5)}{log(32)}$

You can express $32$ as:

$2^5$

Using reduction of power property:

$log_z(x^y)=ylog_z(x)$

$log(32)=log(2^5)=5log(2)$

Therefore:

$log_3_2(5)=\frac{log(5)}{5*log(2)}=\frac{1}{5} \frac{log(5)}{log(2)}\hspace{10}(2)$

As you can see the only difference between (1) and (2) is the coefficient $\frac{1}{5}$ :

So:

$\frac{log(5)}{log(2)} =k\\$

$log_3_2(5)=\frac{1}{5} \frac{log(5)}{log(2)} =\frac{1}{5} k$

Help! I must choose 2 to Match the graph to the equivalent standard form and intercept form.( please view the both images ) im g

allochka39001 [22]

Answer:

Step-by-step explanation:

It is the 2nd one and 4th one. The x intercepts are -1 and -3, so the factors are x + 3 and x + 1. The 4th choice is the actual equation and the 2nd is the factors
