Answer:

3b^(4/5) * (5b + 3)

Step-by-step explanation:

Factor:

$15b^{9/5} + 9b^{4/5}$

Take out the factor 3b^4/5

$3b^{4/5}(5b) + 3b^{4/5}(3)$
$3b^{4/5}(5b + 3)$

Answer:

RVS is equal to 180 - 26 degrees, or 154 degrees.

Bonus: I assume the next part of the question asks you to solve for x, where x is equal to that angle. If so, then the answer is 15:

154 = 10x + 4

150 = 10x

x = 15

Use technology to approximate the solution(s) to the system of equations to the nearest tenth of a unit. Select all that apply.

We can use using graphing technology to solve the system of equations here.

So draw sketch of graphs $y = 8^{(x-9)}$ and $y = log (3x) +2$ on graphing calculator. you will get sketch as shown

Take pointer to point of intersection as shown. It displays (x,y) coordinate of points of intersection as (9.597, 3.459) as show in figure.

Now round off these values to nearest tenth thats one digit after decimal dot.

so to round 9.597 to one decimal place we will see 2nd decimal digit(next to place where you have to round off) which is 9 here and as 9 is greater than 5 so we will increase 1st decimal place digit by 1, so round to one decimal place will be 9.6.

Similarly to round off 3.459 to one decimal place we will see 2nd decimal digit which is 5. Again as its equals 5 we will increase the 1st decimal digit by 1 for round off. So final round off to one decimal place will be 3.5

So final answer for solution set will be choice C (9.6, 3.5)
