Answer:

Step-by-step explanation:

9 = (1/27)^(a+3)

3² = (3^-3)^(a+3)

3² = 3^(-3a-9)

2 = -3a-9

-3a = 11

a = -11/3

How would you Simplify this???????????

Korvikt [17]

Lets solve this problem:(5x^2)(5x^2)^2

so first of all you would do the () first

so lets do the first one first. 5x^2 = 5*5 wich would equal 25

so the () by each other means multiply

so now its: 25*(5x^2)^2

5x^2= 5*5=25

now its: 25*25^2

do 25^2 first: 25 * 25 =625

625*25

625*25=15,625

your answer 15,625

Having trouble with this one can someone teach me how to find the slope in this question. Try to help me learn it aswell. Its in

ASHA 777 [7]

Hi there! The answer is -2.

We can find the slope of a formula by using the following formula:

$slope = \frac{change \: of \: y}{change \: of \: x} =\frac{y2 - y1}{x2 - x1}$
x2 and y2 don't mean squared, but the x and y coordinate of our second point.

First we need to find two points on the line. Ijn this particular case we have (-3, 3) and (1, -5). Now we can fill in the formula.

$slope = \frac{ - 5 - 3}{1 - - 3} = \frac{ - 8}{4} = - 2$

Therefore, the third answer is correct.
~ Hope this helps you!
