Answer: x=3

Step-by-step explanation:Step 1: Simplify both sides of the equation.

(8x-11)-(15-x)=1

(8x-11)+-1(15-x)=1 (distribute the negative sign)

8x+-11+-15+x=1

8x+x+(-15+-11)=1 (combine like terms)

9x+-26=1

Step 2: Add 26 to both sides

9x-26+26=1+26

9x=27

Step 3: Divide both sides by 9.

9x/9=27/9

x=3

Answer:

x = 3

Step-by-step explanation:

First open the brackets. While opening brackets, you've to be careful about signs. So when you open bracket of (15-x), there's negative sign in front of it, so it makes the signs inside the brackets to change. Then you solve the it.

Answer:

The volume of a cylinder:

$V \approx 150.796$ $ft^3$

Step-by-step explanation:

To find the volume of a cylinder, you need the this formula:

$V = \pi r^2h$

-Use the given height and radius for the formula:

$V = \pi 4^2 3$

-Then, solve the formula:

$V = \pi \times 4^2 \times 3$

$V = \pi \times 16 \times 3$

$V = \pi \times 48$

$V = 48\pi \approx 150.796$

So, the volume of a cylinder is approximately $150.796$ $ft^3$ .

Given an exponential function for compounding interest A(x)= P(.82)^x what is the rate of change

Katena32 [7]

Answer:

For the answer to the question above, it is -18% because to find rate we subtract the rate, in this case, is .82 or 82% - 1 or 100% and that would give you the rate, in this case, its decreasing by an 18%
