Martins sisters age is 14 I got this My work (could be wrong)
Its pretty simple if they said Their sum of their ages is <u>22</u> all you have to do is 22-6= 14.
Hope this helps If you have any questions ask me in the comments :D

The significance of "b" in exponential function
An exponential function is represented as:
In the above equation, parameter "b" is the rate of the function
In other words, the constant multiplier of the function.
Take for instance;
By comparison:
Another instance is:
By comparison
<u>Other significance of parameter b are:</u>
If 
then b represents a growth factor
If 
the b represents the factor of decay
i.e. b is never 0
You have to simplify each equation. You can do that by adding similar values to each other:
(the first equation)
8x²y + 7x² - 5y² + 3x - 2 + 2x²y - x² - 2y² + 3x - 4
To make it easier, arrange the values around so that similar ones are beside each other:
8x²y + 2x²y + 7x² - x² - 5y² - 2y² + 3x + 3x - 2 - 4
then add the similar values together:
8x²y + 2x²y = 10x²y
7x² - x² = 6x²
- 5y² - 2y² = -7y²
3x + 3x = 6x
(- 2)+ (- 4) = -6
and if you put them together:
10x²y + 6x² - 7y² + 6x - 6
This isn't the answer to the equation, because it's different. So repeat the process with all the other equations until you find one that is identical to the simplified version.
The answer is the second one: 8x²y + 7x² - 5y² + 3x - 2 + 2x²y - x² - 2y² - 3x - 4
Answer:
Physical and chemical changes can occur in matter. The look of material changes as a result of a physical change. Physical changes are sometimes known as phase changes. When materials change phase, they transition from solid to liquid, liquid to gas, or some other combination. If you mix materials together and see fire, bubbles, or a change in color, you might be able to see a chemical shift.
