Answer:
6
Step-by-step explanation:
Negative six plus twelve is positive six
The second one, and the two last should be the right answer,
Hope this helped:)
If you mean y= -3x*2.5 then yes, it's linear.
To solve this, you need to know three exponent rules:1) Power of a productBasically says

. This means a product raised to a power is the same as taking each factor to that power and multiplying them.
For example:
2) Product of powersBasically says

. When two expressions with the same base (a) are multiplied, you can add their exponents while keeping the same base.
For example:
3) Power of a powerBasically says

. When an exponent is being raised to a exponent, you can multiply the exponents.
For example:

----
Back to your problem:
You are asked to simplify

, Tackle it by simplifying both factors and then multiplying them together and simplifying again.
1) First use the power of a product rule to change

into

. Simplify it into

using the power of a power rule.
2) Simplify

into

using the power of a power rule.
3) Multiply the simplified factors from part one and two and simplify using the product of powers rule:
