Answer:
-30a⁵b + 12a⁴b² + 16a³b² - 4a²b⁴ - 2ab³
Step-by-step explanation:
( - 6a³b + 2ab²)( 5a² - 2ab² b)
multiply the second parantheses by each term from the first parantheses.
-6a³b×(5a²- 2ab²b -b)+2ab×(5a² -2ab²b-b)
-6a³b× (5a² - 2ab² b) +2ab × (5a² - 2ab² b)
-30 a⁵b + 12a⁴b² + 6a³b²+ 10a³b² - 4a²b⁴ - 2ab
combine like terms
-30a⁵b + 12a⁴b² + 16a³b² - 4a²b⁴ - 2ab³

The inequality <span>t < -6 states that t is a number that is less than -6, that is, is at the left side of -6 in the number line. Therefore from the options given, -7 in option B is the correct answer.</span>
Answer:
9
Step-by-step explanation:
FIRST convert mixed number to an improper fraction (2 1/4 converts to 9/4)
FLIP 1/ 4 ....Now its 4/1
9/4 × 4/1 = 36/4 ....Which simplifies to NINE :)
The easiest way to find the inverse of a function is to swap the x and y, meaning:
We have the function
![f(x)=5x+1](https://tex.z-dn.net/?f=f%28x%29%3D5x%2B1)
. Let's call our outputs "y", so we have
![y=5x+1](https://tex.z-dn.net/?f=y%3D5x%2B1)
. To find the inverse, we're going to change the x and the y's position in the equation, so we have
![x=5y+1](https://tex.z-dn.net/?f=x%3D5y%2B1)
. Then all we need to do is solve for y:
![x=5y+1](https://tex.z-dn.net/?f=x%3D5y%2B1)
![x-1=5y](https://tex.z-dn.net/?f=x-1%3D5y)
![\frac{x}{5}-\frac{1}{5}=y](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B5%7D-%5Cfrac%7B1%7D%7B5%7D%3Dy)
