Answer:
U need to post a pic so I can see ur question
Step-by-step explanation:
First, let's review the formula for the "sum of two cubes:"
a^3 + b^3 = (a + b)(a^2 - ab + b^2).
Unfortunately, 9 is not a perfect cube. The cube root of 9 is 9^(1/3), and the square of the cube root of 9 is therefore 9^(2/3).
Thus,
9x^3 + 64 = (9^(1/3)*x + 4) * (9^(2/3)x^2 - 4*9^(1/3) + 16)
Answer: Y = X + 5.
Hope this Helps and brainliest is greatly appreciated ;)
Answer:
![(-\infty,-4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-4%5D)
Step-by-step explanation:
So we have the inequality:
This means that our solution is all numbers <em>less than or equal to </em>-4. Therefore, in interval notation, this is:
This represents all the numbers from negative infinity up until -4. This is equivalent to the inequality.
Answer:
x<-2
Step-by-step explanation:
Divide both sides of the inequality by 5 to solve for x.
