Solve the inequality. Write the solution set in interval notation.
2(5 − x) ≤ 5(x − 5)

x= ( 5,∞)

the set of numbers from 5 to infinity

Step-by-step explanation:

2(5-x)≤5(x-5)  distribute

10 -2x ≤ 5x -25  rearrange to get x's on one side, constants on the other

10 + 25 ≤ 5x +2x  Or -2x -5x ≤ -25 -10 add like terms

35 ≤ 7x  Or  -7x ≤ -35  if you have to divide by a negative  number, flip the inequality sign ! see the logic: 35/7 is 5 ≤ x -35/-7 leaves x ≥ 5  

Either way it means  5 is less than or equal to x

OR x is greater than or equal to 5

or -∞ for all numbers less than.

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

i am only able to answer the first part. i am not sure about the second part. sorry
