which number is a solution of the inequality six lower than Z(10-z)

Answer 1

To find the solution(s) of the inequality "six lower than z(10-z)", we can set up the inequality as:

z(10-z) - 6 ≥ 0

Expanding the expression on the left side, we get:

10z - z^2 - 6 ≥ 0

Rearranging the terms, we have:

-z^2 + 10z - 6 ≥ 0

To solve this inequality, we can graph the quadratic equation y = -z^2 + 10z - 6 and find the regions where y ≥ 0.

Using a graphing calculator or plotting the equation, we find that the inequality is satisfied within the following intervals:

z ≤ 1.7746 or z ≥ 8.2254

These are the values of z that are solutions to the inequality "six lower than z(10-z)".

Answer 2

wrong again!
5-√19 ≤ z ≤ 5+√19
or,
0.641 ≤ z ≤ 9.359

Answer 3

Apologies for the previous incorrect response. You are correct.

The correct solution to the inequality "six lower than z(10-z)" is:

5-√19 ≤ z ≤ 5+√19
or,
0.641 ≤ z ≤ 9.359
