In golf, the lower your score the better. Negative scores are best of all. Teri scored +1 on each of the first three holes at a nine-hole miniature golf course. Her goal is a total score of -9 or better after she has completed the final six holes. Let h represent the score Teri must avereage on each of the last six holes in order to meet her goal. Write a 2-step inequality you can use to find h

h ≤ - 2

Step-by-step explanation:

Given :

Score on each of first 3 holes = +1

Total number of holes = 9

Target score - 9 or better ≤ - 9

Number of holes left = 9-3 = 6

h = average score on each of last 6 holes to meet target score ;

3 * (+1) + (number of holes left * average score) = target score

3 + (6 * h) ≤-9

3 + 6h ≤ - 9

6h ≤ - 9 - 3

6h ≤ - 12

h ≤ - 2

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
