Answer:
42
Step-by-step explanation:
Since Gabrielle is 7 years older than Mikhail, we subtract 7 from 91. Then we divide it by 2. So 84/2=42. Since Gabrielle is 7 years older we add 7 to 42. She is 49 and Mikhail is 42 years old. To double check our answer we should add both of the ages we got to make sure they add up to 91, so 42+49 is 91.
As the mapping suggests, the first (x) coordinate is decreased by 3, and the second (y) coordinate is increased by 2. So, given the inputs, you have


And yes, this rule is a function: it has a starting set (the domain), which is all possible couples
, and a landing set (the codomain), which is again composed by the couples
. Since for every point in the domain you have one and only one output, this rule is a function.
Answer:
85.
Step-by-step explanation:
Let x represent Bernie's highest score.
We have been given that Bernie played 3 rounds of golf, and the mean of his score was 78. His lowest score was 74.
Since Bernie's lowest score is 74, so we can assume that his score on 2nd round would be 75.
Now, we will use mean or average formula to solve our given problem.


Let us solve for x.





Therefore, the greatest possible value of his highest score would be 85.
