Answer:
187
Step-by-step explanation:
We make an equation to find the average of all three games: (139+184+x)/3=170 . x is the value of the third game to get an outcome of at least 170, and when you solve the equation you get 187.
Answer:
Step-by-step explanation:
<u>Given</u>
<u>Solving</u>
- To find f(3), substitute x = 3 in the function
- ⇒ f(3) = -2(3)² + (3) + 5
- ⇒ f(3) = -2(9) + 8
- ⇒ f(3) = -18 + 8
- ⇒ <u>f(3) = -10</u>
