Answer:
-125
Step-by-step explanation:
Step 1: Find g(-1)
g(x) = -5x²
g(-1) = -5(-1)²
g(-1) = -5(1)
g(-1) = -5
Step 2: Find g(-5)
g(-5) = -5(-5)²
g(-5) = -5(25)
g(-5) = -125

Answer:
18.98 pounds
Step-by-step explanation:
Let 'e' represent the number of pounds of expensive candy Ellen should use. Then 27-e is the number of pounds of less expensive candy. Her total cost is ...
1.45(27 -e) +3.74e = 27(3.06)
(3.74 -1.45)e = 27(3.06 -1.45) . . . . subtract 1.45(27)
e = 27(3.06 -1.45)/(3.74 -1.45) = 27(1.61/2.29) ≈ 18.98
Ellen should use about 18.98 pounds of the expensive candy.

<em>Additional comment</em>
We showed the solution this way because it is the generic solution to any mix problem. The fraction of the mix that is the highest-value contributor is the ratio of the difference between the mix value and the lowest contributor to the difference between contributors. Here, that fraction is ...
(3.06 -1.45)/(3.74 -1.45) = (1.61/2.29)
