Answer:

(-1/2, 23/4)

Step-by-step explanation:

Vertex of graph: -b/2a

b=1

a=1

Therefore, -1/2 is your x-value

Solve for y: y=1/4-1/2+6

y=5 3/4 or 23/4

Therefore your vertex is: (-1/2, 23/4)

hram777 [196]

Answer:

The length of Ann's toy fish is 12 inches; the length of Carol's toy fish is 17 inches; and the length of Liz's toy fish is 33 inches.

Step-by-step explanation:

Let's say Carol's fish is c inches long, Ann's is a inches long, and Liz's is l inches long. Then:

c = 5 + a

l = 9 + 2a

a = 12

Plug 12 in for a to find c and l:

c = 5 + a = 5 + 12 = 17 inches

l = 9 + 2a = 9 + 2 * 12 = 9 + 24 = 33 inches

Thus:

The length of Ann's toy fish is 12 inches; the length of Carol's toy fish is 17 inches; and the length of Liz's toy fish is 33 inches.
