Answer:

The vertex is (-4, -9)

Step-by-step explanation:

The two roots are located at x = -7 and x = -1, which come from (x + 7) and (x + 1). The axis of symmetry is located halfway between these values, at x = -4. This axis passes through the vertex. The y-value at the vertex is (-4 + 7)(-4 + 1), or -9. The graph is a parabola that opens up. The vertex is (-4, -9).

MrRa [10]

The LCD of 1/6, 5/12, and 11 would be (12). For the denominators 6 and 12 the answer would obviously be 12 since 6 * 2 = 12 and 12 * 1 = 12 .

Una escuela telesecundaria tiene una pista de carreras que mide 3/5 de kilómetro. Tres alumnas corrieron las siguientes distanci

Dmitriy789 [7]

Answer:

533 1/3 m, 900 m, 4 1/8 laps

Step-by-step explanation:

A telesecundaria school has a race track that is 3/5 of a kilometer long. Three students ran the following distances: Juanita 1 1/3 laps, Esperanza 2 1/4 laps and Evelyn: 1650 m, how many meters did Juanita and Esperanza run? And how many laps did Evelyn turn?

---------------------------

1 lap = 400 m

Juanita ran:

1 1/3 laps = 4/3 laps = 4/3*400 m = 1600/3 m= 533 1/3 m

Esperanza ran:

2 1/4 laps = 9/4 laps = 9/4*400 m = 900 m

Evelyn ran:

1650 m = 1650 *1/400 = 4 50/400 laps = 4 1/8 laps
