Miguel walks 3/4 mile around the high school track in 1/2 hour. How far can he walk in 2 hours? Explain.
Leno4ka [110]
2 hours is = 1/2 hour x 4
And because Miguel walked 3/4 mile in 1/2 an hour, you can multiply 3/4 by 4 to get the answer.
3/4 x 4 = 3
Miguel walked 3 miles in 2 hours.

Answer:

See below.

Step-by-step explanation:

The vertex is the lowest point of the parabola.

The vertex is (-2, 1).

The x-intercepts are the points at which the parabola intersects the x-axis. This parabola does not intersect the x-axis, so there are no x-intercepts.

The y-intercept is the point at which the parabola intersects the y-axis.

This y-intercept is (0, 2).
