What direction will the parabola open?

$\sf \longrightarrow \: y = - {1x}^{2} + 3x + 9$

The parabola will open in Downward direction.

Remember that when the coefficient of x² is negative the parabola opens in downward direction.
When the coefficient of x² is positive the parabola opens in upward direction.

erastovalidia [21]

Answer:

5 1/5 miles

Step-by-step explanation:

Given that :

Library is located halfway between park and home ;

Distance between library and park = 1 3/10 miles

Hence, total distance between park and home :

1 3/10 + 1 3/10 = 2 6/10

The distance driven :

Home to park ; park back home

2 6/10 + 2 6/10 = 4 12/10

4 + 12/10 = 4 + 1 2/10

= 5 2/10

= 5 1/5 miles

Y=-4x+6 Find an equation for the inverse relation

kherson [118]

Answer:

Step-by-step explanation:

y = -4x + 6.....switch x and y and solve for y

x = -4y + 6 ....subtract 6 from both sides

x - 6 = -4y....divide by -4 on both sides

(x - 6) / -4 = y or y = -1/4x + 3/2 <====
