It's would be plus haft that number (it's a negative) and the next number would be 0

b) in the vertex.
Step-by-step explanation:
In the vertex. If the parabola opens up or down the axis of symmetry is x = a where a is the x coordinate of the vertex.

Answer:
Each mixture has the same amount of salt for every 1 cup of water.
Step-by-step explanation:
It is provided that:
- Nia mixed 1 teaspoon salt with 3 cups warm water.
- Trey mixes 1 /2 teaspoon salt with one and 1/2 cups warm water.
The ratio of the number of teaspoons of salt to the number of cups of water is 1 : 3 in Nia's solution.
On dividing the amount of salt and the amount of water by 3, the ratio will be the same.

Thus 1 : 3 is equivalent to the ratio
, which means that Nia's solution has
teaspoon of salt for every cup of water.
The ratio of the number of teaspoons of salt to the number of cups of water is
in Trey’s solution.
On dividing the amount of salt and the amount of water by
, the ratio will be the same.

So Trey’s ratio is also equal to the ratio
.
Since each mixture has the same amount of salt for every 1 cup of water, they are equally salty and taste the same.
You would go 80km. This is because a third of 280km is 80km and a third of an hour is 20minutes so just divide the speed by 3.
