Answer:

The graph has a minimum.
The graph has a y-intercept at (0, -3).
The solutions ... are -1 and 3.
The vertex is located at (1, -4).
In the equation, 'a' would be positive.

Step-by-step explanation:

When the graph has a low point, it has a minimum. 'a' is positive in that case. The coordinates of that low point are (1, -4). That point is the vertex.

The graph crosses the y-axis at y = -3, so the y-intercept is (0, -3).

The graph crosses the x-axis at (-1, 0) and (3, 0). These points represent the solution to the equation y = 0.

The graph has a minimum.
The graph has a y-intercept at (0, -3).
The solutions ... are -1 and 3.
The vertex is located at (1, -4).
In the equation, 'a' would be positive.

Answer:Well, I don't know what you got so I can't tell you if it is right.

If it works in both equations, it depends of whether your equations are set up correctly.

Here is how I would do this problem.

Let x = no. of hot dogs,y = number of sodas.

First equation is just about the number of things.

x + y = 15

Second equation is about the cost of things.

1.5 x + .75 y = 18

solve x+y = 15 for y y = 15-x substitute into second equation

1.5x + .75(15 - x) = 18

You should get the correct answer for number of hot dogs if you solve this correctly. Put your answer in the x + y =15 equation to get y. Then put both x and y into the cost equation and check your answer.

Hope this helps.

Write a unit rate for the situation. $1.98 for 6 bananas

USPshnik [31]

A unit rate is when you find a rate when one variable (or value) is equal to one.

Let's find the unit rate for the price of the bananas.

1.98/6= 0.33

It is 33 cents for one banana. That is the unit rate.

I hope this helps!
