The vertex is in the form (x, y).

The x value of the vertex is found using x = -b/2a.

After finding the x values, plug it into the given inequality to find the y value of the vertex.

Then express the vertex as a point in the form (x, y).

Answer:

3:0.5, 9:1.5, 6:1, 33: 5.5, 12:2, 39:6.5, 15:25.

the unit rate of eggs per 1 kg of flour = 6 eggs/1 kg of flour

Step-by-step explanation:

Usually tables go in ascending numerical order...the numbers only go up, reading from right to left. But the math for this has the numbers kind of jumping around.

3/0.5 = 9/x, then cross-multiply,

3x = 9(0.5)

3x = 4.5 then divide by 3

x = 1.5

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

3/0.5 = x/1

3 = 0.5x

6 = x

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

If you need me to keep showing the math for the rest of the table, let me know.

Answer:

x y

15 -1

12 0

9 1

6 2

3 3

0 4

Step-by-step explanation:

This is a function table. For a linear function, find the average rate of change between the listed points called slope. Then use the slope to fill in other inputs and outputs for the function.

$m = \frac{y_2-y_1}{x_2-x_1}=\frac{4-0}{0-12} =\frac{4}{-12} =- \frac{1}{3}$

This means for every 3 units made in the input, the function moves down 1 output.

x y

15 -1

12 0

9 1

6 2

3 3

0 4

6 0
