Answer:

Only the 3rd table shows a proportional relation between x and y.

Step-by-step explanation:

The first table is  

x 2 3 5 6  

y 3 4 7 9

Here y is not increasing in uniform rate with x. So, the relation is not proportional.

The second table is  

x 4 6 8 10  

y 6 8 10 12

Here y is increasing in uniform rate with x, but at x = 0, y ≠ 0, Hence, the relationship is not proportional.

The third table is  

x 1 5 8 10  

y 15 75 120 150

Here, y is increasing in uniform rate with x, and  at x = 0, y = 0, Hence, the relationship is proportional.

The fourth table shows

x 3 9 10 15  

y 1 3 4 5

Here also y is not increasing in uniform rate with x. So, the relation is not proportional.

Therefore, only the 3rd table shows a proportional relation between x and y. (Answer)

Find a polynomial function that has the given zeros. (there are many correct answers.) 0, 1, 6
aev [14]
Since those are the zeros, we can say that the equation would have to be
x(x-1)(x-6), then we just expand to get x^3 - 7x^2 + 6x

Answer:  A. c = 3d

I'm gonna go with c = 3d

Step-by-step explanation:  c = 3d

After looking at the table I believe the equation would be c=3d. I came to this conclusion because (6)=3(2); (9)=3(3); (15)=3(5); 18=3(6). I really hope this helps!:)

Answer:

Step-by-step explanation:

Days  Cost

2          6

3          9

5         15

6         18

Now to find equation that models the given data we will use two point slope form.

Formula:

Substitute the values in the formula

where y denotes the number of days and x denotes the cost

Let us suppose d denotes the number of days and c denotes the cost

So, equation becomes:  

Hence an equation models the data in the table is  

So, option A is true.
