Answer:

The constant rate of proportionality is r = 0.2

Step-by-step explanation:

We have an equation in the following format:

y = rx

In which r is the constant rate of proportionality.

To find r, we find a pair of x and y and replace.

8|1.6

This means that when x = 8, y = 1.6. So

y = rx

1.6 = 8r

8r = 1.6

r = 1.6/8

r = 0.2

The constant rate of proportionality is r = 0.2

Which is an x-intercept of the continuous function in the

TEA [102]

Answer:

The x-intercept is the value of the variable x when the value of the function is equal to zero

In the table we have

(-1, 0)(−1,0) is a x-intercept, because

For x=-1x=−1 the value of the function is equal to zero

(-6, 0)(−6,0) is a x-intercept, because

For x=-6x=−6 the value of the function is equal to zero

therefore

the answer is

the continuous function in the table has two x-intercepts

(-1, 0)(−1,0)

(-6, 0)(−6,0)
