There are two tables shown below. Which table shows a constant rate?

Option B

Step-by-step explanation:

To calculate the rate of the table is given by the expression,

Rate =

For table A,

    x              y                                            

    2             10                 -                       -              -

    3             15           15 - 10 = 5        3 - 2 = 1      

    5             20          20 - 15 = 5       5 - 3 = 2    

    8             25          25 - 20 = 5      8 - 5 = 3    

Therefore, rate is not constant in this table.

For table B

    x              y                                            

    3              9                 -                       -              -

    5             15           15 - 9 = 6        3 - 5 = 2      

    8             24          24 - 15 = 9       8 - 5 = 3    

   10             30          30 - 24 = 6     10 - 8 = 2    

Therefore, table B shows a constant rate of 3.

Option B is the correct option.

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
