Which table shows a function that is decreasing only over the interval

Table 4th is showing the function that is decreasing only over the interval

Step-by-step explanation:

We have been given four tables below:

To determine the function that is decreasing only in the given interval

We will check the values after -1 in all four tables

The table in which values is only  decreasing after -1 will be the table which shows a function is decreasing only.

In table 1 the value of x is increasing

In table 2 and 3 the value is increasing and then decreasing but we will consider only decreasing case

Therefore, Table 4th is correct.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
