Question

For each value of y, determine whether it is a solution to 2y> 18.
​

Answer 1

Explanation:

We have 4 value of y : 8 ; 11 ; 12; 6

To determine whether it is a solution to the inequality 2y > 18, we have to substitute these values in

Substitute 8 in, we get : 2 x 8 > 18
16 > 18 (not true)
So, this is not a solution


Substitute 11 in, we get : 2 x 11 > 18
21 > 18 (true)
So, this is a solution

Substitute 12 in, we get : 2 x 12 > 18
24 > 18 (true)
So, this is also a solution

Substitute 6 in, we get : 2 x 6 > 18
12 > 18 (not true)

So, this is not a solution

There are 2 values that satisfy this inequality for y : 11 and 12

Answer 2

2y>18......

2(8)= 16>18 no

2(11)= 22>18 yes

2(12)= 24>18 yes

2(6)= 12>18 no
