Answer:
Hence, the set of values that holds true is:
2-3-4
Hence, option: D is true.
Step-by-step explanation:
We are asked to find which set of the values make the following inequality:
2x-1<10 true.
i..e we will put the given set of value s in place of xx and check whether the value of 2x-1 is less than 10 or not.
If it is then the set of values hold true.
A)
10-15-20
put x=10
2x-1=2×10-1
=20-1
=19 which is not less than 10.
Hence, option: A is incorrect.
B)
5-7-9
when x=9
2x-1=2×9-1
=18-1
=17 which is not less than 10.
Hence, option: B is incorrect.
C)
4-6-8
when x=8
2x-1=2×8-1
=16-1
=15 which is again not less than 10
Hence, option: C is incorrect.
D)
2-3-4
when x=2
2x-1=2×2-1
=4-1
=3<10
when x=3
2x-1=2×3-1
=6-1
=5 < 10
when x=4
2x-1=2×4-1
=8-1
=7<10
Hence, option: D is true.
Hence, the set of values that holds true is:
2-3-4
