Question

1) 2 (5x + 9) < 8a) 41b) ++++ES1c) HH72d) HHHHHWhich number line matches the inequality?

Answer 1

Solution

We have the following inequality:

2(5x +9) < 8

And solving we got:

10 x +18 < 8

And subtracting 18 in both sides we got:

10x < 8 -18

10x <-10

x < -1

Then the solution for this case is:

d)

since the inequality is exclusive at x=-1
