Since these fractions have different denominators, we need to find the least common multiple of the denominators
The least common multiple of 2 and 9 is 18, so we need to multiply to make each of the denominators = 18

Plz, help me!!!<br> Write each interval as an inequality. Then graph the solutions. (–∞,5)
makkiz [27]

The interval notation given to us means that x is between negative infinity and 5, excluding both endpoints.

So we can write -\infty < x < 5 which shortens to x < 5

The graph will have an open hole at 5 on the number line, and shading to the left to indicate all points smaller than 5.
