Which number line represents the graph of x ≤ 0?

If it is (greater or equal) or (lesser or equal) than the dot at the base of the line is SOLID. if it is just greater or lesser then dot at the base of the line is EMPTY. the answer is whatever line has a solid dot and all values of the line are lesser than zero.

x=7

Step-by-step explanation:

t(x) = 7x, t(x) = 49

Due to the transitive property, you can say that

7x=49

divide both sides by 7

x=7
