Answer:
C) 6
Step-by-step explanation:
Given: b(X) = l x + 4 l
Now plug x = -10 in the given function, we get
b(-10) = l -10 + 4 l
b(-10) = l -6 l
The given function is an absolute function, the absolve value is always positive.
The absolute value is nothing but distance from the origin. The distance cannot be negative. Therefore, the absolute value is always positive.
Therefore, b(-10) = 6

Answer:
D
Step-by-step explanation:
The inequality symbol is < (not ≤), which means the end point of the graph will be an open circle.
After dividing by the coefficient of x, you have an inequality of the form ...
x +( ) < ( )
which means <em>the solution will be left of the (open circle) end point</em> of the graph. Only one graph has that form.

If you actually work through the numbers, you get ...
x +8 < 9 . . . . . . divide both sides by 2.9
x < 1 . . . . . . . . . subtract 8 from both sides
