Triangle to angle sum theorem.
m<EDB + m<DBE + m<BED = 180
90 + 50 +M<BED = 180
140 + M<BED = 180
-140 - 140
------------------------------
M<BED = 40
Answer: 0

When you know your equation f(x) and they want you to find f(-4), it means that they want to know what f(x) is worth when x=-4
Therefore, you only need to plug in you x in the equation
f(x)=5x-2
f(-4)=5(-4)-2
=-20-2
=-22 (B)
