F(x)=2x-10
y=2x-10
x=2y-10
x+10=2y-10+10 (add both sides by 10)
2y=x+10
2y/2=x+10/2 (divide both sides by 2)
y=1/2x+5
Final Answer: f^-1(x)=1/2x+5
Answer:
90 degrees
Step-by-step explanation:
Angle BGD is supplementary with angle DGE.
BGD + DGE = 180
Since angle DGE is a right angle, then Angle BGD must also be a right angle:
BGD + 90 = 180
BGD = 90
Answer:
x=2
Step-by-step explanation:
Answer:
