Answer:
x= -4
Step-by-step explanation:
distribute
combine like terms
subtract 4x from both sides
subtract 8 from both sides
divide both sides by -2
The correct answer is D the very last one.
Tan x degrees = 31
To find X use arctan.
x = arctan(31)
x = 88.15
x = 88.2 (rounded to the nearest tenth)
A. it is a hexagon (there are 6 sides) B. using the equation (n-2)180 (where n is the number of sides we get (6-2)180=4*180=720. divide 720 by 6 to get 120 for each angle of the hexagon. (it has no irregularities in it's shape so that number will be correct for them all.) C. to get that just divide 39 by 6 to get 6.5 in per side. Hope that helps:)
Answer:
A.
Step-by-step explanation:
To find the inverse of a function, first make f(x) a y
So,
y = 
-18
Then switch the x and the y
x = 
- 18
Solve, for y
