-2x=4x+9 |-4x
-6x=9 |:(-6)
x=-1,5
Check:
-2*-1,5=4*-1,5+9
3=-6+9
3=3
Quadrant 2 because it goes to the left because the X is negative then up because the Y is positive.
Answer:
Step-by-step explanation:

F^-1(x) is the inverse so...
f^-1(x) = (-1/5)x - 11/5
Pemdas
so do parenthaseese first
work inside then out
(25 times 2)
(50)
now we have
96/42+(50)-15-3=?
start from the begining again of the equation (left) now we do division
96/42=16/7
now we have 16/7+(50)-15-3
start over and do addition
16/7+50=2 and 2/7+50=2+2/7+50=52 and 2/7
subtract
52 and 2/7-15=52+2/7-15=37 +2/7=37 and 2/7
then subtract 3
37 and 2/7-3=37+2/7-3=34+2/7=34 and 2/7
answer is 34 and 2/7
