Thank.........you......so.........much.....
Answer:
X=-2
Y=-6
Step-by-step explanation:
Since both equations are already expressed in the simplest form of y, then we equate them to be equal hence
x-4=4x+2
Bringing like terms together
-4-2=4x-x
Solving both sides
-6=3x
Making x the subject then
X=-6/3=-2
Subsrituting the value of x into any of the initial equations
Y=x-4 then y=-2-4=-6
Therefore, the solution is
X=-2
Y=-6

Answer:
(4)
Step-by-step explanation:
The fact that GH is the perpendicular bisector of EF means EM = FM and all of the angles at M are congruent.
It does not say anything about the relative sizes of HM and GM, so we cannot conclude HM and GM are congruent.
There are 1+3 = 4 people from brazil (focus on row2)
There are 4+3+2 = 9 people who scored exactly 85 points (look at column 2)
So there are 4+9 = 13 people who are from brazil or scored exactly 85 points. Subtract out those who fit both criteria. So we'll subtract off 3 people
13-3 = 10
There are 10 people who fit the criteria out of 19 total. The 19 is from adding up all the values in the table.
Divide the two values to get 10/19
Answer: 10/19
