Answer:
a=3 IF it's continuos
Step-by-step explanation:
for continuity, the left limit of the first equation must be equal to the right limit of the third equation
and they are equal, as you can see putting x=2 in both equations
to be continuos in a point c, f(x) must:
be defined in c (so f(c) exists)
the limit in c exists (in this case both from left and right)
the limit in c must be equal to f(c)
The mean for both is under 700
The mean for the second is 653.13.
The first is 683.25.
-4x + 9y = 9...............(1)
x - 3y = -6 Multiply through by 3:-
3x - 9y = -18..............(2)
adding equations (1) and (3):-
-x = -9
x = 9
Substitute for x in equation (1)
-4(9) + 9y = 9
-36 + 9y = 9
9y = 45
y = 5
Answer is x = 9 and y = 5
