Answer:x=53/6 and y=-55/6
Step-by-step explanation:
Let the first number x
Second number b y
Sum of the numbers x+y=-1/3
x-y=18
Solve simultaneously
Using elimination method
We get
2y=-55/3
y=-55/6
Substitute for y in equation 1
x+55/6=18
x=18-55/6
x=53/6
Answer:
Step-by-step explanation:
logx
<=> logx + 2logy = a (1)
log
y=b <=> 3logx + 6logy =b (2)
(1),(2)=> logx= 
logy= 3a-b
=> log
=logy-logx=3a-b -( ) = 
log
= 
(logx+logy)=........ OK
A = Ao(x)^t
Ao = 500
A = 500(x)^t
400 = 500 (x)^1
x = 4/5
A = 500(4/5)^t << The exp eqn
