Answer:
0, 5/4
Step-by-step explanation:
If 
, you get 0=0, which is obviously true.
As long as K is not 0, you can divide by k and get 
which is solved by 
Answer:
{y,x} = {-7,-3}
Step-by-step explanation:
- 3x = 2
y - 2x = -1
-3x + y = 2 -2x + y = -1
y = 2x - 1
(2x-1) - 3x = 2
- x = 3 x = - 3
y = 2x-1
x = -3
y = 2(-3)-1 = -7
Summarizing the question,
Principle(P)=$100
Rate (r)=12%=0.12
Amount (A)=3×P=$300
Time=t=?
n=no of times the interest is compouned per year=4
Then,
A=P{(1+r/n)}^(n×t)
or,300=100×{1+0.12/4}^(4×t)
or,300/100=(1+0.03)^(4×t)
or,3=1.03^(4×t)
Taking log on both sides,
log3=log[(1.03)^(4×t)]
or,log3= (4×t)×log(1.03)
or,4t=log3/log(1.03)
or,t=log3/[4×log(1.03)]
or, t=9.29175...
t=9.3 years ANS!!!

Answer:
2
Step-by-step explanation:
sqrt(120)/ sqrt(30)
We know that sqrt(a)/ sqrt(b) = sqrt(a/b)
sqrt(120/30)
sqrt(4)
2
