A would either be + or -3, or + or minus 4 depending on what b is
To solve for a, you must isolate it.
<span>25=a^2+b^2
First subtract b^2 on both sides of the equation.
b^2 + 25 = a^2
Now square root both sides of the equation.

That will get rid of b^2 and make it b. Also the square root of 25 is 5. Finally it will get rid of a^2 to make a.
b + 5 = a is the answer.</span>

Step-by-step explanation:
Principal = Rs 9000
Rate = 12.5 %
Time = 5yrs
Amount=?
We know
I=p×t×r÷100
=9000×5×12.5÷100
=562500÷100
=5625
now
A=P+I
=9000+5625
14625
Y = kx
so
k = y/x
k = 2 / -3 = -2/3
