Given:
The given value is 
.
To find:
The multiplicative inverse of .
Solution:
We know that 
is the multiplicative interval of 
if 
.
Let be the multiplicative inverse of the given value . Then,
Divide both sides by .
Therefore, the multiplicative inverse of is 
. Hence the correct option is A.
X + 0.5y = 3
x^2 - y = 15
from the first equation:-
0.5y = 3 - x
y = 6 - 2x
Substitute for y in second equation:-
x^2 - (6 - 2x) = 15
x^2 + 2x - 21 = 0
x = [-2 +/- sqrt((4 - 4*-21)] / 2
= 3.6904 , -5.6904
Plugging in these into first equation we get
3.6904 + 0.5y = 3 so y = 2(3-3.6904) = -1.3808
-5.6904 + 0.5y = 3 so y = 2(3 + 5.6904) = 17.3808
Solution is x = 3.690, y = -1.381 ; x = -5.690, y = 17.38 ( to 4 s.f's)

Answer:
9y + 13
Step-by-step explanation:
a number would best represent as a variable (doesn't matter which letter)
plus thirteen would represent an addition to 13
