Answer:
Its (A), 1/9a^2
if you work out all of the other options it does not equal to the expression (3a)^-2
Step-by-step explanation:
To multiply fractions, you multiply numerator with numerator and denominator with denominator
In other words: a/b*c/d=(a*c)/(b*d)
So 1st one is (5*2)/(6*3) which is 10/18 or 5/9 simplified
2nd one is (9*5)/(10*18) which is 45/180 or 1/4 simplified
3rd one is (4*3)/(5*4) which is 12/20 or 3/5 simplified
4th one is (2*5)/(3*1) which is 10/3 or 3 1/3 if you want a mixed number

Answer:
y= 5x+10
Step-by-step explanation:
Inverse basically means y is now x and x is now y.
y= x/5 -2 becomes x= y/5 -2
Remember to always leave your equation f(x) = ...
i.e. y =...
x= y/5 -2
add 2 both sides
x+2 = y/5
multiply 5 both sides
5(x+2) = y
Hence,
y= 5x + 10
