Answer:
-10y + 11.4
I hope this helps you out
Step-by-step explanation:
1) -5n+10n
= 5n
2) -x-9+2x-10
= 2x-x-9-10
= x-19
3) -5(x-10)-x
= -5x+50-x
= -6x+50
4) 9-5(1-7x)
= 9-5+35x
= 35x+4
5) y^2-x
= 3^2-2
= 9-2
= 7

Since the square root of 3 can be re written as 3^-2 or 3^1/2, doing the same with the second factor will yield “3^1/2 • 3^1/5” thus, proceed to follow the Exponent Laws and you will have 3^1/2+1/5 which equals 3^5/10+2/10 which equals 3^7/10.
