Answer:
I think it is correct and is 1 and 2
Step-by-step explanation:
5×4^(x+1)-16^x=64
0=64+16^x-5×4¹×4^x
0=(4^x)²-2×4^x×10+10²-10²+64
0=(4^x-10)²-36
(4^x-10)²=36
4^x-10=√36
4^x=+-6+10
when positive
4^x=4²
:.x=2
when negative
4^x=4
:.x=1
:.x=1,2 answer.
x = -10
9x-1=10x+9
9x-1+1=10x+9+1
9x=10x+10
9x-10x=10x-10x+10
-x=10
-x/-1=10/-1
x= -10
hope it's helpful ❤❤❤❤❤❤
THANK YOU.

y=5x+10 or y=25 (i'm not sure what they're asking)
There are eight books total and he only grabbed two so the probability would be 2 out of 16 or 2:16
