When you multiply powers, you add them. You keep the constant (2) the same.
3+18= 21
2^21 <=== the answer
“D” is the answer.
I hope this helps!

Go over 9x and that should be it
D+n=25 subtract d from both sides *(if your wondering what d and n are it stands for Dimes and Nickels)* n=25-d
0.10d+0.05= 1.85
0.10d+0.05(25-d)= 1.85
0.10d+1.25-0.05d= 1.85
0.05d = 0.60

My answer: He has 12 dimes (d=12) and 25-12=13 so 13 nickels.. Hope this helps! :)
Answer:
Step-by-step explanation:
To find the inverse of a function, simply switch the 'x' and 'y' variables. Substitute in 'y' in the place of f(x) for this purpose:
y = 2x - 10
Switch positions:
x = 2y - 10
Add '10' to both sides to begin simplifying:
x + 10 = 2y
Divide both sides by 2:
This can be rewritten as:
Therefore, the inverse of the function is:
It is 5389.030 to nearest hundredth
