Should be y-5 because you’re diving the separate bases with exponents so you have to subtract the actual exponent values
Good luck with that, that will be hard what type of stupid teacher gives that fro real.
4(x - 7) + 12 = 20
4(x) - 4(7) + 12 = 20
4x - 28 + 12 = 20
4x - 16 = 20
+ 16 + 16
4x = 36
4 4
x = 9
In hexadecimal, the number is expressed in 16 digits(the value would be 0-15). The digit varies from 0-9 for first 10 digits, then A-F for 6 last digits.Number 21 would be equal to 16+5. the first 16 is expressed as "1" and 5 is expressed as 5 so the answer would be 0x15

Answer:
22.5
Step-by-step explanation:
The average rate of change on the interval [a, b] is the ratio ...
(f(b) -f(x))/(b -a)
For your function and interval, it is ...
(f(0.5) -f(0))/(0.5 -0)
Since f(0) = 0, this reduces to ...
average rate of change = 2·f(0.5) = 2(5(0.5)² +20(0.5)) = 2(5/4 +10)
average rate of change = 22.5
