Step-by-step explanation:
do you actually need a explanation?
Answer:
i once took a pic of my HW on this app and got it finished in under 10 minutes
D 22-14=8 14-7=7 7 of 14=50% so i think that’s the best estimate
The equation seems to be
1
-------- = 5 ^ (x + 4)
25
In that case, this is the solution, stept by step:
1) factor 25: 25 = 5^2
1
=> ----------- = 5^(x + 4)
5^2
2) invert 5^2
=> 5^(-2) = 5^(x+4)
3) Given that the bases are equal, the exponents also have to be equal:
=> - 2 = x + 4
3) transpose +4:
=> - 2 - 4 = x
=> x = - 6
Answer: - 6
