Answer:
80%
Step-by-step explanation:
regular price is 100%
so, after the discounted price is 20%
the discount is 80%
0.2% becouse
0.002=2/1000=0.2/100
10x^2 - 25 = x^2
Take the square root of each side.
x = 10x - 5i
Using: loga b = log b / log a
1) a=x+3, b=4 → y1=log4 (x+3) → y1= log (x+3) / log 4
2) a=2+x, b=2 →y2=log2 (2+x) → y2=log (2+x) / log 2
Answer:
y1=log (x+3) / log 4, y2= log (2+x) / log 2
