Answer:
3rd one. The general form of a circle is set equal to the radius squared. So right side is 4 then plug in values until true.
ANSWER:
D. The answers will be different because after distributing the 4 in the first equation it will change the values.
Hope it helps u!
The annual return percentages will be evaluated using the formula:
A=P(1+r/100)^n
where:
A=amount
P=principle
r=rate
n=time
a] A=$500, P=$400, n=1 years
500=400(1+r)^1
solving for r we shall obtain:
1.25=1+r
hence
r=1.25-1
r==0.25
annual rate of investment is 25%
b] A=2500+100=$2600, P=$ 2000, n=1 year
hence
2600=2000(1+r)^1
2600/2000=1+r
1.3=1+r
r=1.3-1
r=0.3
annual rate of investment is 30%
You need another equation, other wise x can be anything, and y can be infinitely different solutions.

eso es cierto y correcto por supuesto, es tan obvio
