The answer in 28 years old because you add all the numbers together which is 336 and then divide by how many numbers there are which is 12 and that equals 28 which is the average.
Hello:
6x²+1 = x²+4
5x² = 3
x² = 3/5
the system has two solutions ( X² =b ..b> 0 has two solutions : ± <span>√b)
</span>x = √(3/5) or x = - √(3/5)
if : x = √(3/5) y = √(3/5) ² +4 =3/5 +4 =23/4
if : x = - √(3/5) y =(- √(3/5)) ² +4 =3/5+4 =23/4
<span>The graphs of the equations intersect each other at two places (points) :
A(</span>√(3/5) , 23/4) and B (-√(3/5) , 23/4)
Answer:
D
