Answer:
overpopulation of species
Step-by-step explanation:i took the test
x² – 6x= 5
Answer:
x = 8.7 or x = 1.3
Step-by-step explanation:
x² – 6x= 5
(b/2)² = (6/2)² = 9 (Using Completing the square method)
x² – 6x + 9 = 5 + 9
(x -5)² = 14
x-5 = √14
x-5 = ±3.7
Either x-5 =3.7 or x-5 = -3.7
x = 3.7+5 or x = -3.7+5
x = 8.7 or x = 1.3
if f(x+5)=x^2 +kx+30, k= ?
find the smallest zero of f(x+5). x=?
Hope this helps :)

Answer:
k=13
x= -10
Step-by-step explanation:
f(x)=x²+3x-10
f(x+5)=
=(x+5)(x+5)+3(x+5)-10
=x²+10x+25+3x+15-10
=x²+13x+30
0=x²+13x+30
0=(x+3)(x+10)
x= -3 or -10
-10< -3
smallest zero is -10
