2) Uma equação foi descrita da seguinte maneira: (k² – 4) x³ + ( k – 2 )x² + 7x - 8 = 0
Analisando os coeficientes, o valor de k que faz com que essa equação seja uma equação do 2º grau é:
a) k = ± 2
b) k = + 2
c) k = - 2
d) k = 0
e) k = 4

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
