B)F(x)= -1000X+2000
estersbarc:
A) X= -b
Soluções para a tarefa
Respondido por
1
f(x) = 0
f(x) = - 200 + 100x
0 = - 200 + 100x
200 = 100x
100x = 200
x = 200/100
x = 2
b)
f(x) = - 1000x + 2000
0 = - 1000x + 2000
1000x = 2000
x = 2000/1000
x = 2
f(x) = - 200 + 100x
0 = - 200 + 100x
200 = 100x
100x = 200
x = 200/100
x = 2
b)
f(x) = - 1000x + 2000
0 = - 1000x + 2000
1000x = 2000
x = 2000/1000
x = 2
