Step-by-step explanation:
If we plot -1.5 and -1.76, we would see thant -1.5 is to the right of -1.76
Right means larger here, so -1.5 is larger
Answer: 4%-16000 and 9.5%-30000
Why:
1) x+y=46000
x=46000-y
2) 4%x+9,5%y=3490;
4x + 9.5y=349000; so 4*(46000-y)+9.5y=349000;
5.5y=165000
y=30000
x=46000-30000=16000

Answer:
(D)(x-2)(x+2)
Step-by-step explanation:
As raízes do polinômio são 2 e -2, portanto sua forma fatorada tem que ser (x-x1)(x-x2) se x1=2 e x2=-2. Então:
p(x) = (x-2)(x+2)
