#1 explanation:
x^4-20x^2=-64
x^4-20x^2+64=0
(find a number that multiplies to the last number aka 64 and adds up to b aka 20)
((x-4)(x-16))^2
x= -2,2,-4,4
same for #2 w different variable and numbers

Answer:
The approximate solution of the system of equations is the point (-2.7,2.1)
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (-2.714,2.143)
see the attached figure
therefore
The approximate solution of the system of equations is the point (-2.7,2.1)
Answer:
Interes ganado= €59.07
Step-by-step explanation:
Dada la siguiente informacion:
300€ durante 5 años al 0.3% de interés compuesto mensual.
<u>Para calcular el valor final de la inversión y el interés ganado, debemos usar la siguiente formula:</u>
FV= PV*(1 + i)^n
Present Value= 300
i= 0.003
n= 5*12= 60 meses
FV= 300*(1.003^60)
FV= 359.07
Interes ganado= 359.07 - 300
Interes ganado= 59.07
