las edades de maría y susana suman 56 años si la edad de maría es los 3/5 de la edad de susana ¿ que edad tiene maría?
Murljashka [212]
Susana=s
maria=m

m= 3s/5 

s+m=56
s+(3s/5)=56
(5s+3s)/5=56
8s=56*5
8s=280
s=280/8
s=35

35 --->5/5
x  ---> 3/5

x= (3/5)*35 / (5/5)
x=21

If a quadratic equation has a discriminant that equals zero, which of the following statements is always true?
kotegsom [21]

Answer:

d. The equation has one solution and there is not enough information to determine the direction of the parabola.

Step-by-step explanation:

For a general quadratic equation

y = ax² +bx +c

the solution is

x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

The discriminant (D) is the part of the quadratic formula underneath the radical: b² - 4ac.

D tells us whether there are

  • two different real solutions
  • two identical real solutions ("one solution")
  • two complex solutions.

If D= 0,

x = \dfrac{-b}{2a}\pm0 = \mathbf{\dfrac{-b}{2a}}

and there are two identical solutions ("one solution").

The direction of the parabola depends on the sign of a.

That information is not given, so we cannot determine the direction of the parabola.
