Solve the nonlinear system of equations

Mathematics
1 answer:
Kitty [74]3 years ago
3 0

Answer:

  There are no real solutions. The complex solutions are ...

  (x, y) = (2.5-i√1.75, -2.5+i√1.75)  or  (2.5+i1.75, -2.5-i1.75)

Step-by-step explanation:

Subtract the first equation from the second.

  y -y = (x^2 -6x +8) -(-x)

  0 = x^2 -5x +8

Rewrite to facilitate completing the square:

  x^2 -5x = -8

  x^2 -5x +6.25 = -1.75 . . . . . add 6.25 to complete the square

  (x -2.5)^2 = -1.75 . . . . . write as a square

  x -2.5 = ±i√1.75 . . . . . . take the square root

  x = 2.5 ± i√1.75 . . . . . . add 2.5; y is the opposite of this

Solutions are ...

  • x = 2.5 +i√1.75, y = -2.5 -i√1.75
  • x = 2.5 -i√1.75, y = -2.5 +i√1.75

_____

The graph shows the equations have no point of intersection, meaning there are no real solutions. The complex solutions are shown above.

Evaluate v(x) = 14-3x when x=-3, 0 and 4.
PtichkaEL [24]

Answer:

v(-3)=23\\v(0)=14\\v(4)=2

Step-by-step explanation:

v(x)=14-3x

v(-3)=14-3(-3)\\\\v(-3)=14-(-9)\\\\v(-3)=23

v(0)=14-3(0)\\\\v(0)=14-0\\\\v(0)=14

v(4)=14-3(4)\\\\v(4)=14-12\\\\v(4)=2

The odds against Carl beating his friend in a round of golf are 9:7. Find the probability that Carl will lose?
grandymaker [24]

The ratio 9:7 gives you following statement:

  • Carl will win in 9 cases from 9+7=16;
  • Carl will lose in 7 cases from 16.

Then the probability that Carl will lose is

Pr(\text{Carl will lose})=\dfrac{7}{16}.

Answer: Pr(\text{Carl will lose})=\dfrac{7}{16}.
