What are the solutions of x2 = 8 - 5x?

Mathematics

jonny [76]4 years ago
5 0

Answer:

That can be re-written:

x^2 + 5x -8 = 0

We use the Quadratic Formula

a=1

b = 5

c = -8

x = [-b +- sq root (b^2 - 4ac) ] / 2a

x = [-5 +- sq root (25 - - 32)] / 2

x1 = [-5 + sq root (57)] / 2

x1 = 1.27491722

x2 = [-5 - sq root (57)] / 2

x2 = -6.2749172176

Find the center of the circle (x-2)^2+(y-8)^2=33
enyata [817]

Answer:

The center is (2,8)

Step-by-step explanation:

The equation of a circle is written as

(x-h)^2+ (y-k)^2 = r^2

where ( h,k) is the center and r is the radius

(x-2)^2+(y-8)^2=33

The center is (2,8) and the radius is sqrt(33)

Given: a quadratic function with vertex (2,3) opening upward .

Find: the given statement is true or false.

Explanation: if parabola has a vertex at (2,3) and opens upward, it has one real solution., (2,3) will be a lowest point. The vertex will be at lowest point, it will be minimum.

that means graph has no one real solution. hence it will never going to intersect. so this statement is false.

Final answer: the given statement is FALSE.

Answer:

  • x² + x + 1 + 2/(x - 1)

Step-by-step explanation:

  • (x³ + 1) / (x - 1) =
  • (x³ - 1 + 2) / (x - 1) =
  • (x³ - 1)/(x - 1) + 2/(x - 1) =
  • (x - 1)(x² + x + 1)/(x - 1) + 2/(x - 1) =
  • x² + x + 1 + 2/(x - 1)
