What you do is you take the denominator and you divide it into the numerator.

Solve the quadratic equation by completing the square. x^2 - 10x + 18 = 0

serious [3.7K]

Okay so basically, you subtract 18 on both sides since the 18 doesn't work, making the equation
x² - 10x = -18
So then you add (b/2)², which is 25, to both sides, to get
x² - 10x + 25 = 7
After this, you factor.
(x-5)(x-5) = 7
Then you simplify.
(x-5)² = 7
Then you solve for x.
√(x-5)² = √7
x-5 = (+ or -)√7

~ x= 5 (+ or -)√7 ~

Hope this helps!

The diagonals of a quadrilateral QRST intersect at P(2,3). QRST has vertices at Q(3,6) and R(-3,5). What must be the coordinates

Sergio [31]

Answer:

S (1 , 0)

T (7 , 1)

Step-by-step explanation:

If QRST is a parallelogram, P is the mid point of segment QS and segment RT.

Basic formula for mid-point of segment: ((x1+x2)/2 , (y1+y2)/2)

T (x₁ , y₁) S (x₂ , y₂) P (2 , 3) Q (3 , 6) R (-3 , 5)

2 = (x₁ + (-3))/2 x₁ = 7

3 = (y₁ + 5)/2 y₁ = 1

T (7 , 1)

2 = (x₂ + 3))/2 x₂ = 1

3 = (y₂ + 6)/2 y₂ = 0

S (1 , 0)

The reel good Cinema is conducting a mathematical study. In this theater, there are 200 seats. Adult tickets cost $12.50 and a c

denis23 [38]

Considering no discounts for bringing people to the theatre, and a being the number of adults attending the show and b the number of children attending the show then:

$1500 \leqslant 12.5a + 6.5b \leqslant 2500$
