x/x^2-9 + 1/x-3 = 1/4x-12

x/(x+3)(x-3)+1/(x-3)=1/4(x-3)

LCD: 4(x+3)(x-3)

4x+4(x+3)=(x+3)

4x+4x+12=x+3

7x=-9

x=-9/7

A circle is centered at the point (5, -4) and passes through the point (-3, 2).
harina [27]

Answer:

The answer to your question is:

             (x - 5)² + (y + 4)² = 10²     or         (x - 5)² + (y + 4)² = 100

Step-by-step explanation:

Data

Center (5, - 4)

Point ( -3 , 2)

Formula

d = √ ((x2- x1)² + (y2 - y1)²)

(x - h)² + (y - k)² = r²

Process

Radius

d = √ ((-3 - 5)² + (2 + 4)²)

d = √ ((-8)² + (6)²)

d = √ 64 + 36

d = √100

d = 10 units

Circle

                           (x - 5)² + (y + 4)² = 10²

                             (x - 5)² + (y + 4)² = 100

A spinner and 4 cards are shown below:
yan [13]

Answer: 1 over 20

Step-by-step explanation: If the spinner has 5 parts to it at purple is one of those parts then the spinner has a 1/5 chance of it landing there.

If there are 4 cards and 1 of them are pink then there is a 1/4 chance of picking pink(if done randomly)

So if we mutiply 1/4 and 1/5, we get 1/20

That is how I arrived at my answer of 1 over 20

  Pink 1/8 = 3/24

  Yellow 3/8 = 9/24

6) 11/2x - 2(3x - 1/8)       Distribute the -2

   11/2x - 6x + 1/4           Combine like terms

-1/2x + 1/4

7) z ≥ 0

z is greater than or equal to 0
