Answer:

x=17

Step-by-step explanation:

LM=3x+18

LO=2LM=2(3x+18)=6x+36

LO=9x-15

Set them equal to each other.

6x+36=9x-15

-3x+36=15

-3x=-51

x=17

Change the equation of the circle x^2+14x+y^2-10y=14x 2 + 14 x + y 2 − 10 y = 14 into center-radius form of a circle.
jonny [76]

Answer:

The answer to your question is      (x + 7)² + (y - 5)² = 88

Step-by-step explanation:

Equation

                     x²  +  14x  +  y²  - 10y   =  14

Complete perfect trinomial squares

                     x² + 14x + (7)² + y² - 10y + (5)² = 14 + (7)² + (5)²

Simplify

                     x² + 14x + (7)² + y² - 10y + (5)² = 14 + 49 + 25

                     x² + 14x + (7)² + y² - 10y + (5)² = 88

Factor

                     (x + 7)² + (y - 5)² = 88   This is the equation in the form

                     center-radius

Which expression is equivalent to −19y+13 ?
Vikki [24]
The first thing you should do in this case is to write the expression correctly:
 - (1/9) y + (1/3)
 Now, we take out common factor (1/9) obtaining:
 1/9 (-y + 3)
 Let's check:
 1/9 (-y + 3)
 -1/9y + 3/9
 -1/9y + 1/3
 OK
  Answer: 
 An expression equivalent is: 
 1/9 (-y + 3)
