Answer:
Step-by-step explanation:
4/x + 4/(x²-9) = 3/(x - 3)
4 / x + 4 / [( x - 3) ( x + 3 )] = 3 / ( x - 3 ) / * x ( x - 3 ) ( x + 3 )
Restrictions : x ≠ 0, x ≠ - 3 , x ≠ 3;
4 ( x + 3 ) ( x - 3 ) + 4 x = 3 x ( x + 3 )
4 ( x² - 9 ) + 4 x = 3 x² + 9 x
4 x² - 36 + 4 x - 3 x² - 9 x = 0
x² - 5 x - 36 = 0
x² - 9 x + 4 x - 36 = 0
x ( x - 9 ) + 4 ( x - 9 ) = 0
( x - 9 ) ( x + 4 ) = 0
x - 9 = 0, or : x + 4 = 0
Answer:
x = 9, x = - 4
Answer:
MY friend the anwser is A I hope this will help plz mark me brainliest
Step-by-step explanation:
(20x^2-19x+3)/5x-1
(400x-19x+3)/5x-1
(381x+3)/5x-1
381x/5x-1 + 3/5x-1
(381/5-381) + (3/5x -3)
(76.2-381) + (3/5x -3)
304.8 + 3/5x-3
101.8 +3/5x
That's what I got. I'm not too sure if it helps though.
-2(-x + 3y) - 3(x - 5y)
-2(-x) - 2(3y) - 3(x) + 3(5y)
2x - 6y - 3x + 15y
2x - 3x - 6y + 15y
-x + 9y
Center is (3, -4) and radius is 1
Step-by-step explanation:
- Step 1: Find center and radius of the circle with equation x² + y² - 6x - 8y + 24 = 0
The standard form of the equation of a circle is x² + y² + 2gx +2fy + c = 0, where center is (-g, -f) and radius = √g² + f² - c
By comparing the 2 equations, 2g = -6, 2f = 8 and c = 24
⇒ g = -6/2 = -3
⇒ f = 8/2 = 4
⇒ c = 24
Center = (-g. -f) = (3, -4)
Radius = √g² + f² - c = √3² + (-4)² - 24
= √9 + 16 - 24 = √1 = 1
