Solve for x: 2x – y = (3/4)x + 6.
Artyom0805 [142]

Answer:

B

Step-by-step explanation:

2x – y = (3/4)x + 6.

or, 2x - (3/4)x = y + 6.

or, (8x -3x)/4 = y + 6.

or, 5x/4 = y + 6.

or, 5x = 4(y + 6).

or, 5x = 4y + 24.

or, x = (4y + 24)/5.

Therefore, x = 4(y + 6)/5.

Factor 60x2 – 155x + 100 completely
gtnhenbr [62]

Answer:

hello :

60x² – 155x + 100 = 5 ( 12 x² - 31 x + 20 )

delta of ( 12x² - 31 x + 20 ) is b² - 4ac   when : a = 12    b = -31   c = 20

delta = ( - 31 )² - 4(12)(20) = 961 - 960 = 1

x1 = (31-1)/24 = 30/24 = 5/4

x2 =  (31+1)/24 = 32/24 = 4/3

Factor 60x2 – 155x + 100 = 5 (12(x -5/4)(x- 4/3)) = 60 (x -5/4)(x- 4/3)
