What are you trying to do to my brain?
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)
Answer:
Step-by-step explanation:
Solve for x:
4 (6 x + 1) - 3 (4 x + 3) = 43
-3 (4 x + 3) = -12 x - 9:
-12 x - 9 + 4 (6 x + 1) = 43
4 (6 x + 1) = 24 x + 4:
24 x + 4 - 12 x - 9 = 43
Grouping like terms, 24 x - 12 x - 9 + 4 = (24 x - 12 x) + (4 - 9):
(24 x - 12 x) + (4 - 9) = 43
24 x - 12 x = 12 x:
12 x + (4 - 9) = 43
4 - 9 = -5:
12 x + -5 = 43
Add 5 to both sides:
12 x + (5 - 5) = 5 + 43
5 - 5 = 0:
12 x = 43 + 5
43 + 5 = 48:
12 x = 48
Divide both sides of 12 x = 48 by 12:
(12 x)/12 = 48/12
12/12 = 1:
x = 48/12
The gcd of 48 and 12 is 12, so 48/12 = (12×4)/(12×1) = 12/12×4 = 4:
Answer: x = 4
Slope = (11 + 5)/(4 - 2) = 16/2 = 8
y = mx + b
b = y - mx
b = 11 - (8)(4)
b = 11 - 32
b = -21
Equation: y = 8x - 21
Answer : y = 8x - 21
