Answer:
(3x-1)(2x+1)
Step-by-step explanation:
1-6x^2-x=0
-6x^2-x+1=0
6x^2+x-1=0
6x^2+(3-2)x-1=0
6x^2+3x-2x-1=0
3x(2x+1)-1(2x+1)=0
(3x-1)(2x+1)=0
So the factor is (3x-1)(2x+1)
I think the correct answer is D), I’m sorry if it’s wrong
Decibel is directly proportional to number of cars passing the point. That is,
69 db ----- 139 cars
x db ----- 17 cars
x = number of cars passing the point per minute on a weekend.
Then,
x= (69*17)/139 = 8.43 db ≈ 8 db
Answer:
x = -27
Step-by-step explanation:
4x+27=3x
Subtract 3x from both sides of the equation.
==> 4x + 27 -3x = 3x - 3x
==> 4x - 3x + 27 = 0
==> 1x + 27 = 0
Subtract 27 from both sides,
==> x + 27 - 27 = 0 - 27
==> x = -27
