I need an explanation for the problem 4v2=-12v-9. I don't understand why it factors into 4v+3 and 4v+3
kirza4 [7]

Answer:

The factors are 2v+3,2v+3.

The factors are not 4v+3,4v+3

Step-by-step explanation:

Equation is 4v^2=-12v-9.

This equation can be written as follows:

4v^2+12v+9=0

Here,

12v=6v+6v

Therefore,

4v^2+6v+6v+9=0\\2v(2v+3)+3(2v+3)=0\\(2v+3)(2v+3)=0

So, the factors are 2v+3,2v+3.

The factors are not 4v+3,4v+3

Simplify.
Kazeer [188]
(1/2)^2 = 1/4
2-2/3 = 6/3 - 2/3 = 4/3

OK so:
(1/2)^2 - 6(2-2/3) = 1/4 - 6(4/3)
= 1/4 - 8
= 1/4 - 32/4
= -31/4

The equation p=100−4t represents the percent p of battery power remaining in an MP3 player after t hours.
fenix001 [56]

Answer:

Step-by-step explanation:

Here time (t) is the independent variable; power (p) is the dependent one.

The graph of p = 100 - 4t is a straight line with slope -4.  100 is the vertical intercept.  Battery power begins at 100 and steadily decreases after that.
