No because for example (4-2)(x) is not the same as (2-4)(x). It would be negative

Answer: 1. x= -12 2. x= 12

Step-by-step explanation:

1. 5(+3)=−45

5x+15−15=−45−15

5x= -60

5x/5 = -60/5

x = -60/5

x= -12

2. 1x/2−4=2

x/2 -4=22−4+4=2+4

/2=6

2⋅2=2⋅6

x=2⋅6

x= 12

Pleasee Help!!! v2=?

<h3>Given :</h3>

$\sf l = p(v_{2} - v_{1})$

$\tt v_{2} = ?$

<h3>Solution :</h3>

$\sf \dashrightarrow l = p(v_{2} - v_{1})$

$\sf \dashrightarrow \dfrac{l}{p} = v_{2} - v_{1}$

$\sf \dashrightarrow \dfrac{l}{p} + v_{1} = v_{2}$

$\sf \dashrightarrow v_{2} = \dfrac{l}{p} + v_{1}$

$\large \underline{\boxed{\bf{v_{2} = \dfrac{l}{p} + v_{1}}}}$

Hence, value of $\sf v_{2} = \dfrac{l}{p} + v_{1}$

The population of a small town in central Florida has shown a linear decline in the years 2001-2012. In 2001 the population was

earnstyle [38]

Answer:

Step-by-step explanation:

First of all, to keep our numbers manageable, we are going to let year 2001 = 0 so year 2012 = 11. The coordinates that result from these years/population numbers are (0, 22200) and (11, 13950). Since this linear, we can plug those 2 coordinate pairs into the slope equation to find the rate at which the population is decreasing in people per year:

$m=\frac{13950-22200}{11-0}=\frac{-8250}{11}=-750\frac{people}{year}$ That means that the town is losing people at the rate of 750 per year. We can use that slop along with one of the coordinate points to write the linear equation representing this situation:
