Answer:

x = -4/3 or -1.3333333....... (infinite)

Step-by-step explanation:

6x-4=(12x+4)

6x-4+4=12x+4+4

6x = 12x + 4 + 4

6 = 12x + 8

6x - 12x = 12x + 8 - 12x

-6 = 12x + 8 - 12x

-6x = 8

-6x/6 = 8/-6

x = 8/-6

x = -4/3

Answer:

$\sf x = -\dfrac{4}{3}$

Explanation:

Given Expression:

2(3x-2) = (12x+4)

Remove Parenthesis:

2(3x) - 2(2) = 12x + 4

Multiply Integers:

6x - 4 = 12x + 4

Exchange Sides:

12x - 6x = -4 - 4

Simplify:

6x = -8

Divide Both Sides by 6:

x = -8/6 = -4/3

So far, 907 of the 1223 voters have agreed to the new amendment. Based on this data, what is a reasonable estimate of the probab

lesya692 [45]

Answer:

The probability that the next voter does not agree to the new amendment is 0.2584 or 316/1223

Step-by-step explanation:

First we have to calculate the number of voters who did not accept the amendment

For this we have to subtract the number of voters who accepted the new amendment from the total number of voters

1223 - 907 = 316

To calculate the probability that someone will not vote in favor of the amendment we simply have to divide the number of negative votes by the number of total votes

316 / 1223 = 0.2584

The probability that the next voter does not agree to the new amendment is 0.2584

solve the problem related to population growth.A city had a population of 23,900 in 2007 and a population of 25,100 in 2012.(a)

Finger [1]

Solution

To find the exponential growth function, we apply the exponential growth formula which is

$N(t)=a(1+k)^t$

Where

$\begin{gathered} a\text{ is the }initial\text{ population} \\ k\text{ is the growth rate} \\ t\text{ is the number of time intervals} \end{gathered}$

Given that

$\begin{gathered} a=23,900 \\ N(5)=25,100 \\ t=2012-2007=5 \end{gathered}$

Substitute the variables into the exponential growth formula

$\begin{gathered} 25100=23900(1+k)^5 \\ \text{Divide both sides by 23,900} \\ \frac{25100}{23900}=\frac{23900(1+k)^5}{23900} \\ 1.05021=(1+k)^5^{} \\ \sqrt[5]{1.05021}=1+k \\ 1.00984=1+k \\ \text{Collect like terms} \\ k=1.00984-1 \\ k=0.00984 \end{gathered}$

Hence, the exponential growth function is
