Answer:

The first first in solving for x is do the distributive property to the left and right of the eqaution. Distribute 2 with 6x and 6. Distribute 3 with x and -4.

Step-by-step explanation:

PEMDAS states that you do things in the parenthesis first.

In 2000, the population of a county was 25,300,987. The population decreased at a rate of 2% each year. What was the population

EastWind [94]

Answer: In 2008 the population was 21,525,144

Step-by-step explanation:

You need to use the following formula for Exponential decay:

$P=P_0(1-r)^t$

Where $P_0$ is the initial population in the year 0, $r$ is the rate of decay and $t$ is the time.

In this case, you can identify that:

$P_0=25,300,987\\\\r=2\%\\\\t=8$

Therefore, substituting these values into the formula for Exponential decay, you get:

$P=P_0(1-r)^t\\\\P=(25,300,987)(1-\frac{2}{100})^8\\\\P=21,525,144$

Then, in 2008 the population was 21,525,144

What is the slope of this line

Rashid [163]

Answer:

Slope = 2/3

Step-by-step explanation:

Slope = Change over y (rise) over change over x (run)

Pick two dot points on the line

Count how many units over they are until you get to the next dot, then count how many units up until you reach the next dot

Remember: Y runs vertically, X runs horizontally

Put the unit number that ran vertically on the top, then put the unit number that runs horizontally on the bottom

If needed simplify

The slope is 2/3

Can u solve this problem in show your work

aksik [14]

Hey there!

We can solve this problem by doing PEMDAS, which lists:

$Parentheses \\ Exponents \\ Multiplication \\ Division \\ Addition \\ Subtraction$

We have in this equation

$Parentheses \\ Exponents \\ Dvision$

Let's sp;ve this equation now!

Parentheses ↓

$(6 -3) = 3$

Exponents ↓

$3^2 = 9$

Division ↓

$\frac{36}{9} = 9$

Okay now , I show you the steps so it can be easier to solve!

$\frac{36}{(6-3)^2} \\ \\ 6-3 = 3 \\ \\ \frac{36}{3^2} \\ \\ 3^2 = 9 \\ \\ \frac{36}{9} \\ \\ \\ \\ Answer: 4$

Good luck on your assignment and enjoy your day!
