Answer:

Step-by-step explanation:

you only use opposite of order of opperations with algebra

so you would do the 12/4 first then add 8. if this was an algebaic equation add 8 first. but this is a normal equation

A population of 120,000 grows 3% per year for 15 years, how much will the population be after 15 years?

Wewaii [24]

270,000 is the answer because you have three over 100 so you do 100 divided by three which give you 0.15 then you do 120,000 times 0.15 to find out how much it grows per year to get 18,000 then you multiply 18’000 by 15 and get 270’000

Point a is at (-7,-7) and m is at (-6,-1) what are the coordinates of point b

AlekseyPX

Answer:

The coordinates of point b are (-5,5).

Step-by-step explanation:

Given:

Point a is at (-7,-7) and m is at (-6,-1).

So, to find the coordinates of point b.

Let a (-7,-7) be $(x_{1},y_{1})$ , m (-6,-1) and b $(x_{2} ,y_{2})$ .

Now, putting the formula to get the coordinates:

$m=\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2}$

⇒ $(-6,-1)=\frac{-7+x_{2}}{2} , \frac{-7+y_{2}}{2}$

So, here we will make two equations to find the value of $x_{2} andy_{2}$ :

$-6=\frac{-7+x_{2}}{2}$

multiplying both sides by 2

⇒ $-12=-7+x_{2}$

⇒ $-5=x_{2}$

And, now same method for getting the value of $y_{2}$ .

$-1=\frac{-7+y_{2}}{2}$

multiplying both sides by 2

⇒ $-2=-7+y_{2}$

⇒ $5=y_{2}$ .

The value of $(x_{2} ,y_{2})$ = $(-5,5)$ .

Therefore, the coordinates of point b are (-5,5).
