What is the slope of the line 3 + 4x = 2y - 9

Hello! 

Ok so ideally we would like to see this in y=mx+b form. But it will take some algebreic skills to ninja our way through this. 

I'll show my steps so you can follow, 

3+4x = 2y - 9 (original equation) 

Next we just add 9 to both sides, 

12 + 4x = 2y, now we can divide both sides by 2,

y=2x+6 as our final equation. This is in y=mx+b form, thus the slope of our line is 2 because the 2 is sitting in the m space of the equation. If you  still dont understand linear stuff, I'd google slope-intercept form 

Hope this helped!

2 times 10^4 means 2 with 4 zeroes after it or 20000
4 times 10^6=4 with 6 zeros after it or 400000

compare

20000 and 4000000
we can see that 4000000 is 200 times of 20000
therefor the answer is C

we can also do
(4 times 10^6)/(2 times 10^4)=4/2 times (10^6)/(10^4)=2 times 10^2=200


answer is C

What is the area of a rectangle with side lengths 2/5 feet and 4/6 feet?
kotegsom [21]

Answer:

\frac{4}{15}  (4/15)

Step-by-step explanation:

\frac{4}{6}=\frac{2}{3}

\frac{2}{5}*\frac{2}{3};

1- Multiply the numerators:

2*2=4

2- Multiply the denominators:

5*3=15

3- Thus:

\frac{2}{5}*\frac{2}{3}= \frac{4}{15}

Hope this helps ;)
