What is the slope of the perpendicular line to 8x - 3y = -9

Mathematics

Answer:

-3/8

Step-by-step explanation:

8x-3y=-9

3y=8x-(-9)

3y=8x+9

y=8/3x+9/3

y=8/3x+3

perpendicular means negative reciprocal of the current slope,

and the negative reciprocal of 8/3 is -3/8.

What is the answer for 5/2 and it is equal to 1/3
Fofino [41]

Answer:

5/2=2.5, while 1/3= aprox 0.333, therefore 5/2 is not equal to 1/3.

Step-by-step explanation:

Here is the long division table for 5/2

 2. 5 0 0

2 5. 0 0 0

− 4      

 1 0    

− 1 0    

   0 0  

 −   0  

     0 0

   −   0

       0

Here is the long division table 1/3 ( to three decimal places)

0. 3 3 3

3 1. 0 0 0

− 0      

 1 0    

−   9    

   1 0  

 −   9  

     1 0

   −   9

       1

An easier way to do 5/2 is to think of 50/2, which is 25, and then add a decimal point, making it 2.5.

An easier way to do 1/3 is to think of it as one third (of one), or 0.333 repeating.
