Determine if each relationship is a proportional or nonproportional Explain your reasoning. The problem is, v= 1/10u

Respuesta :

Answer:

yes

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

v-(1/10*u)=0

Simplify

1/10

2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  10  as the denominator :

         v     v • 10

    v =  —  =  ——————

         1       10  

Equivalent fraction: The fraction thus generated looks different but has the same value as the whole

Common denominator: The equivalent fraction and the other fraction involved in the calculation share the same denominator

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators, put the sum or difference over the common denominator then reduce to lowest terms if possible:

v • 10 - (u)              10v - u

——————  =  ———————

     10                        10  

equation at the end of step 2

10v - u

 ————  = 0  

   10  

3.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 10v-u

 ————— • 10 = 0 • 10

  10  

Now, on the left-hand side, the  10  cancels out the denominator, while, on the right-hand side, zero times anything is still zero.

The equation now takes the shape :

  10v-u  = 0

3.2     Solve   10v-u  = 0

we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
