How do I solve qudratic equations with factions, like this one:<br> <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B3%7D%2
IceJOKER [234]
There are several approaches.

(5/3)x^2 - 5 = 0 has the coefficients a=5/3, b=0 and c = -5.

Thus, the quadratic formula would be appropriate here:

         -0 plus or minus sqrt(0^2 - 4(5/3)(-5) )
x  = -------------------------------------------------------
                                 2(5/3)
         plus or minus sqrt(100/3)
    = ------------------------------------
                         10/3
            3      10
     = ------* ----------- = sqrt(3)    (answer)
          10     sqrt(3)

What is the inverse of f(x)=(4x-3)/7
iragen [17]

Answer:

f(x)^-1 =  \frac{1}{28} x + \frac{3}{4}

Step-by-step explanation:

f(x) = (4x - 3) / 7

y = (4x - 3) / 7

x = (4y - 3) / 7

x / 7 = 4y - 3

x/7 + 3 = 4y

y = \frac{1}{28} x + \frac{3}{4}

Name the algebraic property demonstrated in the example below:
Masja [62]
Answer: Choice D) Commutative Property of Multiplication

-------------------------------------

The commutative property of multiplication states that a*b = b*a. In other words, it doesn't matter how you multiply two numbers. The order isn't important. 

For example, 2*3 = 3*2 = 6

So that's why we're able to do x*y = y*x
Furthermore, 
x*y*z = y*x*z
Only the x and y swap places
