Answer:

y = 20/7

Step-by-step explanation:

( 4 - 5y ) + - (2y - 16) = 0

First, distribute the negative

4 - 5y -2y + 16 = 0

20 -7y = 0

-20 -20

-7y = -20

y = 20/7

Suppose that y varies jointly with w and x and inversely with z and y = 32- when w = 6, x = 20, and z = 3. Write the equation th

natulia [17]

Y directly proportional to WX and inversely to Z.

Y=k(WX)/Z
Where k is the constant of proportionality.
So, the first thing is to find the value of this constant.

k = YZ/WX
= (32×3)/(6×20)
= 96/120
= 0.8
The <span>equation that models the relationship will be;
Y = 0.8(WX/Z)</span>

liberstina [14]

First you put the equation in point slope form- Y-0= 5x - 4
Then add the zero to the 4.
Final answer: y= 5x -4
