to the risk of sounding redundant.

well, let's bear in mind that the LCD for all three fractions will just be "xyz", so then let's multiply both sides by that LCD in order to do away with the denominators and then solve for "z".

\bf \cfrac{2}{x}=\cfrac{3}{y}+\cfrac{1}{z}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{xyz}}{xyz\left( \cfrac{2}{x} \right)=xyz\left( \cfrac{3}{y}+\cfrac{1}{z} \right)}\implies 2yz=3xz+xy \\\\\\ 2yz-3xz=xy\implies \stackrel{\textit{common factor}}{z(2y-3x)}=xy\implies z=\cfrac{xy}{2y-3x}

Find the equation of the line using the exact numbers
Anit [1.1K]

Answer:

y = -0.25x - 6

Step-by-step explanation:

You can either just read off the slope m = -0.25 and the intersection with the vertical n = -6 or you form a system of equations from points you choose on the graph. For example:

(0,-6);(4,-7)

The general equation for a line:

y = m*x + n

The two points on the graph form a system of two equations:

1. -6 = m*0 + n

2. -7 = m*4 + n

You can read off n right away fro equation 1:

n = -6

Plugging n into equation 2:

-7 = m*4 - 6 => -1 = m*4 => m = -1/4
