Answer:

$R = \frac {3ST}{2S + T}$

Step-by-step explanation:

Given the equation;

$\frac {3}{R} - \frac {1}{S} = \frac {2}{T}$

Rearranging the equation, we have;

$\frac {3}{R} = \frac {2}{T} + \frac {1}{S}$

Lowest common multiple (LCM) of S and T is ST.

$\frac {3}{R} = \frac {2S + T}{ST}$

Cross-multiplying, we have;

$3ST = R(2S + T)$

Making R, the subject of formula;

$R = \frac {3ST}{2S + T}$

Answer:

Step-by-step explanation:

To find the y- intercept, let x = 0 in the equation

Given

f(x) = - $\sqrt{5x+2}$ - 1, then

f(0) = - $\sqrt{5(0)+2}$ - 1 = - $\sqrt{2}$ - 1 ← y- intercept,

(0, - $\sqrt{2}$ - 1 ) ← coordinates of y- intercept
