Find x when y=5 if y varies inversely as x and x=6 when y =-18
Vera_Pavlovna [14]
It has been given that y varies inversely with x, therefore the equation for this relationship is as follows;
y =\frac{k}{x}\
when y = -18 and x = 6
-18 = k/ 6 ---1)
We need to find x when y = 5
 5 = k/x
when we divide 1)/2), k gets cancelled 

\frac{-18}{5}=  \frac{x}{6}
x = -18*6/5
x = -21.6
when y = 5, then x = -21.6

Study the equation.<br> x² + 6x = - 4
Zinaida [17]

Answer:

x = -3+√5,  -3-√5 (exact roots)

or  x = -0.76, -5.24   to the nearest hundredth.

Step-by-step explanation:

x² + 6x = - 4

Completing the square:

(x + 3)^2 - 9 = -4

(x + 3)^2 = 5

x + 3 = +/-√5

x = - 3 + √5, - 3 - √5
