5 0
You have a line:
y=mx+b  (slope-intercepted form)
m=slope of this line.

The slope of a line perpendicular to that given line will be: ´"m´"
m´=-1/m.

For example:
y=8x+3
m=8

The solpe fo a line perpendicular to "y=8x+3" is:
m`=-1/8

Choose the equation that models the following statement: The current, I amps, produced by a battery is inversely proportional to
Anika [276]
By definition we have to:
 V = I * R
 Where,
 V: Voltage.
 I: Current.
 R: Resistance.
 The current, I amps, produced by a battery is inversely proportional to the resistance, R ohms. Clearing I have:
 I = V / R
 rewriting:
 I = V * (1 / R)
 answer:
 The equation that models the statement is:
 I = V * (1 / R)

What is k/5.2 + 81.9= 47.2
weqwewe [10]
Solution for k/5.2+81.9=47.2 equation:
<span>k in (-oo:+oo)

k/5.2+81.9 = 47.2 // - 47.2

k/5.2-47.2+81.9 = 0

0.19230769*k-47.2+81.9 = 0 // - 81.9-47.2

0.19230769*k = -(81.9-47.2) // : 0.19230769

k = (-(81.9-47.2))/0.19230769

k = 5.20000006*(47.2-81.9)

k = 5.20000006*(47.2-81.9)

Always Practice, It makes Perfect! Anyways, I hope I helped... It would be nice if you can answer mine too, But you dont have to! ;) </span><span>brainly.com/question/253764
