slamgirl [31]

Answer:

y=\frac{1}{5}x+\frac{12}{5}

Step-by-step explanation:

<u><em>Complete Question:</em></u> What is the equation of line that is parallel to the line y=\frac{1}{5}+4 and passes through (-2,2).

Let\ the\ equation\ of\ line\ is\ y=mx+c\\\\Since\ it\ is\ parallel\ to\ the\ line\ y=\frac{1}{5}x+4,\ the\ slope\ of\ both\ the\ lines\ will\ be\ same.\\\\Slope\ of\ y=\frac{1}{5}x+4\ is=\frac{1}{5}\\\\m=\frac{1}{5}\\\\Equation: y=\frac{1}{5}x+c\\\\It\ passes\ through\ (-2,2),\ This\ point\ will\ satisfy\ the\ equation.\\\\2=\frac{1}{5}\times (-2)+c\\\\c=2+\frac{2}{5}\\\\c=\frac{12}{5}\\\\The\ Equation\ is: y=\frac{1}{5}x+\frac{12}{5}

You decide to give 18 of your card collection to your little brother. How much of your collection do you have left?
emmainna [20.7K]

The equation would be

x - 18 = collection left

X = how much was your collection before you gave your brother 13 cards

Since we don't know how big was your collection before, this would be the equation to solve it.

In an electrical circuit ,the voltage across a resistor is directly proportional to the current running through the resitor.If a
Lerok [7]

Answer: The voltage across an identical resistor = 60 Volts

Step-by-step explanation:

Step 1

Given  that voltage across the resistor is directly proportional to the current running through the resitor.

 Mathematically, it would be represented as

Voltage  ∝  Current

Introducing the constant of proportionality,  k which represents the Resistor as it is constant.

we have that

Voltage  = K  x  Current

When current = 12 amps and voltage = 480v, the constant of proportionality  K

480 = k x 12

k = 480/12

k= 40

Step 2 ,

when current = 1.5 amps

 Voltage = ?

Using our equation that

Voltage  = K  x  Current

Voltage = 40 x 1.5

Voltage = 60 Volts
