A store sells mugs. Each mug costs the same amount. During a sale, the store reduces the price of each mug by $1.75. Wen spends

Ostrovityanka [42]

Answer:

$7.39

Step-by-step explanation:

Let the initial price be x

<u>Then the reduced price is </u>

x - 1.75

<u>If 5 mugs cost $28.20, we have equation:</u>

(x - 1.75)*5 = 28.20
x - 1.75 = 28.20/5
x - 1.75 = 5.64
x = 1.75 + 5.64
x = 7.39

Initial price for 1 mug was $7.39

AleksandrR [38]

Answer:

R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]

Step-by-step explanation:

Squaring both sides of equation:

I^2 = (ER)^2/(R^2 + (WL)^2)

<=>(ER)^2 = (I^2)*(R^2 + (WL)^2)

<=>(ER)^2 - (IR)^2 = (IWL)^2

<=> R^2(E^2 - I^2) = (IWL)^2

<=> R^2 = (IWL)^2/(E^2 - I^2)

<=> R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]

Hope this helps!

Identify the equations as parallel lines, perpendicular lines, or neither.

Alex

Answer:

B. Parallel

Step-by-step explanation:

Equation 1 simplified: y = 3x+7

Equation 2 simplified: y = -x/3-3

The slopes are completely different, ruling out the possibility of the lines being parallel.

But we also see the slopes of the equations are opposite and negative to each other. Making the lines perpendicular.
