Write the equation of the line in point-slope form of the given point and slope. This is an essay style question. If you hit the

svp [43]

Answer:

Step-by-step explanation:

The point-slope form of the equation will be expressed as;

y - y0 = m(x-x0) where;

m is the slope

(x0, y0) is the point on the line

Given

Slope m = 3/7

Point (x0, y0) = (7, -2)

Substitute into the equation;

y - y0 = m(x-x0)

y - (-2) = 3/7 (x - 7)

<em>Hence the equation in point-slope form is y + 2 = 3/7(x-7)</em>

Consider a refrigerator that consumes 320 W of elec- tric power when it is running. If the refrigerator runs only one quarter of

irinina [24]

Answer: The refrigerator cost in this month is $4.5 approximately.

Step-by-step explanation:

Since we have given that

Amount of watt of electric power = 320 W

Number of days = 30

Unit cost of electricity = $0.13/Kwh

Hold factor = $\dfrac{1}{4}$

Number of hours in a month = 24

So, the refrigerator cost in this month would be

$0.13\times 0.32\times \dfrac{1}{4}\times 30\times 24\\\\=\$7.488$

Hence, the refrigerator cost in this month is $4.5 approximately.
