An electric company charges an initial monthly fee for service and a fixed rate per kilowatt-hours (kWh) used. This table shows
Vlada [557]

<em>Here we are required to determine the initial monthly fee charged by the electric company.</em>

The initial fee charged by the electric company is; C = $10

To solve this, we need to evaluate the slope and intercepts of the equation of the straight line graph of the relation.

y = mx + c.

  • where m = slope of the relation.

  • and c = <em>intercept = the initial fee charged by the electric company</em>.

  • y = <em>Monthly charge at each time</em>.

  • x = Usage

To find the slope;

  • m = (y2 - y1)/(X2 - x1)

  • m = (28 -22)/(150 - 100)

  • m = 6/50

  • m = 0.12.

By substituting m into the equation y = mx + c, alongside a pair of values of usage and monthly charge, we can obtain the intercept, c (i.e the initial fee charged).

Therefore, m = 0.12 , y = 82 and X = 600;

we then have;

  • 82 = 0.12(600) + c.

  • C = 82 -72

  • C = $10.

Therefore, the initial fee charged by the electric company is; C = $10.

What is the answer to this equation 50X6-?=265/ I assume it is poitive 35. Is that correct?
lys-0071 [83]
Well, 50*6-x=265, so 300-x=265, so x=300-265=35

Evaluate 2x for each value of x. Write your answers in simplest form. Show your work!
Liono4ka [1.6K]

1. 1/2

2.2/3

3. 1

4. 1/3

5. 2/7

6. 1/4

7. 4/3

8. 3/2

<h3>How to evaluate the value</h3>

To find 2x of the vale of x, we have to multiply the value of 'x' by 2

1. x = 1/4

2x = 2 * \frac{1}{4} ⇒ \frac{2}{4} ⇒\frac{1}{2}

2. x = 1/3

2x = 2 * \frac{1}{3} ⇒\frac{2}{3}

3. x = 1/2

2x = 2* \frac{1}{2} ⇒ \frac{2}{2} ⇒ 1

4. x= 1/6

2x = 2* \frac{1}{6} ⇒ \frac{2}{6} ⇒ \frac{1}{3}

5. x = 1/ 7

2x = 2 * \frac{1}{7} ⇒ \frac{2}{7}

6. x = 1/8

2x = 2 * \frac{1}{8} ⇒ \frac{2}{8} ⇒ \frac{1}{4}

7. x = 2/3

2x = 2 * \frac{2}{3} ⇒ \frac{4}{3}

8. x = 3/4

2x = 2 * \frac{3}{4} ⇒ \frac{6}{4} ⇒ \frac{3}{2}
