Step-by-step explanation:

<h3>Given</h3>
  • Side 1: 3x² - 2x - 1
  • Side 2: 9x + 2x² - 3
  • Perimeter:  5x³ + 4x² - x - 3
<h3>Part A</h3>

Sum of side lengths 1 and 2

  • 3x² - 2x - 1 + 9x + 2x² - 3 =
  • 5x² + 7x - 4
<h3>Part B</h3>

The perimeter is the sum of all three sides.

<u>The length of the third side is</u>

  • P - (side 1 + side 2) =
  • 5x³ + 4x² - x - 3 - (5x² + 7x - 4) =
  • 5x³ + 4x² - x - 3 - 5x² - 7x + 4 =
  • 5x³ - x² - 8x + 1

Part A - addition

Part B - subtraction

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.

3.14=7x-2y
eimsori [14]

3.14=7x-2y

move 7x to the other side

sign changes from +7x to -7x

3.14-7x=7x-7x-2y

3.14-7x=-2y

Divide both sides by -2

3.14/-2-7x/-2=-2y/-2

3.14/-2=-1.57

-7x/-2=7x/2

Answer:

y=-1.57+7x/2
