What is an equation of the line that passes through the point (2,−6) and is parallel to the line x−2y=8?
lorasvet [3.4K]

Answer:

y = x/2 - 7

Step-by-step explanation:

First, we need to find the slope of the given equation: x - 2y = 8

Subtract x from both sides

x - 2y = 8

- x        - x

-2y = 8 - x

Divide both sides by -2

-2y/-2 = (8 - x)/-2

y = -4 + x/2

The slope of this equation is 1/2

So the equation of our parallel equation is y = x/2 + b

We have to find b, so plug in the given coordinates

-6 = 2/2 + b

-6 = 1 + b

Subtract 1 from both sides

-6 = 1 + b

- 1    - 1

b = -7

Plug it back into the original equation

y = x/2 - 7

This figure consists of a rectangle and a quarter circle.
poizon [28]

The perimeter of the figure is 50.56 cm.

Solution:

Radius of the quarter of a circle = 8 cm

Perimeter of the quarter circle = \frac{1}{4} 2\pi r

                                                  $=\frac{1}{4} \times 2  \times 3.14  \times 8

                                                  = 12.56 cm

In figure, one side of the quarter circle is merged with rectangle, so remove one radius from the perimeter of the quarter circle.

Perimeter of the given quarter circle = 12.56 cm – one radius

                                                             = 12.56 cm – 8 cm

                                                             = 4.56 cm

Perimeter of the rectangle given = (17 – 8) cm + 10 cm + 17 cm + 10 cm

                                                       = 9 cm + 10 cm + 17 cm + 10 cm

                                                       = 46 cm

Perimeter of the given figure = 4.56 cm + 46 cm

                                                = 50.56 cm

Hence the perimeter of the figure is 50.56 cm.
