Answer:

The slope of a line perpendicular to this line would be 2/7 and the slope of a line parallel to this line would be -7/2.

Step-by-step explanation:

In order to find these, we first need to solve the equation for y.

7x + 2y = 1

2y = -7x + 1

y = -7/2x + 1

Now we can see the original slope is -7/2 due to it being the coefficient of x. We know parallel lines have the same slope, so the parallel slope is simple -7/2.

We also know perpendicular slopes have opposite and reciprocal slopes. So we take the -7/2 and change the sign (giving us 7/2). Then we flip it to get 2/7.

Each side of a rhombus is 20 cm long and one of its diagonals is 24 cm in length, find the area of ​​this rhombus?
vodomira [7]

Answer:

AB = 20 CM

OA = 1

__ × 24 cm

2

= 12 cm

AOB = 90 °

OB² == AB² - OA ²

( {20}^{2} ) - ( {12}^{2} ) \\  = 400 - 144 \\  = 256 \\

ob \:  =  \sqrt{256}  = 16 \\ bd \:  = 2 \times ob \\  = 2 \times 16 \\  = 32cm \:  \\

AREA OF ABCD IS

\frac{1}{2 }  \times ac \times bd \\  =  \frac{1}{2}  \times 24 \times 32 \\ 384cm
