Find the parallel and perpendicular slope of a line if linear equation is 7y=20(x-3) Slope (Parallel) is ____ Slope (Perpendicul

yKpoI14uk [10]

Answer:

The parallel line has slope $\frac{20}{7}$

The perpendicular line has slope $-\frac{7}{20}$

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope.

Parallel lines:

Parallel lines have the same slope.

Perpendicular lines:

If two lines are perpendicular, the multiplication of their slopes is -1.

In this question:

We have the following line:

$7y = 20(x-3)$

Placing it in the general format

$7y = 20x - 60$

$y = \frac{20x}{7} - \frac{60}{7}$

So this line has slope $\frac{20}{7}$

Parallel line:

Same slope, so the parallel line has slope $\frac{20}{7}$

Perpendicular line:

Multiplication of the slopes is -1. So

$\frac{20m}{7} = -1$

$20m = -7$

$m = -\frac{7}{20}$

The perpendicular line has slope $-\frac{7}{20}$

The perimeter of a rectangle is 72 m. The width of the rectangle is 16 m. What is the area of the rectangle?

liq [111]

Answer:

320m

Step-by-step explanation

a rectangle has four sides, two pairs of identical sides. So two sides are 16. So that adds up to 32. Perimeter is all sides added together. so it has to add up to 72. 72 minus 32 is 40, so two of the sides have to be 40. Area is length times width, so 16 times 20, which is 320.
