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}

drek231 [11]

Answer:

0.225

Step-by-step explanation:

Total outcomes of choosing 5 out of 18 members = 18C5

Outcomes of choosing 2 out 11 favourers, 3 out of 7 members  =          11C2 & 7C3

Probability = Favourable outcomes / Total outcomes

= ( 11C2 x 7C3 ) / 18C5

<u>[ { 11 ! / 2! 9! } {7 ! / 3! 4! } ] </u>

       [ 18 ! / 5! 13! ]

( 55 x 35 ) /  8568

1925 / 8568

= 0.2246 ≈ 0.225
