Write the equation of the line perpendicular to y= 2x +1 that passes through the point (6,2)

Xelga [282]

Answer:

Step-by-step explanation:

Hello:

the equation is : y = ax+b

the slope is a : a×(2) = -1......( perpendicular to a line with a slope of 2 for : y=2x+1)

a =-1/2 y=(-1/2)x+b

the line that passes through (6, 2) : 2 = (-1/2)(6)+b

b = 5

the equation is : y = (-1/2)x+5

The class has n students, and n is an even number. The students are forming teams to work on their homework. Each team has exact

yuradex [85]

Answer:

Distinct ways in which they all can form the teams for the class = n(n-1)

Step-by-step explanation:

Total numbers of students = n (even number)

Number of student in each team = 2

Number of distinct ways are there to form the teams for the class:

$P^{n}_{k}=\frac{n!}{(n-k)!}$

where = n = number of elements = n

k = number of elements choose = 2

$P^{n}_{2}=\frac{n!}{(n-2)!}=\frac{n\times (n-1)\times (n-2)!}{(n-2)!}$

$=n\times (n-1)$

Write an equation that is perpendicular to y=5x−4 and goes through the point (10, -1)

d1i1m1o1n [39]

Answer:

Equation of the perpendicular line is $y=-\frac{1}{5}x+1$

Step-by-step explanation:

Given equation is y = 5x - 4

By comparing this equation with slope-intercept form of the equation,

y = mx + b

Slope of this line $m_{1}=5$

Let the slope of the perpendicular line = $m_{2}$

By the property of perpendicular lines,

$m_{1}\times m_{2}=(-1)$

$5\times m_{2}=(-1)$

$m_{2}=-\frac{1}{5}$

Equation of the perpendicular line passing through a point $(x_{1}, y_{1})$ and slope m is represented by

$y-y_{1}=m(x-x_{1})$

If the given point is (10, -1) and slope 'm'= $-\frac{1}{5}$

$y+1=-\frac{1}{5}(x-10)$

$y=-\frac{1}{5}x+2-1$

$y=-\frac{1}{5}x+1$
