Find the equation of a line perpendicular to y - 3x = – 8 that passes through the point (3, 2). (answer in slope-intercept form)

So you would plug it into y-y1 = m (x-x1)

so the perpendicular slope would be 1/3

y - 2 = 1/3 (x - 3)

y - 2 =- 1/3(x) - 1/3(-3)

y = 1/3x + 1 + 2

answer = y = -1/3x + 3

Perpendicular means that you will flip and change sign in this case we have -3 when we flip it and change sign we will get 1/3
So,

First we have to find b:

2=1/3(3)+b
2=1+b
1=b

Second you just write your equation:

Y= 1/3x + 1

Hope it help sweetheart!!

In a recent survey, 64 % of the community favored building a police substation in their neighborhood. If 14 citizens are chosen,

kozerog [31]

Answer: 0.1840

Step-by-step explanation:

The binomial probability formula :-

$P(X)=^nC_x\ p^x(1-p)^{n-x}$ , here n is the number total of trials , p is the probability of getting success in each trial and P(x) is the probability of getting success in x trial.

Given : The probability of the community favored building a police substation in their neighborhood = 0.64

If 14 citizens are chosen, then the probability that exactly 8 of them favor the building of the police substation will be :-

$P(8)={14}^C_{8}\ (0.64)^{8}(1-0.64)^{14-8}\\\\=\dfrac{14!}{8!6!}\times(0.64)^8(0.36)^{6}\\\\0.183996740126\approx0.1840$

Hence, the probability that exactly 8 of them favor the building of the police substation = 0.1840

The mountain road was distinctly -------: it twisted

Dima020 [189]

(C) "serpentine"

Serpentine is a winding word. The phrase would read "The mountain road was distinctly serpentine: it twisted back and forth along the contours of the hillside" if this term were added to the text.

The comma denotes that the meaning of the omitted phrase will be clarified in the second clause of the sentence. Because a winding road does actually curve "back and forth," the word "serpentine" matches the text. The answer is not (A).

A panoramic view is one that encompasses the entire surrounding region. (B) is the wrong answer. Precipitous refers to a steep slope. The answer is not (D). The term "circumscribed" describes something that is restrained or encircled by a line. The answer is not (E). Moving backward is referred to as retrograding.

Identify the coordinates of the point (3,-2), translated 5 units left and 6

kap26 [50]

Answer:

(- 2, 4 )

Step-by-step explanation:

A translation of 5 units left means subtract 5 from the original x- coordinate.

A translation of 6 units up means add 6 to the original y- coordinate.

Thus

(3, - 2 ) → (3- 5, - 2 + 6 ) → (- 2, 4 )
