Answer:

y + 8 = 6(x + 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = 6 and (a, b) = (- 1, - 8), hence

y - (- 8) = 6(x - (- 1)), that is

y + 8 = 6(x + 1)

<u>ANSWER</u>

y + 8=6(x + 1)

<u>EXPLANATION</u>

The point-slope form of an equation is given by the formula:

y-y_1=m(x-x_1)

Where

(x_1,y_1)

is a point on this line and

m

is the slope of the line.

From the question, the line has slope 6 and passes through (-1,-8).

This means that

x_1=-1

y_1=-8

and

m = 6

We substitute these values into the point-slope formula to get:

y- - 8=6(x- - 1)

We simplify to get:

y + 8=6(x + 1)

: A personal computer manufacturer buys 36% of its chips from Japan and the rest from the United St...
meriva

Answer: 0.9862

Step-by-step explanation:

Given : The probability that the chips belongs to Japan: P(J)= 0.36

The probability that the chips belongs to United States : P(U)= 1-0.36=0.64

The proportion of Japanese chips are defective : P(D|J)=0.017

The proportion of American chips are defective : P(D|U)=0.012

Using law of total probability , we have

P(D)=P(D|J)\times P(J)+P(D|U)\times P(U)\\\\\Rightarrow\ P(D)=0.017\times0.36+0.012\times0.64=0.0138

Thus , the probability that chip is defective = 0.0138

Then , the probability that a chip is defect-free=1-0.0138=0.9862

How to solve -18=6y+6(1+3y)
slamgirl [31]

Answer:-1

Step-by-step explanation:

I rewrote it so it looks like this:

6y+6(1+3y)=-18

6y+6(1)+6(3y)=-18

6y+6+18y=-18

24y+6=-18

     <u> -6   -6</u>

<u>24y</u>=<u>-24</u>

24      24

y=-1

27x+5+15x-2 what is the degree angle
Zielflug [23.3K]
The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year.[5] Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day
