What is the slope of a line that is perpendicular to the line represented by the equation x – y = 8?

Mathematics
1 answer:
Elza [17]3 years ago
5 0

Answer:

-1

Step-by-step explanation:

Given equation of line is:

x - y = 8

In order to find the slope of other line we have to convert the given equation in standard form

So,

-y = -x + 8

Multiplying the equation with -1

y = x - 8

The co-efficient of x is the slope of the line.

Here the co-efficient is 1 so the slop of line is 1.

We know that the producct of slopes of perpendicular lines is -1.

Let m2 be the slope of the other line then

1 * m2 = -1

m2 = -1

So the slope of line perpendicular to line x-y = 8 will be: -1 ..

In one U.S.​ city, the taxi cost is $2 plus $0.50 per mile. If you are traveling from the​ airport, there is an additional charg
mario62 [17]

Answer:

60 miles

Step-by-step explanation:

the equation for the cost for traveling from the airport can be represented by y= .50x + 2 + 6

where y is the final cost and x is the amount of miles. plug in 38 to y to get 38 = .50× +2 + 6. Solve for x.

38-6 =.50× +2

32 =.50x +2

32-2=.50x

30=.50x

30/.50=x

60=x

therefore, the 60 miles is how far you can go with $38

In a translation, the line segments that connect each point on the preimage to the corresponding point on the image are not only
Marianna [84]
Translation doesn't change the shape, size, or orientation of anything.
It just moves things around.

So the line segments in the image are not only congruent to the ones
in the original figure.  They're also parallel.

After reading 7/9 of a book, 40 pages are left. Find the total number of pages in the book​
dimaraw [331]

Answer:

180 pages

Step-by-step explanation:

let x be the number of pages in the book , then

\frac{7}{9} x + 40 = x ( multiply through by 9 to clear the fraction )

7x + 360 = 9x ( subtract 7x from both sides )

360 = 2x ( divide both sides by 2 )

180 = x

The total number of pages in the book is 180
