answer:

the number is one

work:

let's analyze the question.

15 times a number is..

so, right away we have 15n.

.... decreased by eight...

we are subtracting 8, so 15n - 8

...the result is 17.

so, 15n - 8 will equal 17.

Find the number.

now, we solve for n.

15n - 8 = 17 (add 8 to both sides)

15n = 15 (divide both sides by 15)

n = 1

so, the number is one. hope this helps, have a great day!

The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function?
gogolik [260]

Answer:  If you plot a point in the y-axis at -6, you can plot two more points by using the slope "rise over run" Then draw a line connecting the points.

The coordinate of the y intercept is (0.-6)  To find the first x values of the first 2 coordinates, add 1 then 2 to 0. To find the y values, add 2 then 4 to the -6

Step-by-step explanation:

From -6 go up 2 over 1 and plot at (1, -4 )  then up 2 over 1 again to (2, -2)

The x- intercept will be at  (3,0)

Eric leans a ladder against the roof of his house so that the ladder forms a 2004-04-02-01-00_files/i0260000.jpg angle with the
Flauer [41]
A right angled triangle can be formed from the given scenario as shown below in the figure:

We have a perpendicular(opposite side), the measure of angle and we are interested in finding the hypotenuse.

sine of the angle relates its perpendicular side to hypotenuse as:

sin(x) = perpendicular/hypotenuse

⇒

Hypotenuse = Perpendicular/sin(x) = 13/sin(70) = 13.8 feet

This means, the length of the ladder is 13.8 feet, rounded to nearest tenth.
