15PTS PLEASE HELP ASAP! (dont write random answers pls)

Whats the fraction decimal and percent for 15 out of 9

creativ13 [48]

1 2/3, 1.66, 166.66%

btw, put a forever hat above the last 6's in 1.66 and 166.66

a forever hat is just a horizontal line above a number to indicate it goes on forever.

The points(0,2) and (4,-10) lie on the same line and the points (-5,-3) and (2,11) lie on another line. Determine by graphing wh

joja [24]

You are asked to do this problem by graphing, which would be hard to do over the Internet unless you can do your drawing on paper and share the resulting image by uploading it to Brainly.

If this were homework or a test, you'd get full credit only if you follow the directions given.

If The points(0,2) and (4,-10) lie on the same line, their slope is m = (2+10)/(-4), or m =-3. Thus, the equation of this line is y-2 = -3x, or y = -3x + 2.

If points (-5,-3) and (2,11) lie on another line, the slope of this line is:

m = 14/7 = 2. Thus, the equation of the line is y-11 = 2(x-2), or y = 11+2x -4, or y = 2x + 7.

Where do the 2 lines intersect? Set the 2 equations equal to one another and solve for x:

y = -3x + 2 = y = 2x + 7. Then 5x = 5, and x=1.

Subst. 1 for x in y = 2x + 7, we get y = 2(1) + 7 = 9.

That results in the point of intersection (2,9).

Doing this problem by graphing, on a calculator, produces a different result: (-1,5), which matches D.

I'd suggest you find and graph both lines yourself to verify this. If you want, see whether you can find the mistake in my calculations.

The perimeter of a rectangle is 150 cm. the length is 4 cm greater than the width find the width and length

Fudgin [204]

Let's call the width of our rectangle $w$ and the length $l$ . We can say $l = w + 4$ , since the length is equal to 4 cm greater than the width.

Also remember that the perimeter of a rectangle is the sum of two times the width and two times the length, or $P = 2l + 2w$ . To solve this problem, we can substitute in the information we know, as shown below:
