Two-thirds of a number increased by five is the same as negative two-sixths of a number increased by fourteen.

  9

Step-by-step explanation:

Assuming both numbers are the same, we can use n to represent it.

  2/3n +5 = -2/6n +14

Adding 1/3n-5 gives ...

  n = 9

The number is 9.

Check

  2/3n = 2/3·9 = 6

  -2/6n = -2/6·9 = -3

  6 +5 = -3 +14 . . . . . . true

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
