Answer:
D, (-6,-2)
Step-by-step explanation:
the first quadrant of a coordinate plane has the x coordinate being a negative number, and the y coordinate being a positive number
the second quadrant of a coordinate plane has the x and y coordinates being a positive number
the third quadrant of a coordinate plane has the x and y coordinates being a negative number
the fourth quadrant of a coordinate plane has the x coordinate being a positive number, and the y coordinate being a negative number
i have attached a graph showing the quadrants for a visual point of view
Answer:
<em>a</em><em>}</em><em>4</em><em>/</em><em>3</em>
<em>b</em><em>}</em>
<em>c</em><em>}</em><em>-</em><em>1</em><em>/</em><em>4</em>
Step-by-step explanation:
a}4-c/4-(2+b)
putting the values of b and c n its place
4-(-4)/4-(2-4)
4+4/4-(-2)
8/4+2
8/6
4/3 or 1.33
b}IDK SORRY
c} y-x+5+y/4
-1-4+5-1/4
-6+5/4
-1/4
x + 4 = 3x - 8, is assuming D is the midpoint, and therefore ED = DB.
all we know is that D is <u>somewhere</u> in EB.
![\bf E\stackrel{x+4}{\rule[0.35em]{17em}{0.25pt}}D\stackrel{3x-8}{\rule[0.35em]{10em}{0.25pt}}B \\\\\\ EB=ED+DB\implies EB=(x+4)+(3x-8)\implies EB=4x-4](https://tex.z-dn.net/?f=%5Cbf%20E%5Cstackrel%7Bx%2B4%7D%7B%5Crule%5B0.35em%5D%7B17em%7D%7B0.25pt%7D%7DD%5Cstackrel%7B3x-8%7D%7B%5Crule%5B0.35em%5D%7B10em%7D%7B0.25pt%7D%7DB%0A%5C%5C%5C%5C%5C%5C%0AEB%3DED%2BDB%5Cimplies%20EB%3D%28x%2B4%29%2B%283x-8%29%5Cimplies%20EB%3D4x-4)
(4)(-9) + 2 (-1) = - 38
