Answer:
a= 52
Step-by-step explanation:
82 + (x+60) + (x+54) = 180
82 + 2x + 114 = 180
2x + 196 = 180
2x = -16
x = -8
plug in -8 in x +60
-8 + 60 = 52
a = 52
The answer would be -37.5
THE ANSWER IS: y = -x+9
y=mx+b
m=slope=(y2-y1)/(x2-x1)
use the points (0,9) and (9,0)
(0-9)/(9-0) = -9/9 = -1
so m=-1
b is the y-intercept which is where x=0
the line crosses the y axis at y=9
so b=9
plugging in m and b into y=mx+b,
you get y=-x+9
It’s C.
Just complete the rectangle. You’ll get it.
Answer:
(3,3)
Step-by-step explanation:
Use the midpoint formula to find your answer. The formula is 
.
If that equation looks funny then let me explain. You need to add 10 and -4 together, then divide it by 2. You also need to add -3 and -9, then divide that by 2.
