if point A is located at (0,-8) and B is located at (4,-5)
We use distance formula
(0,-8) is (x1, y1) and (4,-5) is (x2,y2)
x1 = 0 , y1= -8 , x2= 4 and y2= -5
so d= 5
The distance between 2 points is 5
Answer:
yes (also the c.o.p would be 5)
Step-by-step explanation:
if you model this on a graph, it comes out proportional because its starts from the origin, and its a straight line with no curves.
Answer:
5x+9 = 109
3x+11 =71
Step-by-step explanation:
A linear pair adds to 180
5x+9 + 3x+11 =180
Combine like terms
8x + 20 =180
Subtract 20 from each side
8x +20-20 = 180-20
8x = 160
Divide each side by 8
8x/8 = 160/8
x=20
5x+9 = 5*20+9 = 100+9 = 109
3x+11 = 3*20+11 = 60+11=71
Answer:
-1.6
Step-by-step explanation:
4x +8y=0
y=0.8 ⇒
- 4x+8*0.8=0
- 4x+6.4=0
- 4x=-6.4
- x= -6.4/4
- x= -1.6
