Puppies : Adults = 1 : 4
Total parts = 1 + 4 = 5
5 parts = 100 dogs
1 part = 100 ÷ 5 = 20 dogs
Answer: 20 puppies
First answer is correct because angles DAB and EAD equal 180 degrees (supplementary)
The answer is 42 feet I use substitution and subtract by 8
Answer:
y + 5 = 2(x−4)
Step-by-step explanation:
slope = 2
y = mx + b
-5 = 2(4) + b
-5 = 8 + b
-8 -8
------------------
-13 = b
y = 2x - 13, in other words --> y + 5 = 2(x−4)
So, y + 5 = 2(x − 4) is the equation of the line that passes through (4, -5).
The midpoint formula is:
(point1 + point2)/2
1) (-2 + 12)/2 = 5
2) (-1 +5)/2 = 2
(0+2)/2 = 1
(2,1)
3) Sqrt of (x2-x1)^2 + (y2 - y1)^2
sqrt of (7 -1)^2 + (-7 - 1)^2
sqrt of (6)^2 + (-8)^2
sqrt of 36 + 64
sqrt of 100
10
Hope this helps!
