Answer:
Step-by-step explanation:
<u>The vertices are:</u>
- K(-12,2), L(-7,12), J(3,-10)
<u>Find the sides using distance formula:</u>
- KL =
≈ 11.18 - LJ =
≈ 24.17 - KJ =
≈ 19.21
<u>Find perimeter:</u>
- P = KL + LJ + KJ
- P = 11.18 + 24.17 + 19.21 = 54.56 units
Answer:
H=81
Step-by-step explanation:
If 9=h/9 you multiply both sides by 9 to get h by itself, and end up with h=81.
Answer:
Q1) D
Q2) C
Step-by-step explanation:
Q1)
y ∝ x
y = kx
Let x=-1,y=2
2 = k(-1)
k = -2
Q2)
directly (y=kx)
Let x=2,y=4
4 = k(2)
k = 2
y = 2x
inverse (y = k/x)
Let x=2,y = 4
4 = k/2
k = 8
xy = 8
Answer:
(-2+4)/2
= 1
(-4-8)/2
= -6
(1,-6) is the midpoint of the line
