Answer:
y = 3
Step-by-step explanation:
Both y = 3 and y = 0 have zero slopes. Therefore, they are parallel.
Answer:
addition
Step-by-step explanation:
32(d/2 - 5) = 224
divide both side by 32
d/2 - 5 = 224/32
d/4 - 5 = 7
multiply both sides by 4
d - 20 = 28
lastly, add 20 to both sides
d = 28 + 20
d = 48
therefore, the last step is addition
Answer: hello your question is incomplete below is the complete question
The Two vectors; A = 5i + 6j +7k and B = 3i -8j +2k.
answer;
angle = 102°
Step-by-step explanation:
multiplying the vectors
A.B = |A| * |B|* cosθ
hence : Cosθ = (Ai*Bi )+ (Aj*Bj) + ( Ak*Bk/ (√A^2 *√B^2 )
= 15 - 48 + 14 /(√25+26+29) * (√9+64+4)
= -0.206448454
θ = cos^-1 ( -0.206448454) = 101.9° ≈ 102°

Let
Jill = J
Beth = B
Meg = M
Sounds like Beth is the youngest.
J = M - 2
B = 1/2 M
Explanation
B = 1/2 M. This means that Beth is 1/2 as old as Meg.
J = M - 2 This means that Jill is 2 years younger than Meg.

I don't think you can go to three statements. You need one more statement than you've given us.
