Answer:
We cannot have a single point of solution
Step-by-step explanation:
When the boundary lines are parallel, we can have no solution, or infinite solutions. We cannot have a single point of solution
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°
Answer:
Number = -1/2
Step-by-step explanation:
Let the number = x
Now
According to given conditions:
8x + 6 = 2
Subtracting 6 from both sides we get:
8x + 6 - 6 = 2 - 6
8x = -4
Dividing both sides by 8 we get:
x = -4/8
Reducing to lowest form:
x = -1/2
Proof:
8(-1/2) + 6 =2
-8/2 +6 =2
-4 + 6 =2
2 = 2
Hence proved
I hope it will help you !
7/10 = 0.70. They are equal.
