Rewrite the system of equations in matrix form.
This system has a unique solution 
so long as the inverse of the coefficient matrix 
exists. This is the case if the determinant is not zero.
We have
so the inverse, and hence a unique solution to the system of equations, exists as long as m ≠ -4.
If this is the same question as i last saw then the answer is <ABC
1/5 - 5/6 = -19/30, so the answer is Y ≤ 19/30

Answer:
52
Step-by-step explanation:
If u=(a1i+b1j)=(a1,b1) and v=(a2i+b2j)=(a2,b2), then the dot (scalar) product is:
u.v=(a1,b1).(a2,b2)
a1b1+a2b2
u.v=(8,-7).(3,−4)
(8)(3)+(-7)(−4)
24+28=52
