Answer:M=4
Step by step answer
9x^2-mx^2+12x-3=5x^2+12x-35
9x^2-mx^2+12x-3+3=5x^2+12x-35+3
9x^2-mx^2+12x=5x^2+12x-32
9x^2-mx^2+12x-12x=5x^2+12x-32-12x
9x^2-mx^2-5x^2=5x^2-32-5x^2
-mx^2+4x^2=-32
x^2(-m+4)=-32
M=4

Answer:
The equation given has no solution.
Step-by-step explanation:
The equation given is:
Therefore, this is false.
Answer:
-3 - 2i
Step-by-step explanation:
conjugate of a+bi is a-bi, so conjugate of -3 + 2i = -3 - 2i
1. combine like terms (2x and -7x) to create -5x
2. subtract 5 from each side to create: -5x=10
3. divide both sides by -5
4. x=-2
