-3Ix + 7I = -12 (divide -3 from each side)
Ix + 7I = -12/3
Ix + 7I = -4
x + 7 = -4 or -x - 7 = -4
x = -11 or -x = 3
x = - 3
x = -3 or -11
Answer:
<em>Hey there Marcus! LOL Anyways.. this answer would be..</em> It is one-half the area of a rectangle of length 4 units and width 5 units.
.00008 would be the answer. You would have to move the place the decimal to get this answer. Hope it helps
Answer:
The roots are not real.
Step-by-step explanation:
To prove : The roots of I/2 +9 (1-k) are real for all real values of k ?Solution :
The roots are real when discriminant is greater than equal to zero.
i.e b2-4ac>0 But the roots are imaginary therefore the roots of the given equation are not real for any value of k.If x²+kx+k=0, find the value of k, If the roots are real & equal.
