Answer:
9 (i - 1)
Step-by-step explanation:
Simplify the following:
-7 + 3 i - (-6 i + 2)
-(2 - 6 i) = -2 + 6 i:
6 i - 2 - 7 + 3 i
-2 + 6 i - 7 + 3 i = (6 i + 3 i) + (-2 - 7) = -9 + 9 i:
9 i - 9
Factor 9 out of 9 i - 9 giving 9 (i - 1):
Answer: 9 (i - 1)
Step-by-step explanation:
just add them all up and divide by the number of items. in this case divide by 10
The answer is d to the question
Answer:
$3 for 1 book.
Step-by-step explanation:
51) 5x-1=0 and x+6=0
5x=1, x=1/5 and x=-6
2 solutions x=1/5 and x=-6
52)x(2x+3)=0
2x=0 and 2x+3 =0
x=0 and x=-3/2=-1.5
53) x(5x-1)=0
x=0 and 5x-1=0
x=0 and x=1/5
54) z(4z+7) =0
z=0 and 4z+7=0
z=0 and z= - 7/4 = -1.75
z=0 and z=-1.75
