Answer:
12n-10=14, n=2
Step-by-step explanation:
( Twelve times of a number decreased by 10 is equal to 14 ) This sentence can be written mathematically to be: 12n-10=14
The answer: Add 10 to both sides: 12n-10=14 > 12n-10+10=14+10 > 12n=24
Divide both sides by 12: 12n=24 > > n=2
Answer:
F. -15 + 9i
Step-by-step explanation:
B = (-7 -6i)
Multiply B by F = (-15 + 9i), would give;
B × F = (-7 -6i) × (-15 + 9i)
= -7 (-15 + 9i) - 6i (-15 + 9i)
= 105 -63i + 90i - 54()
But = -1, so that:
105 -63i + 90i -54() = 105 -63i + 90i -54(-1)
= = 105 -63i + 90i + 54
= 159 + 27i
B × F = 159 + 27i
Thus the required complex number is F (-15 + 9i).

Answer:
b > 17
Step-by-step explanation:
In this question, you would have to solve the inequality.
Solve for b:
17b - 21 > 12b + 64
Subtract 12b from both sides:
5b - 21 > 64
Add 21 to both sides
5b > 85
Divide both sides by 5:
b > 17
b > 17 will be your answer.
