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).
I think the value of x may be x
Answer:
x = 8 and y = - 1
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (8, - 1 ) with x- coordinate 8, then
x = 8 ← equation of vertical line
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through
The line passes through (8, - 1 ) with y- coordinate - 1, then
y = - 1 ← equation of horizontal line
