Answer:
The line given is equal to y=-x+7 (Through rearranging)
To find the new line, we substitute the given coordinates (5,8) in the equation without the given y-intersect (+7):
-8=-5+c
c=-3
The line parallel to x+y=7 that passes through the point (5,-8) is y=-x-3
Basically each part of the first complex number gets multiplied by each part of the second complex number. You are multiplying 2 binomials.
(15 + 56i(7 + 4i)
= 105 + 60i + 392i + 224i^2
= 105 + 452i - 224 ( because i^2 = -1)
= - 119 + 452i
<em>the remainder is </em><em>- 1</em>
- Step-by-step explanation:
<em>when (x ³ - 7x + 5) is divided by (x + 3) the remindeer is f( -3 )</em>
<em>x + 3 = 0 => x = - 3</em>
<em>f(-3) = (-3)³ - 7(-3) + 5</em>
<em>= - 27 + 21 + 5</em>
<em>= - 1</em>
