Answer:
2 and 3 are the only true statements
This is the concept of algebra, we are required to subtract the complex numbers. Thus;
(5-2i)-1(1+8i)
opening the brackets using the distributive property we get:
5-2i-1-8i
collecting the like terms we get:
5-1-2i-8i
=4-10i
the answer will therefore be:
4-10i
Answer:
The coordinates of point B are (3,-2)
Step-by-step explanation:
we know that
The rule of the reflection of a point across the y-axis is given by
(x,y) -----> (-x,y)
so
Applying this rule to the point A(-3,-2)
A(-3,-2) --------> B(3,-2)
therefore
The coordinates of point B are (3,-2)
Okay sub equation 2 into equation 1:
so it becomes
x + 3x = 8
4x = 8
x = 2
then 2 + y = 8, therefore y = 6
So the answer is B
