Answer:
Step-by-step explanation:
x + 5/y^2
x = 2/3
y = 1/3
2/3 + 5 / (1/3)^2 Expand (1/3)^2
2/3 + 5 / (1/9) Put a 1 underneath the 5
2/3 + 5/1 / (1/9) Invert and multiply the second expression
2/3 + 5/1 * 9 Simplify 5/1
2/3 + 5* 9 Combine
45 2/3
I'm not getting any of these. It's possible I'm misreading the question, but what you've given is the result I got. All I can suggest is that you ask your teacher how this is done.
Answer:
D
Step-by-step explanation:
You are given two complex numbers -i and 2+i.
For the complex number z=x+iy, the ordered pair (x,y) represents this complex number on the coordinate plane.
So, the numbers:
is represented by the ordered pair (0,-1)
is represented by the ordered pair (2,1).
Plot these two points on the coordinate plane and coonect them with a straight line. You'll get the last option of graph.

Answer:
4
Step-by-step explanation:
3x-5=7x-21
3x-7x=5-21
-4x=-16 ( divide by -4 both sides)
x= 4
