Let the complex number be x + iy
Then by the pythagoras therem
17 = x^2 + y^2
D will satisfy this equation
4^2 + (-1)^2 = 17
answer is D 4 - i
No... congruent means they are exactly the same, just rotatet or dislocated
Answer: 20
Step-by-step explanation:
a^2+b^2=c^2 (pythagorean theorem where c is hypotenuse)
12^2+16^2=c^2
144+256=c^2
400=c^2
square root of 400=20
Answer:
I put them in slop so
1) y= -2x+9
2) y=5/2x -9
it would help to say what u need to solve it for but hoped it helped
