Find the coordinates of d if e (-6,4) Is the midpoint of df and f has coordinates (-5,-3)

Mathematics
1 answer:
Oksanka [162]3 years ago
4 0

Answer:

Step-by-step explanation:

Let the coordinates of d be (x,y)

The midpoint of (x,y) and (-5,-3) is equal to ((-5+x)/2, (-3+y)/2)

this should be equal to the coordinates of e, (-6,4)

we have (-5/2+x/2, -3/2+y/2)

-5/2+x/2 = -6

-5 + x = -12

x = -7

-3/2+y/2 = 4

-3+y = 8

y = 11

Therefore the coordinates of d are (-7,11)

Helene is finding the sum (9 10i) (–8 11i). She rewrites the sum as (–8 11)i (9 10)i. Which statement explains the property of a
Andreyy89

She made the mistake of grouping unlike terms and factorizing.

Given that

Helene is finding the sum (9 + 10i) + (–8 + 11i).

She rewrites the sum as (–8 + 11)i + (9 + 10)i.

We have to determine

Which statement explains the property of addition that she made an error in using?

According to the question

The mistake she did is in the second term distributing.

(9+10i) is not equal to (9+10)i

Similarly (-8+11i) is not equal to (-8+11)i.

The correct method she should have done is given below;

Grouping real terms together and imaginary terms together and finding the sum is,

\rm =  (9 + 10i) + (-8 + 11i)\\\\= 9+10i-8+11i\\\\= (9-8) +(10i+11i)\\\\=1+21i

Hence, she made the mistake of grouping unlike terms and factorizing.
