A is the answer.
First, figure out all the coordinates for the points marked red( I Did this for all except first one, which was not on the right point)
They were:
-1,1
0,2
1,4
2,8
3,16.
Then, we must do trial and error for each of the options until we find one that fits perfectly. Luckily, the first option was right!
Hope this helps
If you graph 4 separate triangles with the four different points, (2,3) and (1,5) form a right triangle.
Answer:
x = 4 and y = - 5
Step-by-step explanation:
note that the product of a complex number and it's conjugate is real
That is
(a + bi)(a - bi) where a, b are real
= a² - abi + abi - b²i²
= a² + b² ← a real number
For (4 + 5i)(x + yi) to be real
we require (x + yi) to be the conjugate of 4 + 5i , that is 4 - 5i
(4 + 5i)(4 - 5i) ⇒ x = 4 and y = - 5

Answer:
1 7/15
Step-by-step explanation:
2-1=1
then you make 2/3 and 1/5 have the same denominator -
5*3=15
?/15 ?/15
multiply 2 by 5 which is 10, so 10/15
then multiply 1 by 3 which is 3/15
subtract 3/15 from 10/15 which is 7/15
