Hey, im not really sure but i think it is that 1. x=96 y=11 2. x=16 y=15 3.x=81 y=18
Then you just substitute the numbers into the letters. For example,
11-96(2)= -181
15-16(2)= -17
18-81(2)= -144
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,

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

Find m or the slope of the two coordinates first.
M = y2-y1 / x2-x1
= 5 - (-1) / 1 - (-1)
= 6 / 2
= 3
Now that you have the slope, we can use the equation of a line which is :
y - y1 = m(x - x1)
Substitute any coordinate.
I'll go with (1, 5)
y - 5 = 3(x - 1)
y - 5 = 3x - 3
y = 3x + 2
And that's the equation in the slope intercept form or y=mx+b.
Area of circle : A= pi(r)^2
d = 14 : 2 = 7
=> A = pi(7)^2
=> A = 153.94
B is correct
