A.) Mark is correct as every increase in x of 2 equals a y increase of 4
Answer:
Option A is correct.
Step-by-step explanation:
We are given:

We need to find the value of a.
The LCM of (2+i) and (3+i) is (2+i)(3+i)

Now rationalize the denominator by multiplying by 5-5i/5-5i

We are given

Now after solving we have:

So value of a = 1/10 and value of b = -1/10
So, Option A is correct.
X=7. The two segments on the bottom as well as on the diagonal are the same length. This shows that the entire triangle and the inner triangle on the right are similar. So if we call the length of the bottom 2y, then 84/2y=6x/y. Solving this we get 84=12x, and so x=7
The rate of change is 110 percent.
