Answer:
Step-by-step explanation:
For question 4, the top equation has an x and a y value in it. The second equation is just a y value. So put the 4 into the top equation.
4 = x - 2 Add 2 to both sides
4 + 2 = x -2 + 2
6 = x
You can actually graph this to show that the solution set is (6,4) The solution set is marked (6,4).
The read line is y = x - 2
The blue line is y = 4

Given:
Circle C and circle R are similar.
The length of arc AB is
The radius of circle C (AC) = 4 unit
The radius of circle R (QR) =6 unit
To find the length of arc QP.
Formula
The relation between s, r and is
where,
s be the length of the arc
r be the radius
be the angle.
Now,
For circle C
Taking r = 4
According to the problem,
or, [ eliminating
from both side]
or,
or,
Again,
For circle R
Taking, r = 6 and we get,
The length of arc QP is
or,
Hence,
The length of QP is . Option C.
