Answer:
y = 5.5
Step-by-step explanation:
The total distance between the lines j and l is 10.
The total distance between the lines k and l is 9.
To find the distance between the lines j and k we can use the given information.
10 (distance between j and l) - 9 (distance between k and l) = 1 (the distance between the lines j and k).
So the distance between lines j and k is 1.
In the given picture the distance is shown as 2y-10.
This means 2y - 10 = 1
Now we need to solve this equation to find y.
2y - 10 = 1
2y = 1 + 10
2y = 11
y = 11/2
y = 5.5
(NOTE: We are not including 4 in the process of finding the value of y because this particular line is not similar to the line where y is )
Answer:
cx +cy = a² + b²
Step-by-step explanation:
In the end, he wants to show that c² = a²+b², so he will want to form the sum a²+b². That sum can be formed by adding the expressions for a² and b² just found:
cx +cy = a² + b² . . . . . . . Todd's next step

Then the following steps are ...
c(x+y) = a² + b²
c² = a² + b²
I think its is a small exponents
f(x) = sqrt [( x - 3) / (x - 5)]
well x cannot be 5 because that would make x - 5 = 0.
Also the fraction x - 3 / x - 5 cannot be negative because theres no real square root of a negative.
So x must be <= 3 or > 5
In interval notation the domain is ( -∞,3] or (5 , ∞)
