Answer:
k=(-7y+11)/4
Step-by-step explanation:
Given
11(k-1)= 7(k-y)
In order to find the value of K we have to separate k on one side, so
Multiplying 11 and 7 into the brackets on both sides
11k-11=7k-7y
Subtracting 7k on both sides
11k-11-7k=7k-7y-7k
11k-7k-11= -7y
Adding 11 to both sides
4k-11+11= -7y+11
4k= -7y+11
4k=-7y+11
k=(-7y+11)/4
So the value of K is (-7y+11)/4.

Answer:
if x=-1 then its is NOT in the domain of h.
Step-by-step explanation:
Domain is the set of values for which the function is defined.
we are given the function
h(x) = x + 1 / x^2 + 2x + 1
h(x) = x+1 /x^2+x+x+1
h(x) = x+1/x(x+1)+1(x+1)
h(x) = x+1/(x+1)(x+1)
h(x) = x+1/(x+1)^2
So, the function h(x) is defined when x ≠ -1
Its is not defined when x=-1
So, if x=-1 then its is NOT in the domain of h.
Answer:
Wrong. If the line segment AB= 10, then the measure of AC= 10 as well. It's a right triangle. All the sides are the same.
