Answer:
BF = 30
Step-by-step explanation:
Since B and F are midpoints then BF is parallel to CE and half it's size
BF = 0.5 × CE = 0.5 × 60 = 30
The third one, 40-45 because the difference of the rest are 4, while that one is 5.
Answer:
Step-by-step explanation:
x + 8 = -x - 6
2x + 8 = -6
2x = -14
x = -7
y = -7 + 8
y = 1
(-7, 1)
We have the expression:

When we have rational functions, where the denominator is a function of x, we have a restriction for the domain for any value of x that makes the denominator equal to 0.
That is because if the denominator is 0, then we have a function f(x) that is a division by zero and is undefined.
If we have a value that makes f(x) to be undefined, then this value of x does not belong to the domain of f(x).
Expression:

Answer: There is no restriction for x in the expression.
