You have the original function as 2x-5
and you are given the value of x to be -1/2
Therefore, all you have to do is substitute the value of x in the function and calculate it as follows:
f(-1/2) = 2(-1/2) - 5 = -1 -5 = -6
For this case we have the following polynomials:

To divide the polynomials we must follow the following steps:
1) Same base, the exponents are added.
2) Only terms that have the same exponent can be added or subtracted.
3) If the remainder is zero, the division is exact.
Answer:
Note: see attached image for the solution.
Answer:
True
Step-by-step explanation:
True because if AC = BC, then the triangles are the same.
