The midpoint of AB AB is at (3,7) (3,7) and A A is at (0,−5) (0,−5) . Where is B B located

1 answer:

8 0

I believe the answer is (6, 29)

The reasoning for this is the slope for (0,-5) and (3,7) is:
7+5/ 3-0
12/3

So if we start at (3,7) and move the x over 3 it will be at 6
and if we move the 7 over 12 it will be at 29
thus the answer should be (6,29)

Hope this answer helps!

Answer:

None of those options

Step-by-step explanation:

I just did the work myself and even ran it through a calculator but the correct answer isn't one of those options. Here's my work:

$-\frac{5}{6} =z+\frac{1}{8}\\-\frac{5}{8}-\frac{1}{8}=z\\-\frac{40}{48}-\frac{6}{48}=z\\-\frac{46}{48}=z\\-\frac{23}{24}$

I'd contact you teacher about that...it might be an error in their system (it's happened to me a few times before where the correct answer is marked as incorrect or isn't even an option)

3. Which relation is a function?

Pani-rosa [81]

Answer:

Step-by-step explanation:

Recall that functions are defined only if for each value in the domain produces one and only one value in the range.

If we view the relations in the questions as x-y coordinates, this means that for every x-value, you can only have one y-value

Lets evaluate the options:

A) we can see that for x = -3, this gives 2 possible values for y i.e (-3,4) and (-3,8) (hence this is not a function)

C) we can see that for x = 3, this gives 2 possible values for y i.e (3,-8) and (3,8) (hence this is not a function)

D) we can see that for x = -3, this gives 2 possible values for y i.e (-3,4) and (-3,8) (hence this is not a function)
