Answer: +5
Explanation: When a problem is asking us to find the absolute value of a number, it's really asking us how far is that number from zero.
So the absolute value of -5 is really asking us
how far is -5 away from zero on a number line.
I have drawn a number line below and you can see that -5
is 5 units to the left of zero which means its 5 units from zero.
So the absolute value of -5 is +5.
Answer:
Step-by-step explanation:
Using the Foil method
you multiply x times x and get
Then you multiply -4 times X and get -4x
Then you multiply -3 times X and get -3x
then you add -4 and -3 together and get -7x
Lastly you multiply -4 and -3 and get 12
And there you have it
We need to find the center and the radius of
The general circle equation is the following
where
(h,k) is the center and
r is the radius
1. rearrange the equation
2. Add 25 on both sides
3. Factor
Now we have an equation that is very similar to the circle equation, so let's compare them
Center -> (h,k) = (5,-11)
radius -> r = 5
