Answer:
Step-by-step explanation:
x = 55
x + 55 = 110
x + 20 = 75
x + 65 = 120
For this case we have a function of the form:

Where:

We must find the value of the function when
. Substituting:

Thus, the value of the function is 2 when 
Answer:

You find the slope by putting the points in the formula y2-y1/x2-x1
when you plug them in it should look like this
-4 -1/8-8
then you would add or subtract, when you do you would get
-5/0
this can't be divide so the slope of this 2 points is undefined
Hope this helped
Answer:
Step-by-step explanation:
There's a whole family of points.
(x + 1)^2 + (y + 2)^2= 25
The above is an equation that represents a circle.
Three points are marked below 2 of which are easily seen to be 5 units away from the center (-1,-2)
