X = additional mile
0.85x + 1.65 = 20
to solve it:
subtract 1.65 from both sides. afterwards, divide both sides by 0.85 to find x!
We have two points describing the diameter of a circumference, these are:
Recall that the equation for the standard form of a circle is:
Where (h,k) is the coordinate of the center of the circle, to find this coordinate, we find the midpoint of the diameter, that is, the midpoint between points A and B.
For this we use the following equation:
Now, we replace and solve:
The center of the circle is (-8,-7), so:
On the other hand, we must find the radius of the circle, remember that the radius of a circle goes from the center of the circumference to a point on its arc, for this we use the following equation:
In this case, we will solve the delta with the center coordinate and the B coordinate.
Therefore, the equation for the standard form of a circle is:
In conclusion, the equation is the following:
Answer:
- Any of x = {-3, 5, -1, 0}
Step-by-step explanation:
Since the relationship in the table is not a function, Rae could put any values for x that is already in the table.
This will result in repeat of x-values with different corresponding y-values.
Label the number line, put a filled in circle on 2 and make it go left. Then put a clear circular on 2 and make it go right.
