The standard form of a circle is (x-h)+(y-k)^2=r^2
h and k represent the center of the circle and to find the center you have to find the midpoint of the two endpoints.
the midpoint formula states to find the average of the x values and the y values (to find the average you add the terms together and divide by however many you have.. In this case add the two x/y terms and divide by 2).
the midpoint is (-6,-10) which means that the standard form would be
(x+6)^2+(y+10)^2=r^2
but you still have to find the measure of r, the radius. So you'd use the distance formula to find the diameter and divide by 2 to find the radius.
distance formula is d=√(x-x)²+(y-y)²
so the diameter is 4√5, divide by 2 and the radius is 2√5
STEP ONE:
Set up the equation
45.25 + 7.25x = 25.25 + 9.75x
STEP TWO:
Subtract 7.25x from both sides
45.25 = 25.25 + 2.5x
STEP THREE:
Subtract 25.25 from both sides
20 = 2.5x
(Flip equation)
2.5x = 20
STEP FOUR:
Divide 2.5 from both sides
x = 8
Since x represents weeks, it will take 8 weeks for Brian and Dakota to have the same amount of money.

3/10 or 30/100 are left handed boys bc that is 30% converted into a fraction
Answer:
3.875
Step-by-step explanation:
Your answer would be A. positive linear association.
If we break this phrase down, we first get "positive", which we can see is true here as the graph is ascending towards the top right, that is, going upwards and 'forwards'. This is how we recognise lines with positive slopes, such as 3x or (1/2)x.
The word "linear" means a straight line, you can sort of see the word "line" in it, and so this is also true as the trend line is straight.
I hope this helps!
