Answer:
(12, 3)
Step-by-step explanation:
write the equation:
if x = number of 2 point shots
and y = number of 3 point shots
2x + 3y = 33
write another equation with the total baskets
x + y = 15
plug them both into desmos and find the solution
(12, 3)
she made 12 2-point shots and 3 3-point shots
Answer:
20,053
Step-by-step explanation:
20,335 - 282 = 20,053
Answer:
(x + 4)^2 + (y - 8)^2 = 81
or
(x + 4)^2 + (y - 8)^2 = 9^2 depending on how your teacher wants it written.
Step-by-step explanation:
The standard form for a circle is
(x + h)^2 + (y + k)^2 = r^2
r is the radius.
You are given the diameter
r = d/2
r = 18/2
r = 9
So you already have the right hand side of the equation
(x + h)^2 + (y + k)^2 = 9*2
(x + h)^2 + (y + k)^2 = 81
You basically have h and k as well. They come from the center point.
h = 4
k = - 8
So the equation of the circle (and the answer) is
(x + 4)^2 + (y - 8)^2 = 81
One question remains. Why do the x and y values change signs? If you know what the distance formula is, then what you are finding is the distance r of all points on the circle from the center of the circle.
It is the distance formula that is actually the formula for the circle.
1 and 19, 19 is a prime number.
