Answer:
where is the spinner
Step-by-step explanation:
let each of the numbers be x :
Answer:
x^2 + y^2 = 4
Step-by-step explanation:
The center-radius form (formally called the standard form) of a circle is
(x-h)^2+(y-k)^2=r^2 where (h,k) is the center and r is the radius.
So if we replace (h,k) with (0,0) since the center is the origin and r with 2 since the radius is 2 we get:
(x-0)^2+(y-0)^2=2^2
Let's simplify:
x^2 + y^2 = 4
-2(3x - 9) + 5x = -10
-6x + 18 + 5x = -10
-6x + 5x = -10 - 18
-x = -28
x = 28 <===
Answer:
<h2>y = -4x</h2>
Step-by-step explanation:
Solve 20x + 5y = for y
20x + 5y = 0
subtract 20x both sides
5y = -20x
simplify:
y = <u>-20x</u>
5
finally
y = -4x
