2x + 30 = -20x + 8
2x + 20x = 8 - 30
22x = -22
x = 1
260,880 as (2 times 100,000)+(6 times 10,000)+(8 times 100).
here Sophia must consider 80 as 8 times 10
so that complete expression becomes
260,880 = (2 times 100,000)+(6 times 10,000)+(8 times 100)+(8 times 10)
Answer:
is a way to express the definition of a circle on the coordinate plane.
Step-by-step explanation:
We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. Then complete the square for the y terms.
