Write the equation of a circle graphed. A) x^2 + (y - 4)^2 = 16 B) x^2 + (y + 4)^2 = 16 C) (x - 4)^2 + y^2 = 16 D) (x + 4)^2 + y^2 = 16

just put them in order

step-by-step explanation:

-6 is the correct option from the above given options

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
