First we round it off to the nearest millions.

6,852,472,823 rounded off - 6,852,000,000

then you move the decimal point to the left until the number becomes between 1 and 10

-- 6.852000000

count the numbers to the right of the decimal point, remove the zeroes, then write it as

6.852 x 10^9 or 6.852e9

9 is how many numbers are in the right of the decimal point, which was 852000000

What is the solution of 2x^2+8=x^2-16

AfilCa [17]

Answer:

x = -12

Step-by-step explanation:

2x^2 + 8 = x^2 - 16

2x + 2x + 8 = x + x - 16

4x + 8 = 2x - 16

-2x -2x

2x + 8 = -16

-8 -8

2x = -24

Answer:

A. The y-intercept of g(x) is less than the y-intercept of f(x).

Step-by-step explanation:

The x-intercept, or when x = 0, of f(x) is -4, the x-intercept of g(x) is -8, so g(x) are neither greater nor equal to f(x), this marks out C and D. The y-intercept, or when y = 0, is in this case f(x) or g(x). The y-intercept of f(x) is 16, the y-intercept of g(x) is 4, so the y-intercept of g(x) is not equal to the y-intercept of f(x), this marks out B. Now to check A, 4 < 16, so y-intercept of g(x) < y-intercept of f(x), the answer is A
