When your exponent is negative, you move your decimal.. A)to the right
B)to the left
C)to both sides
D)nowhere the
decimal goes
nowhere

B) point to the left

Step-by-step explanation:

To write each of these numbers in decimal notation, you move the decimal point the same number of places as the exponent. If the exponent is positive, move thedecimal point to the right. If the exponent is negative,move the decimal point to the left

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
