I hate those F***! Rip my guy
0.7 or 7/10. If the hundreths place is less than 5 you keep the tenths place as it is. If it is 5 or greater you round up and have the tenths place be one number higher. In this case you keep .7 because the hundreths place is lower than 5. Hoped this helped!
Shouldn't the equation read " (x - 4)² = 81 ", instead of "(1 - 4)² = 81" ?
If so, then the solutions are x = -5 and x = 13 .
If it's really "(1 - 4)² = 81", then that's not even an equation, and there's no solution.
Add 5 and eliminate parentheses
... y = -2x +6 +5
Simplifying, you get
... B. y = -2x +11
