Answer:
x = 5, x = 11
Step-by-step explanation:
Set f(x) = 0 and solve for x.
0 = (x -8)² -9
9 = (x -8)² . . . . . add 9
±√9 = x -8 . . . . . take the square root
±3 +8 = x . . . . . . . add 8
That is, ...
x = 8 -3 = 5 . . . . lesser x
x = 8 +3 = 11 . . . greater x
Answer:
2 1/5
Step-by-step explanation:
First you make both fractions into 5 becomes 25/5. 2 4/5 becomes 14/5. Then you would just subtract 25/5 - 14/5 = 11/5 then make it a mixed number 2 1/5.
They both can be divided by 2 to make it 7: 28. Then, it can be divided by 7 to make it 1:4
