Answer:
255
Step-by-step explanation:
If the sum of digits is 12, the number is divisible by 3. If the number ends in 0 or 5, it is divisible by 5. So, we're looking for ...
2x0 . . . where x is a digit and 2+x+0 = 12 . . . . . . not possible
2x5 . . . where x is a digit and 2+x+5 = 12 . . . . true for x=5
The number is 255.
Every x value should have only one value of y.
So the answer is the last choice.
Y= ∛(-x) - 3
for x = -8 → y = ∛-(-8) - 3 ↔ y = 2-3 ↔y = -1
for x= 8 → y= ∛(-8) - 3 ↔ y = -2 -3 ↔ y = -5
Then - 5≤ y≤ - 1
hence the range of y is {y|-5≤y≤-1}
Answer:
=3–√−13–√+1⋅3–√−13–√−1
=(3–√−1)23–√2−12
=3–√2+12−23–√3−1
=4−23–√2
2−13–√
a=2,b=−1.
