Plug in 3 to x:
f(x) = 3³ - 7
Solve:
f(x) = 3³ - 7
f(x) = 3 · 3 · 3 - 7
f(x) = 9 · 3 - 7
f(x) = 27 - 7
f(x) = 20

Iliana is correct since an integer means a whole number that is not a fraction, which includes negative AND positive numbers.
If s=4 than -s is negative (-4)
But if we plug in a negative integer, like -5, the negative signs are eliminated and it becomes positive, therefore Alonso is wrong (-s=-(-5)=5)
If the question was about a natural number Alonso would have been right since natural numbers are only from 0 and above
Answer:
x*(2/3)=y
y*1.5=x
Step-by-step explanation:
There is 2/3rds the amount of sodium in the new one, y. If you multiply the odl one, x, by 2/3, you'll have the amount in the new one. Because half of 2/3rds is 1/3, if you multiply the new one by 1.5, you'll end up with 3/3, or 1, which is the amount in the old one.
