Answer:
(x) = x - 3
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x + 3 (subtract 3 from both sides )
y - 3 = x
Change y back into terms of x with x = (x) , thus
(x) = x - 3
The answer would be 480 and because you multiply 30 times 12 you will get 360 and then you add that to the money he already has which is 120 so the total amount is 480
Answer:
He must sell 800 bushels.
Step-by-step explanation:
Divide 2400 by 3, giving you 800.

Step-by-step explanation:
Since p(x) = x² + 2 , if x ≤ 4
For x = 4 then this is included in the inequality x ≤ 4
whereas x > 4 does not include x = 4 but values greater than 4
Thus to evaluate x = 4 use p(x) = x² + 2
