The answer is a 20.
you do 20 * 15 = 300
700-300 = 400 divide by 10 which is 40
20(x) + 40(y) equals 60
Add the numbers up, then take the percentage sign away and there you have it! A number all fresh, new and crisp!
Answer:
The point (b, f(b)) is a local maximum.
Answer:
See explanation
Step-by-step explanation:
1. R is the set of all integers with absolute value less than 10, thus
2. A is its subset containing all natural numbers less than 10, thus
3. B is the set of all integer solutions of inequality 2x+5<9 that are less than 10 by absolute value (and therefore, it is also a subset of R). First, solve the inequality:
Thus,
