Answer: Choice C) Multiplication property of inequalityThe rule basically says that if you start with a < b and you multiply both sides by some positive number c, then a*c < b*c. The sign doesn't flip if you multiply both sides by a positive number.
The sign will flip if c is negative. So we'll go from a < b to a*c > b*c if c is negative.
Example 1:
1 < 5
-2 > -10 ... multiplied both sides by -2; sign flips
Example 2:
3 < 7
9 < 21 ... multiplied both sides by 3; sign does not flip
Similar rules apply to a > b,
and
Answer:
p = 2.70 or p = 17.30
Step-by-step explanation:
You want to find p such that ...
1200 = -3p² +60p +1060
3p² -60p +140 = 0
Using the quadratic formula, the values of p are ...
p = (-(-60) ±√((-60)² -4(3)(140)))/(2(3)) = (60 ±√1920)/6
p = 10 ± (4/3)√30 ≈ 2.70 or 17.30
A price of $2.70 or $17.30 will result in revenue near $1200.
Answer:
Total donation by Alonzo's mother = $40.
Step-by-step explanation:

Answer:
1 18
2 36
3 54
4 72
Step-by-step explanation:
18 m/s every second means you multiply the time by rate (to get the distance traveled in 2 seconds, multiply 18m/s by 2 to get 36)
