Answer:
6
Step-by-step explanation:
Answer:
-1, 0, 1, 2, 3
Step-by-step explanation:
Solve two equations:
-5 < 2n-1 => -4 < 2n => n > -2
and
2n-1 ≤ 5 => 2n ≤ 6 => n ≤ 3
so
-2 < n ≤ 3
then enumerate the possible values for n
-1, 0, 1, 2, 3
Answer: $54.35
Step-by-step explanation:
If each one of the 15 students raises the same amount, let's define this amount by the variable X, then the total amount they will collect is 15 times X, or:
15*X
And the minimum amount they need to collect is $800
Then we will have the inequality:
15*X ≥ $800
Now we can divide both sides by 15 to get the minimum amount that each student needs to raise:
(15*X)/15 ≥ $800/15
X ≥ $54.33...
Where we should round up the right number to $54.35, because we can not have a $0.0333... and if we round down, they would collect less than $800.
Then the inequality is:
X ≥ $54.35
This means that the minimum amount that each one of the 15 students needs to collect is $54.35
<h3>
Answer:</h3>
B. mx−y=−b
<h3>
Step-by-step explanation:</h3>
Start with ...
... y = mx +b
Subtract mx.
... -mx +y = b
You want the leading coefficient positive, so multiply by -1.
... mx -y = -b . . . . matches selection B
