Answer:
<em>40 + 5x ≤ 50</em>
Step-by-step explanation:
<u>Inequalities</u>
The maximum weight allowed for checked bags on a particular airline is 50 pounds.
Jennifer has already used up to 32 pounds of clothes and the empty suitcase weighs 8 pounds. This makes a weight of 40 pounds already used.
If five identical gifts of x pounds each are to be included in the suitcase, the total weight is 40 + 5x. And that weight cannot exceed 50 pounds, thus:
40 + 5x ≤ 50
That is the inequality to represent the situation.
Answer:
x = 6
Step-by-step explanation:
Given
3x + 30 + x = 10 + 2x + 5x + 2 , simplify both sides
4x + 30 = 7x + 12 ( subtract 7x from both sides )
- 3x + 30 = 12 ( subtract 30 from both sides )
- 3x = - 18 ( divide both sides by - 3 )
x = 6
|Ω| = 6 - number of all results
A = {1, 3} → |A| = 2 - number of (a) results
P(A) = 2/6 = 1/3
Answer:
A, B, C
Step-by-step explanation:
4 - (-5) + 0
4 - (-5) = 4 + 5 (because a negative + negative = positive)
4 + 5 = 9
a, b and c all equal 9
hopefully this helped you!! :3
Answer:
The function is even because f(x) = f(−x).
Step-by-step explanation:
we know that
An even function is one for which
f
(−x)=f(x) for all x in its domain.
An odd function is one for which
f(
−x)
=−f(x) for all x in its domain
In this problem we have
so
therefore
f
(x)=f(-x) for all x in its domain.
Is a even function
