(40 - x) represents A. the number of undamaged cards
Step-by-step explanation:
Step 1; Maria has a total of 40 cards out of which x number of cards are damaged so 40 - x cards are undamaged. The value of an undamaged card is 5 dollars whereas every damaged card has a value of 3 dollars.
Step 2; We need to determine what each term in equation 5(40−x)+3x represents. The equation will give us how much total value Maria's card collection has.
The first term 5 (40 - x) signifies the total value of the undamaged cards in the deck where (40 - x) equals the total number of undamaged cards.
The second term represents the total value of the undamaged cards.
So the second factor of the first term i.e (40 - x) represents the amount of undamaged cards in her collection.
Answer:
(-∞ 2] ∪ [-4/3 ∞ )
Step-by-step explanation:
Given compound inequality,
( Subtraction property of inequality )
( Division property of inequality )
( a < b ⇒ - a > - b )
Hence, the solution of the given inequality is,
(-∞ -2] ∪ [-4/3 ∞ )

Answer:
<em>option: B</em> is correct.
Step-by-step explanation:
in order to graph point D whose coordinates are (4,4)
in order to graph a vertical line(V) passing through point D the line will be parallel to y-axis and passes x-axis at the point (4,0)
hence the equation of such a line will be x=4.
in order to graph a horizontal line(H) passing through point D the line will be parallel to x-axis and passes y-axis at the point (0,4)
Hence the equation of such a line is y=4.
Hence V: X=4
and H: y=4
Hence, option B is correct.
