you would have to do this on your own in order to find this out bud.
Answer:
All are correct.
Step-by-step explanation:
Let x be the number of movies and y be the number of newly released video games.
Larry has a gift card worth 400 for a local entertainment store Movies cost $20 each and newly released video games cost $50 each.
Larry must purchase at least nine items.
Check both inequalities of all given ordered pairs.
For (5,6),
Point (5,6) satisfy both inequalities.
For (10,4),
Point (10,4) satisfy both inequalities.
For (20,0),
Point (20,0) satisfy both inequalities.
For (15,2),
Point (15,2) satisfy both inequalities.
Therefore, all combination of movies and newly released video games Larry could purchase using his gift card.
The value of the expression sec (-π) is equal to -1 if the given expression is undefined.
As given in the question,
Given expression: sec (-π)
Standard position of unit circle: -π is representing semicircle with terminal point on negative x-axis with coordinates (-1, 0)
Hypotenuse = √ (-1)² + 0²
= 1
Value of the expression is given by
sec α = Hypotenuse / Base (x-coordinate)
⇒sec(-π) = 1 / -1
⇒sec(-π) = -1
Therefore, the value of the expression sec (-π) is equal to -1.

405,000,000 - 1.7×10^8
= 4.05 × 10^8 - 1.7 × 10^8
= (4.05 - 1.7) × 10^8
= 2.35 × 10^8
