. Ticket prices for the upper deck are 75% of the cost of tickets for the lower deck.
Which inequality represents all possible combinations of x, the number of tickets for the lower deck, and y, the number of tickets for the upper deck, that someone can buy for no more than $800?
A) 42x + 56y ≤ 800
B) 42x + 31.5y ≤ 800
C) 42x + 56y > 800
D) 42x + 31.5y > 800

X=42$
y=0.75*42$=31.5$

42*42+56*31.5=3528
42*42+31.5*31.5=2756.25
C and D are correct inequalitys

<span>If tickets for the upper deck are 75% of the cost of tickets for the lower deck and lower deck tickets are $42, then tickets for the upper deck $31.50 each. Therefore the answer cannot be A or C, because both of those options misstate the cost of the upper deck ticket. The answer also cannot be D, because it expresses the inequality when the combined number of tickets is greater than $800, which is not what was asked for. The correct answer is B. 42x + 31.5y ≤ $800. This gives the correct price for upper deck tickets and expresses the correct inequality.</span>

Find (fog)(x). f(x) = 2x
Blababa [14]

Answer: (f•g)(x)=​2x²+12x

Step-by-step explanation:

(f•g)(x) is the same as saying f(x)•g(x). Since we have f(x) and g(x), we can just multiply them together.

(f•g)(x)=​2x(x+6)                [distribute by FOIL]

(f•g)(x)=​2x²+12x              

Now, we know that (f•g)(x)=​2x²+12x.

Which equation would you use to find how high the bird is flying
lisov135 [29]
Hi there! The fourth answer is correct.

In the picture we have to deal with facts:
1. The angle of 45°
2. The length of the opposite side
3. The length of the adjacent side.

Since we have to use the opposite and the adjacent side, we have to use the tangent of the angle. In a formula:
\tan( \alpha ) = \frac{opposite}{adjecent}

Filling in this formula, brings us to the following answer.
\tan(45) = \frac{x}{1100}
