Baseball fans can buy tickets for seats in the lower deck or upper deck of the stadium. Tickets for the lower deck cost $42 each

. 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>

I need help with number 4
ss7ja [257]

Answer:  Choice D

f^{-1}(x) = (x-3)^2+2\\\\

============================================================

Explanation:

First we replace f(x) with y. This is because both y and f(x) are outputs of a function.

To find the inverse, we swap x and y and solve for y like so

y = \sqrt{x-2}+3\\\\x = \sqrt{y-2}+3 \ \text{ .... swap x and y; isolate y}\\\\x-3 = \sqrt{y-2}\\\\(x-3)^2 = y-2 \ \text{ ... square both sides}\\\\(x-3)^2+2 = y\\\\y = (x-3)^2+2\\\\f^{-1}(x) = (x-3)^2+2\\\\

Note: because the range of the original function is y \ge 3, this means the domain of the inverse is x \ge 3. The domain and range swap roles because of the swap of x and y.

As the graph shows below, the original and its inverse are symmetrical about the mirror line y = x. One curve is the mirror image of the other over this dashed line.

<span>2x+3y=11
Y= -2x + 1 re-write -2x - y = -1
so
</span>2x + 3y =11
-2x - y  = -1
--------------add
2y = 10
y = 5

<span>Y= -2x + 1
</span>5 = -2x + 1
-2x = 4
x = -2

The probability of getting a 6 after rolling a fair dice 16.
Butoxors [25]

Answer:

P(6) = 5

Step-by-step explanation:

The dice is cast 30 times (k = 30)

So if the big numbers apply, then you would expect the outcome to be evenly distributed, meaning

5 x 1

5 x 2

5 x 3

5 x 4

5 x 5

5 x 6

____ +

30 casts in total (evenly distributed over all numbers of the dice)

P(6) = 1/6 * 30

P(6) = 5
