Answer: Cost of tickets for adults = $22

Cost of tickets for children = $15

Total number of tickets sold = 732

Total receipts = $12,912

Let x be number of adult ticket's sold and y be the number of child ticket's sold.

Therefore, we have:

x+y=732       --------------- equation 1

x=732-y

Also, we have:

22 x+15y=12,912

Now, let's substitute the value of x:

22 (732-y)+15y=12912

16104-22y+15y=12912

16104-7y=12912

7y=16104-12912

7y=3192

y=\frac{3192}{7} =456

Now, let's substitute the value of y=456 in equation 1, we have:

x+456=732

x=732-456

x=276

Therefore, the number of child ticket's sold is 456 and number of adult ticket's sold is 276

When the expression 2y – 3 + 7x + 4y – 2x is simplified, what is the new expression?
uysha [10]

Answer:

6y + 5x - 3

Step-by-step explanation:

Simplifying an expression simply means to collect like terms that are having the same variables or constants and combining them, so as to reduce the expression to the lowest possible value.

Given the expression;

2y – 3 + 7x + 4y – 2x

Collecting like terms, we have;

Expression = 2y + 4y + 7x - 2x - 3

Expression = 6y + 5x - 3

The output y and input x of a device are related by y = x + 1.4x3 . (a) Find the values of the output for steady-state operation
erma4kov [3.2K]

Answer:

a) y(1) = 2.4 , y(2) = 13.2, b) y(x) = 2.4 + 5.2\cdot (x-1), y(1) = 2.4, y(2) = 7.6

Step-by-step explanation:

a) The values of the output for steady-state operation are:

y(1) = 1 + 1.4\cdot (1)^{3}

y(1) = 2.4

y(2) = 2 + 1.4\cdot (2)^{3}

y(2) = 13.2

b) The formula for linearization is:

y(x) = y(1) +\frac{dy}{dx}|_{x = 1} \cdot (x-1)

The first derivative of the formula evaluated at x = 1 is:

\frac{dy}{dx}|_{x=1} = 1 + 4.2\cdot (1)^{2}

\frac{dy}{dx}|_{x=1} = 5.2

The linearized model is:

y(x) = 2.4 + 5.2\cdot (x-1)

The output at x = 2 is presented below:

y(2) = 2.4 + 5.2\cdot (2-1)

y(2) = 7.6

Linearized model offers reasonable approximations for small intervals.
