The cost of each game is $2.25.

The cost of each ride is $4.50.

Here are the system of linear equations that can be derived from the question:

7g + 2r = 24.75 equation 1

3g + 6r = 33.75 equation 2

Where:

In order to determine the value of g, multiply equation 1 by 3:

21g + 6r = 74.25 equation 3

Subtract equation 2 from equation 3:

40.50 = 18g

g = 40.50 / 18

g = 2.25

In order to determine the value of r, substitute for g in equation 1 :

7(2.25) + 2r = 24.75

15.75 + 2r = 24.75

2r = 24.75 - 15.75

2r = 9

r = 9 /2

r = 4.50

The gambler in a Las Vegas casino lost $150.

According to the question,

We have the following details:

The visitor lost $200 and $50 in a Las Vegas casino.

The visitor won $100.

So, in total, the visitor lost $250 overall.

Now, compare the amount the gambler lost and the gambler won in the casino. So, we notice that the gambler lost more amount.

Now, we will find the total amount lost:

Gambler's net worth = The amount lost - the amount won

Gambler's net worth = $(250-100)

Gambler's net worth = $150

Hence, the gambler lost $150 overall in the casino.

Actual area of the real back yard is 96 [tex]m^{2}[/tex]

[scale]=[drawing]/[real] —-> [real]=[drawing]/[scale]

scale=4 m/3 cm —> 0.75 cm/m

The backyard's measurements in the drawing are 9 x 6 cm.

Determine the backyard's actual dimensions

[Real]=[Drawing]/[Scale] for 9 cm

[real]=[9]/[0.75]——> 12 m

[Real]=[Drawing]/[Scale] for 6 cm

[real]=[6]/[0.75]——> 8 m

The backyard's actual measurements are 8 m × 12 m, and its actual size is 8 * 12 = 96 [tex]m^{2}[/tex].

Consider that the reservation costs $625. Moreover, it is necessary to pay additional $11 per person for food. If x is the number of people, it means that it is necessary to pay 11x dollars for x people.

THen, the total cost is $625 plus 11x dollars. If y is the cost of the class pool party, you have the following algebraic equation which expresses the given situation:

y = 11x + 625

If there are 26 people in the party, that is, if x = 26, the cost is:

y = 11(26) + 625

y = 286 + 625

y = 911

Hence, the cost is $911

2. Now, we have to solve for x as follows:

Therefore, in summary, the regular price is $700.

Answer:

Domain: (-∞, ∞)

Range: (-∞, -9]

Step-by-step explanation:

a)

The oven devaluated from $1970 to $270 in 10 years.

Since each year it looses the same value, divide the change in the price over the time interval to find the rate of change of the value with respect to time.

To find the change in price, substract the initial price from the final price:

The change in price was -$1700.

Divide -1700 over 10 to find the change in the price per year:

The initial value of the oven was $1970, and each year it looses a value of $170.

Then, after x years, the value will be equal to 1970-170x.

Then, the linear equation that models the value of the oven, y, after x years of use, is:

b)

To find the value of the oven after 2.5 years, substitute x=2.5:

Then, the value of the oven after 2.5 years is $1545.

c)

To find the y-intercept, substitute x=0:

The y-intercept is the initial value of the oven when 0 years have passed.

The rate of change of the distance between the police car and the truck after 10 minutes is approximately 193.66 m/s

The rate of change of a function is the rate at which the output of the function is changing with regards to the input.

The velocity of the police car = 160 km/h south

The velocity of the truck = 140 km/h east

Distance of the police car from Sioux Falls = 60 km north

Distance of the truck from Sioux Falls = 50 km east

Required;

The rate at which the distance between the vehicles is changing at t = 10 minutes

Solution;

Let d represent the distance between the vehicles, we have;

d² = x² + y²

Where;

x = The distance of the truck from Sioux falls

y = The distance of the police car from Sioux Falls

Which gives;

[tex] \displaystyle{ \frac{d}{dt} d^2= \frac{d}{dt}(x^{2}) +\frac{d}{dt} (y^{2}) }[/tex]

Which gives;

[tex] \displaystyle{ 2 \cdot d \cdot \frac{d}{dt} d=2 \cdot x \cdot \frac{dx}{dt} + 2 \cdot y \cdot\frac{dy}{dt} }[/tex]

After 10 minutes, we have;

y = 60 - (10/60)×160 = 100/3

x = 50 + (10/60)×140 = 220/3

d = √((100/3)² + (220/3)²) = 20•(√146)/3

[tex] \displaystyle{ \frac{d}{dt} d=\frac{2 \cdot x \cdot \frac{dx}{dt} + 2 \cdot y \cdot\frac{dy}{dt} }{2 \cdot d }}[/tex]

Which gives;

[tex] \displaystyle{ \frac{d}{dt} d= \frac{2 \times \frac{220}{3} \times 140 + 2 \times \frac{100}{3} \times 160}{2 \times \frac{20 \times \sqrt{146}}{3}}}[/tex]

[tex] \displaystyle{ \frac{2 \times \frac{220}{3} \times 140 + 2 \times \frac{100}{3} \times 160}{2 \times \frac{20 \times \sqrt{146}}{3}}\approx 193.66}[/tex]

We got to use the Secant-Tangent Theorem, here. It says that AC² is equal to the distance BC times the distance from C to the circumference. Let's denote the point in OC where it intercepts the circumference by D, so:

Beucase the radius is equal in all points of the circumference, OA=OB=OD, so BC = OA + OC, and CD = OC - OA. So,

The value of the expression −|a + b|/2 − c when a =1 2/3 , b=−1 , and c=−3 is 8/3

From the question, the expression is given as

−|a + b|/2 − c

Also, we have the values of the variables to be

a =1 2/3 , b=−1 , and c=−3

Rewrite a as

a = 5/3

So, we substitute a = 5/3  b=−1 , and c=−3 in −|a + b|/2 − c

This gives

−|a + b|/2 − c  = −|5/3 - 1|/2 + 3

Evaluate the difference in the expression

−|a + b|/2 − c  = −|2/3|/2 + 3

Divide

−|a + b|/2 − c  = −|1/3| + 3

Remove the absolute bracket and solve

−|a + b|/2 − c  = 8/3

Hence, the solution is −|a + b|/2 − c  = 8/3
