Please, help! Pretty urgent!
jekas [21]

Answer:

1. As definition, in a function, the set of all possible inputs or possible x values is called the domain.

=> Option 2 is correct.

2. As definition, in a function, the set of all possible outputs or possible y values is called the range.

=> Option 3 is correct.

3. You pay a fixed amount of 70$ and 3$ for each movie.

=> A function that models the total cost: y = 70 + 3x

=> Option 1 is correct

4. Similar to the 3rd, you pay a fixed amount of 5$ to enter and 2$ for each ride.

=> A function that models the total cost: y = 5 + 2x

=> Option 3 is correct.

5.  The average rate of change (R) of f(x) = x2 + 1 from x = 0 to x = 3 is actually the rate of change of line passes (0, 1) and (3, 10) as shown in picture.

=> R = (10 - 1)/(3 - 0) = 9/3 = 3

=> Option 1 is correct.

6. As property of vertical line:  75 = x - 10 + 20

=> x = 75 + 10 - 20 = 65 deg

As property of complement angles: 75 + y = 180

=> y = 180 - 75 = 105 deg

=> Option 2 is correct.

7. Yes, the two triangles are congruent (Side-Angle-Side case) with two sides are equal and the pair of angles created by those pair of 2 sides are also equal.

Hope this helps!

PLEASE HELP <br> WHAT ARE THE coordinates for the center of the hyperbola??
solong [7]

Answer:

The coordinates of the center of the hyperbola are (1,-3)

Step-by-step explanation:

Equation of a hyperbola:

The equation of a hyperbola with center (x_0,y_0) is given by:

\frac{(x - x_0)^2}{a^2} - \frac{(y - y_0)^2}{b^2} = 1

In this question, we have that:

-x_0 = -1 \rightarrow x_0 = 1

-y_0 = 3 \rightarrow y_0 = -3

The coordinates of the center of the hyperbola are (1,-3)

A car is traveling at a steady speed. It travels 2 1/2
Ksivusya [100]

Answer:

It will travel

33 \frac{1}{4}  \: miles

in 45 minutes.

Step-by-step explanation:

We can solve using proportions.

\frac{ 2\frac{1}{2} \: miles}{ 3\frac{1}{3} \: minutes}  =  \frac{x}{45 \: minutes} \\  \\  \frac{ 3\frac{1}{3} x}{ 3\frac{1}{3} }  =   \frac{ 112\frac{1}{2} }{ 3\frac{1}{3} }    \\  \\  x = 33\frac{3}{4}
