Answer:

Adriana made the most money

Step-by-step explanation:

The total selling price of the unwanted items sold by both Mario and Adriana is given.

We can look for the greater figure, or better still find the positive difference between them to know which one is greater.

So, Selling price for Adriana = $294

And, Selling Price for Mario = $249

The difference in value is $294 - $249 = $45

So, Adriana made $45 more than Mario.

If original function is y= 3x-2 than inverse function is

3x=y+2 => x= (y+2)/3 than when we change the roles

we get inverse function y=(x+2)/3

Good luck!!!

How are rational functions similar to linear, quadratic, or exponential functions? How are they different? When are these simila

jeyben [28]

Answer:

See explanation below for further details.

Step-by-step explanation:

A rational consist of two real numbers such that:

$\frac{a}{b} =c$

If c is a polynomial with a certain grade, then, both the numerator and the denominator must be also polynomials and the grade of the numerator must be greater than denominator.

If c is linear function, that is, a first order polynomial, then a must be a (n+1)-th polynomial and b must be a n-th polynomial.

Example:

If $a = x^{2}$ and $b = x$ , then:

$c = \frac{x^{2}}{x}$

$c = x$

If c is a quadratic function, that is, a second order polynomial, then a must be a (n+1)-th polynomial and b must be a n-th polynomial.

Example

If $a = 3\cdot x^{3}$ and $b = x$ , then:

$c = \frac{3\cdot x^{3}}{x}$

$c = 3\cdot x^{2}$

But if c is an exponential, both the numerator and the denominator must be therefore exponential function and grade of each exponential function must different to the other.

Example

If $a = 10^{2x}$ and $b = 3\cdot 10^x$ , then:

$c = \frac{10^{2\cdot x}}{3\cdot 10^{x}}$

$c = \frac{1}{3}\cdot 10^{2\cdot x -x}$

$c = \frac{1}{3}\cdot 10^x$

Otherwise, c would be equal to a constant function, that is, a polynomial with a grade 0.

If $a = 5\cdot e^{x}$ and $b = -3\cdot e^{x}$ , then:

Example

$c = \frac{5\cdot e^{x}}{-3\cdot e^{x}}$

$c = -\frac{5}{3}$

It is worth to add that exponential functions can be a linear combination of single exponential function, similar to polynomials.

Example

$5\cdot a^2\cdot x -9$

Susan is going to watch a movie in her collection she has 5 action movies 4comedies and 3 dramas she will randomly select one mo

Ivenika [448]

Answer:

9/12 or 75%.

Step-by-step explanation:

Let's first add the choices all up.

5+4+3= 12.

We have 12 movie choices in total.

Now, we know that we have 3 drama movie choices...so the chance we will choose drama is 3/12, but we are not finding that. We want the chance she will NOT choose drama, so that would be 9/12.

*Since the chance she will choose drama is 3/12, the chance she will not choose is 9/12. 9+3 is 12, the total amout.*

If y varies directly as x and y = 144 when x = 12, what is the value of y when x = 17?

Burka [1]

$y=kx \\ \\
y=144 \hbox{ when } x=12 \\
\Downarrow \\
144=k \times 12 \\
k=12 \\ \\
y=12x \hbox{ and }
x=17 \\
\Downarrow \\
y=12 \times 17 \\
y=204 \\ \\
\boxed{y=204} \hbox{ when } x=17$

No link please I need a answer

Kryger [21]

Answer: 10

Step-by-step explanation:

We need to find the hypotenuse (the hypotenuse is the diagonal side of a right triangle), so we can use this formula: $a^2+b^2=c^2$

The two "legs" are a and b (it doesn't matter which leg is a and which leg is b), but the most important thing is that the hypotenuse is c.

So, we now know that we have to solve for c. To solve for c, substitute the values shown in the image for a and b

$a^2+b^2=c^2$

$6^2+8^2=c^2$

$36+64=c^2$

$100=c^2$

$\sqrt{100}=c$

$c=10$
