Answer:

The domain is (all possible values of x) \{0,1,2,3,4,5\}

The range is (all possible values of f(x)) \{250,200,150,100,50,0\}

Step-by-step explanation:

A contestant on a game show is given $250.  He is asked five questions and loses $50 for every wrong answer.

  • If he answer all 5 questions correct, then he will still have $250;
  • If he answers 4 questions correct and 1 question incorrect, he will have $200;
  • If he answers 3 questions correct and 2 questions incorrect, he will have $150;
  • If he answers 2 questions correct and 3 questions incorrect, he will have $100;
  • If he answers 1 question correct and 4 questions incorrect, he will have $50;
  • If he answers 5 questions incorrect, he will have $0.

Let x be the number of wrong answers. Then you get a relationship

\begin{array}{cc}x&f(x)\\ 0&250\\1&200\\2&150\\3&100\\4&50\\5&0\end{array}

The domain is (all possible values of x) \{0,1,2,3,4,5\}

The range is (all possible values of f(x)) \{250,200,150,100,50,0\}

A box contains 17 marbles, 13 blue marbles, and 23 white marbles. What is the part-whole ratio of red marbles in the box.
sergij07 [2.7K]
Since the ratio is part-Whole, first you need to find the whole. If you add all of the marble colors together (17+13+23) you get the total marbles (53) in the box. The ratio of red marbles to the total would be 17 to 53.

5. Which of the following is the equation of a line. that passes through the points (0.8) and (6.4)7 Use of
andriy [413]

See in the explanation

<h2>Explanation:</h2>

In this exercise, <em>we have the following points:</em>

(0.8) \\ \\ (6.4)

And <em>the following linear equations:</em>

(1) \ y=-x+8 \\ \\ (2) \ y=\frac{3}{2}x+6 \\ \\ (3) \ y=-\frac{4}{5}x+4 \\ \\ (4) \ y=\frac{1}{2}x+8

When plotting these graphs, we find the following facts:

<h3>For (1):</h3>

We see the graph in the first figure below. The graph only passes through the point (0, 8)

<h3>For (2):</h3>

This is the second graph below. The graph passes neither through point (0, 8) nor (6, 4)

<h3>For (3):</h3>

This is the third graph below. The graph passes neither through point (0, 8) nor (6, 4)

<h3>For (4):</h3>

This is the fourth graph below. The graph only passes through the point (0, 8)

So, <em>there is no any equation of the line that passes through the points (0.8) and (6.4) at the same time.</em>

consider the right triangle inside the circle with a center at point E(1,1). which equation can be used to show how he pythagore
Kruka [31]

The standard form of a circle is:

(x-h)^2+(y-k)^2=r^2

Where

(h, k) is the center

r is the radius

Since the center is (1, 1), we can write:

(x-1)^2+(y-1)^2=r^2

EG (hypotenuse of the right triangle) is the radius of the circle. Thus, we can say >>>

(x-1)^2+(y-1)^2=(LengthOfEG)^2

The correct answer is

MaryJo decided to solve the equation 3x-2= -x-6 by entering each of the expressions into her graphing calculator. To solve the e
miss Akunina [59]
Note that the problem states that you only need to check the solution she got for x...so we don't have to worry about y in this case. (YAY)

To verify MaryJo's answer, simply solve the equation for x:

3x - 2 = -x - 6
3x (+ x) - 2 = -x (+ x) - 6
4x - 2 = -6
4x - 2 (+ 2) = -6 (+ 2)
4x = -4
4x/4 = -4/4
x = -1

Since this conforms to MaryJo's answer, she did indeed find the correct solution for x.
