The multiply choice were worth 4 points.
Gretchen= 18x+19
Ezia= 15x+31

So basically you can enter any number. At first I picked 3 and then I did the math and I got 73 points for Gretchen and 76 points for Ezia.

Then I pick four and then I got 91 points for them both. This is how I got the answer:

18x+19=15x+31
18(4)+19=15(4)+31
72+19=60+31
91=91

I hope this get a clear understanding of how I got the answer :D

The <em>correct answer</em> is:

4 points per multiple choice question

Explanation:

Let x be the amount each multiple choice question is worth. Since Gretchen answered 18 of them correctly, we would write this as 18x. Adding the 19 points for the essay question, we have 18x+19.

Since Ezia answered 15 multiple choice questions correctly, we would write this as 15x. Adding the 31 points for the essay question, we have 15x+31.

Since they had the same score, we set these equal to one another:

18x+19 = 15x+31

To solve this, first subtract 15x from each side:

18x+19-15x = 15x+31-15x

3x+19 = 31

Subtract 19 from each side:

3x+19-19 = 31-19

3x=12

Divide each side by 3:

3x/3 = 12/3

x = 4

Each question is worth 4 points.

Solve the following system of equations algebraically<br> 3x-y=0<br> 5x+2y=22

Lyrx [107]

3x - y = 0 ⇒ 2(3x - y = 0 ) ⇒ 6x - 2y = 0

5x + 2y = 22 ⇒ 1(5x + 2y = 22) ⇒ <u>5x + 2y</u> = <u>22 </u>

11x = 22

x = 2

3x - y = 0 ⇒ 3(2) - y = 0 ⇒ 6 - y = 0 ⇒ 6 = y

Answer: x=2, y=6

Answer:

The answer is y = -1/3x + 5 !

Step-by-step explanation:

If you observe the line, the y-intercept is 5, from the point in the graph (0,5). From that point, we can see that the rise over run is -1/3. Thus, y = -1/3x + 5.

The range of which function is (2, infinity)? y = 2x y = 2(5x) y = 5x 2 y = 5x 2

vova2212 [387]

The function which has range (2, infinity) from the provided function is y = 5ˣ +2. Option 4 is correct.

<h3>What is range of function?</h3>

Range of a function is the set of all the possible output values which are valid for that function.

The function whose range is (2, ∞) has to be find out.

The first function given in the problem is,

$y=2^x$

This function has the periodic function with period of logarithmic function and the range of this function is all the real number. This is not the correct option.

The second function given in the problem is,

$y=2(5)^x$

This function has the periodic function with period of logarithmic function and the range of this function is all the real number. This is not the correct option.

The fourth function given in the problem is,

$y=(5)^x+2$

This function is translated 5 units up to the function 5ˣ which has the range (0,∞).

Thus, the range of this function is (2, ∞).

Hence, the function which has range (2, infinity) from the provided function is y = 5ˣ +2. Option 4 is correct.
