The rates of change of points earned by both players tell us that;

Player A gains more point than Player B does for each correct answer in this round.

We are told that x is the number of

number ofquestions answered correctly and y is the score.

Now, for player B;

For 1 correct answer, he got a score of 4

For 2 correct answers, he got a score of 5

For 3 correct answers, he got a score of 6

For 4 correct answers, he got a score of 7

This means that rate of change of Player B is;

3 points for every extra question answered correctly. .

Now, the formula for player A's points is;

y = 4x + 3

Rate of change of points here is gotten by finding the derivative. Thus;

dy/dx = 4

This means player A earns 4 points for every extra question answered correctly.

In conclusion, it mean that Player A gains more point than Player B does for each correct answer in this round.

Which of the followingis multiplicative of -a? (-1/a a 1 1/a)​
Elodia [21]

Given:

The given value is -a.

To find:

The multiplicative inverse of -a.

Solution:

We know that y is the multiplicative interval of x if xy=1.

Let x be the multiplicative inverse of the given value -a. Then,

(-a)\times x=1

Divide both sides by -a.

x=\dfrac{1}{-a}

x=-\dfrac{1}{a}

Therefore, the multiplicative inverse of -a is -\dfrac{1}{a}. Hence the correct option is A.

I need to know how to do these
Allisa [31]

I'll do one, you can use it as a basis for your answer.

7x ^{2}    + 6 = 13

Subtract 6 from both sides to get X by itself.

7x ^{2}  = 7

Now we divide by 7 for both sides as well.

x {}^{2}  = 1

Now we find the square root of 1 to figure out X.

\sqrt{1}  = 1

Therefore, X=1.
