Mathematics
1 answer:
djyliett [7]2 years ago
7 0

Answer & Step-by-step explanation:

The definition of a function is that every input, x, must have only one output, y. So, for every x value, there should be only one y value with it. If you have two x values that are the same and have different y values, then that is not a function. The only answer that showcases this is letter D.

<em>1 → 2</em>

<em>2 → 3</em>

<em>3 → 4</em>

<em>4 → 5</em>

In this function, every input has one output and each x value is different.

KINNDAAAA need help. Will give Brainly! Need the full equation pls!
Alexxandr [17]
Hey, I’m pretty sure the answer is y=1/2x + 0.

To explain, we can plug the x value into the equation for all of the x values, and we will get our y value.

So the first one,

y=1/2(1) + 0 —> 1/2

The second one,

y=1/2(2) + 0 —> 1

And so forth, the rest of the equations will be correct. I hope that helps ! :D

ikadub [295]

Answer:

Step-by-step explanation:

line up $ and % data like this:

$2.79 represents 100%

$3.79 represents  X%

cross multiply

X*2.79 = 3.79*100

divide both sides by 2.79

X= 3.79*100 / 2.79 ≈ 136%

so it increased 36%

Is 50 a perfect square ? Explain your answer please 
xeze [42]
No, 50 is not a perfect square.  A perfect square is any number that can be divided by any number to get the quotient as the same number AND the quotient must be rational.  When you divide 50 so that the quotient equals the divisor, you will get an irrational number.  Therefore, 50 is not a perfect square.
